Amazon reviews have often become a shitshow of everything from the hilariously outrageous to just plain disturbing. Instead of rummaging through your bag for your wallet or phone, keep both protected and in place. GOFAR Services, LLC - Appliance Repair Houston, TX - Chapter 7MAYTAG "NEWTON" MACHINES (for Maytag Performa and Atlantis models,see Chapter 7a)NOTE: Chapter 2 covers problems common to almost all washer designs. Q- Would removal of the dam help alleviate upstream flooding problems suffered by residents of the Family Farm neighborhood in Woodside?
A- Searsville Dam was not designed to provide any flood protection benefit downstream and has caused flooding upstream. A- While the dam was well built, the average age for a dam is reported, by Stanford, to be 40 years and Searsville Dam is 120 years old. Q- Stanford currently uses the reservoir for non-potable water use, such as irrigation, landscaping and fire-fighting. A- As with other completed dam removals, this project design would maintain or replace existing owner needs with improved facilities and ease of operation.
A- Recent studies and completed dam removal efforts have shown that dam removal is almost always less expensive than eventual dam safety retrofitting, installation of required fish passage facilities, and ongoing maintenance costs. A- Fortunately, there are many sources of funding for dam removal and ecosystem restoration projects of this kind. A- The existing ecosystem has emerged around an artificial and unsustainable reservoir that is filling in with sediment.
Q- What effects would removal -- including possible flushing of sediment -- have on the recovering population of steelhead elsewhere in the watershed? A- The dam has held back sediment for over a century and altered the natural flow of gravels and beneficial sediments downstream creating a a€?hungry watera€? situation that has impacted bank erosion and the native habitat for steelhead. Corte Madera Creek and the many tributary streams (above) contain excellent habitat and continues to support wild, rainbow trout (below), which are the descendants of sea-run steelhead. Q- The current wetlands support a rich bird habitat and foraging ground for bats a€“ would this be protected with the removal? A- Some of the recently established wetlands and habitat utilized by birds and bats can remain with dam removal and design plans would maximize the protection of sensitive areas in a manner similar to other successful dam removal efforts.
Stanford officials have often wondered about the impacts of dam removal on vegetation established on the reservoir and possible negative impacts to neotropical migrant birds that have been observed here in high abundance.
Searsville Dam removal would restore miles of currently buried streams, riparian forests and thick border habitats, and increase the amount of highly productive fringe wetland habitat that these riparian zones provide. Overall, the project could trade in the unsustainable, artificial, reservoir habitat for a net gain in stream habitat, riparian forest habitat, fringe wetland habitat, historic wetland ponds, and upland habitat. A- Dam removal will eliminate the artificial reservoir habitat that currently allows for the breeding and dispersal of several exotic and invasive species that prey upon and compete with the native species. A- Dozens of large dams have been successfully removed and hundreds of medium and smaller dams have been taken out over the past couple decades. A- Over 500 dams have been removed in the United States in recent years and several dams that were about the size of Searsville, and larger, have recently been removed from rivers around the country.
The mouth of San Francisquito Creek (above) is near several wetland restoration projects in need of sediment.
Q- How would the removal of 60 feet of concrete blocks affect the biological preserve and surrounding communities?
A- Removal of the concrete blocks would be a short-term disturbance to the Jasper Ridge Biological Preserve and surrounding communities. A- Doing nothing at the dam and reservoir is not an option that any stakeholders are currently considering or embracing due to the imminent negative impacts of such a non-action. Q- How will you work with Jasper Ridge Biological Preserve and other watershed stakeholders to ensure their concerns are being met?
A- Members and supporters of the Beyond Searsville Dam Coalition have been collaborating with Jasper Ridge Biological Preserve, Stanford University, San Francisquito Joint Powers Authority, San Francisquito Watershed Project, local jurisdictions, government agencies, community groups, and other non-profit groups for several decades on a variety of watershed related projects.
Jasper Ridge Biological Preserve Director, Philippe Cohen (green cap), and Stanford Engineering Professor, David Freyberg (at right), atop Searsville Dam talking to a group from the Salmonid Restoration Federation conference who were interested in dam removal. 1) What is a dam?a€?There are a number of technical and legal definitions of a dam but generally it is any structure that impounds or diverts water. However, this inventory only covers dams that meet minimum height and impoundment requirements, so an unknown number of small dams are not included in the inventory. 3) Which state has the most dams?a€?According to the NID, Texas has the most dams of any state at 6,798.
4) Who regulates dam operations?a€?A number of state and federal agencies are responsible for regulating dams. 5) How many dams actually produce power?a€?FERC regulates approximately 2,300 hydroelectric producing dams. 7) Why are some dams being removed?a€?There has been a growing movement to remove dams where the costs - including environmental, safety, and socio-cultural impacts - outweigh the benefits - including hydropower, flood control, irrigation, or recreation - or where the dam no longer serves any useful purpose. 8) How are dams removed?a€?Because dams and rivers vary greatly, physical removal strategies and techniques may also vary on a case by case basis.
9) How many dams have been removed to date?a€?Currently, American Rivers is aware of more than 600 dams that have been removed over the past 50 years in this country.A  We are still in the process of gathering this data, so that figure is likely to increase as more information becomes available. 10) How much does it cost to remove a dam?a€?Because the size and location of dams vary so greatly, the cost to remove an individual dam can range from tens of thousands of dollars to hundreds of millions of dollars. 11) Who owns the dams that are being removed?a€?Private businesses, federal agencies, state agencies, local governments, or public utilities may own dams.
12) Who pays for dam removal?a€?Who pays for the removal of a dam is often a complex issue.
13) Who decides that dams should be removed?a€?The decision to remove a dam is made by varying entities, depending on the regulatory oversight of the dam. 14) Can rivers be restored through dam removal?a€?Although most rivers cannot be completely restored to historic conditions - simply because of the amount of development that has occurred on and along them - dam removal can often recreate conditions that move the river towards those historic conditions.
15) What benefits do dams provide?a€?Dams may provide a variety of benefits, including water supply, power generation, flood control, recreation, and irrigation. 16) How can the benefits of a dam be replaced when it is removed?a€?While dams serve a number of human needs, society has developed ways to address many of these needs without dams. Rather than plugging rivers with multiple hydropower dams, a cheaper and less environmentally harmful solution is to use existing energy efficiency technologies.
17) Is it cost effective to remove a dam?a€?Dam removal can be expensive in the short term, but in most cases where dams have been removed or are being considered for removal, money is actually saved over the long term. 18) Will the removal of a dam matter if other dams in the system are not removed?a€?Some rivers are so heavily developed and dammed that removal of one dam on that river will only return flows to a small portion of the river. 19) Are we going to decide in twenty years that we need to start building dams again?a€?We have learned a lot in the past twenty years about the many impacts dams have on rivers, and we have learned many alternatives to damming rivers. 21) What are the potential downsides to dam removal?a€?Dam removal does result in fundamental changes to the local environment.
How quickly do rivers recover after dam removal?a€?Rivers are very dynamic and resilient systems.

GOFAR Services, LLC - Appliance Repair Houston, TX - Chapter 4COMPRESSOR IS RUNNINGBUT REFRIGERATOR IS NOT COLDCOMPRESSOR IS RUNNING BUT REFRIGERATOR IS NOT COLDBefore you perform any of the other tests in this chapter, make sure that the compressor is running.
THIS chapter covers only diagnosis and repairs peculiar to CERTAIN Maytag-designed machines. As the elevation of the reservoir and trapped sediment were lowered, upstream flooding issues caused by the dam are expected to be eliminated.
The dam removal design plan can maximize flood protection benefits to downstream communities. Searsville Dam provides a moderate amount of water that can easily be replaced with a less harmful water diversion facility that allows for improved functionality to Stanford. Federal, state, local, private, and non-profit entities are all providing large grants and donations to dam removal efforts nationwide. Some of the current vegetation and habitat that has grown up on the upstream end of the reservoir can be maintained with the dam removal design.
Dam removal would provide additional spawning gravels below the dam for steelhead as well as more natural water flow regimes and anticipated improvements to water quality. These native trout are genetically isolated by the dam and their survival is at risk due to inbreeding and loss of genetic diversity.
It is critical to understand that while the artificial, and disappearing, open-water reservoir habitat will be reduced, the historic and ecologically unique habitat buried by the dam and reservoir will be restored. In addition, much of the established riparian vegetation at the upper end of Searsville Reservoir could remain with theA  dam removal design.
The historic map below shows what this habitat looked like before the dam and what it can look like again with dam removal and ecosystem restoration. Several species of non-native bass, sunfish, and panfish as well as bullfrogs occur in the warm, artificial, flat-water of Searsville Reservoir. Much more complicated dam removals have been completed that involved hydro-power replacement, polluted sediment disposal, adjacent development, and other challenges that this project would not have.
There are also several dams that are planned for removal over the next couple years that are many times larger in size and in the amount of stored sediment.
A portion of the sediment can be transported for other uses, including the stated desire for it at planned San Francisco Bay wetland restoration projects or nearby agricultural sites. We will continue to work with all of these stakeholders to address their concerns, as we feel that the safety and ecosystem issues are in our mutual interest and that the most effective project will occur when shared goals are best addressed. While many progressive leaders at Stanford acknowledge the potential benefits of dam removal and the need for comprehensive studies to analyze specific dam removal alternatives, many watershed stakeholders are concerned that several individuals at Stanford are misrepresenting the issue and standing in the way of productive collaboration and investigation on this critical watershed decision that impacts all stakeholders.
There are approximately 75,000 dams in the US Army Corps of Engineers' (Corps) National Inventory of Dams (NID), which is the most comprehensive inventory of dams nationwide. Of the 75,000 dams in the database, approximately 66,000 are located on rivers (the remainder impound water off-river). Generally, the process involves drawing down the reservoir, potentially removing the sediment built up behind the dam, removing the structure, and mitigating for downstream effects of increased flow and sediment re-suspension. Most of the dams removed to date have been owned privately, by local government, or by public utilities. In past cases, removal has been financed by the dam owner, local, state and federal governments, and in some cases agreements whereby multiple stakeholders contribute to cover the costs.
In most cases, the dam owner itself is the decision-maker, often deciding that the costs of continuing to operate and maintain the dam are more than removing the dam.
For example, fish are returning to historic stretches of river that had been previously obstructed on Butte Creek in California, theA Souadabscook River in Maine, and the Clearwater River in Idaho, as a result of dam removals. For instance, flood control can often be accomplished more effectively and for less money by restoring wetlands, maintaining riparian buffers, or moving people out of the floodplain. Removal eliminates the expenses associated with maintenance and safety as well as direct and indirect expenses associated with fish and wildlife protection (e.g.
The reservoir will be eliminated, and with it the flat-water habitat that had been created.
Experience has shown that natural river systems can be restored relatively rapidly after dam removal. If it is not running, see Chapter 5.Some refrigerators are very quiet and smooth when they operate.
Amazon customer Adam tells a "not so funny story" in his feedback for the HyperX Cloud II Gaming Headset. The obvious reason for this is that modern Luxor is also the site of ancient Thebes with its famous temples of Luxor and Karnak, as well as the fabled Valley of the Kings where the storied rulers of antiquity a€” including Tutankhamun a€”were buried. If you do not read Chapter 2 thoroughly before you read this chapter, you probably will not be able to properly diagnose your machine!!!!7-1 BASIC OPERATIONThe design uses a reversing motor, which is belted to both the pump and the transmission, using two different belts. The valley and historic wetlands that are buried beneath Searsville Dam and Reservoir once provided natural flood protection benefits by filling and absorbing winter rains and then slowly releasing flows following the peak flow event.
Large cracks that remain on the dam were observed by the dam caretaker immediately after the 1906 earthquake. The shrinking reservoir provides a fading amount of storage capacity that can be replaced with existing off-stream reservoirs, expanded storage areas, new off-stream storage, and possible dredging of the remaining upper Searsville Reservoir areas. Almost all dam removal studies and construction efforts are being partially or fully funded with these available grants. In addition, miles of historic stream, riparian, and wetland habitat currently buried can be revived and restored with the dam removal.
The existing downstream steelhead population is able to migrate up all other existing spawning and rearing tributaries in the watershed and away from any potential short-term disturbances from the dam removal.
Several miles of stream habitat and associated riparian forests, comprising over 6 different tributary streams, can be reestablished. These species are able to breed in this artificial habitat and spread downstream of the reservoir were they can prey on and compete with threatened steelhead trout, other native aquatic species; including amphibians and even small birds and mammals. Habitat restoration of this size has been successfully completed at hundreds of locations and many dam removal projects have enabled stream habitat and native wildlife to restore themselves quickly.
See our Dam Blog page and American Rivers website for more information on completed and planned dam removal projects.


Noise abatement methods, scheduled use of roads by trucks, use of cleaner burning biodiesel in equipment operation, working around Preserve activities and research, and other determined actions could be implemented to reduce impacts.
Dredging the reservoir and maintaining some open water has also been considered, but has limited benefits and most of the existing ecosystem and safety problems with the dam would remain.
We firmly believe that a collaborative, well-designed dam removal effort can be in the best interest of Stanford University and the entire watershed community. Non-federal dams that produce hydropower are regulated by the Federal Energy Regulatory Commission (FERC). According to the NID, Oroville Dam, on the Feather River in California, is the tallest dam in the United States, measuring in at 770 ft. State dam safety offices can often order a dam to be removed if there are major safety concerns. Updating antiquated irrigation systems and replacing inappropriate crops can dramatically reduce the need for dams and reservoirs in the arid West. Many dams that have been removed no longer had any beneficial use or that use was very limited. In some cases, this additional section of river is enough to sustain crucial populations of endangered or threatened species of fish, mollusks, and other wildlife.
In the next twenty years we are likely to learn even more about alternatives to dams and the impacts of dams on rivers. Wetlands surrounding the reservoir will also be drained, although new wetlands are often created both in the newly restored river reach above the former dam site and in the river below.
For example, spawning fish returned to theA Souadabscook River in Maine only months after a dam was removed, and the flushing of the sediment from the Milwaukee River in Wisconsin following the Woolen Mills Dam removal took only six months.
Five stars, would buy again, oh, and they really helped block out the sounds of someone getting stabbed in the apartment unit above him. A few weeks ago a man got thrown out of the window of the apartment directly above mine, and my pair of HyperX Cloud 2 headphones was not able to cancel out the sounds of the window breaking and the man's neighbor crying out for his friend to wake up." And another purchaser is ready to call actual bullshit on the whole situation, noting that the headphones themselves aren't noise-canceling (though the mic is). As long as tourists were able to sail the Nile, Luxor was the magnet that caused them to endure the long and difficult journey to the south. All over the nation, restoration projects are being constructed that restore historic wetlands and adjacent riparian overflow areas to provide the dual benefits of ecosystem restoration and natural flood protection. It is not known what the current structural condition of the dam is because it has been 43 years since the Division of Safety of Dams (DSOD) has inspected the foundation, toe, and groins of the dam. New diversion facilities can tie into existing storage facilities, irrigation, and landscaping pipelines and improve water delivery. One state agency, the Department of Water Resources, already offered to study alternatives at Searsville Dam, including removal, at no cost to Stanford. The artificial reservoir ecosystem also currently harbors many exotic species of fish and frogs, which would be eliminated or drastically reduced in numbers, benefiting native species.
As observed with other dam removal efforts, such as the Marmot Dam removal in Oregon, wild salmon and steelhead migrated upstream of the removed dam within several days of it being removed and reestablished themselves into historic habitat, expanding their distribution and improving their population health. Biologically-rich wetland ponds and seasonal overflow wetland areas that are currently covered by the reservoir can be restored along with acres of transitional and upland habitat. Dam removal and ecosystem restoration plans can minimize the risk of additional exotic species becoming established during the restoration effort and help to minimize future exotic introductions. Other sediment alternatives such as slurry piping and controlled sediment transport can be utilized to design the best plan to address project complexities. As with so many other recently completed dam removal efforts, project stakeholders decided that the long-term gains to the ecosystem, dam owner, and surrounding communities warranted the short-term disturbance of dam removal. Only dam removal has the combined benefits of eliminating the safety liability of the dam, providing a free flowing stream, restoring historic habitat (wetland, stream, riparian), eliminating or reducing non-native species, providing unimpeded steelhead migration, and providing natural flood protection features. Non-federal dams that do not produce hydropower are regulated by the state in which they reside. The dam with the largest impoundment is Hoover Dam, on the Colorado River in Nevada, which stores approximately 30 million acre-feet of water.
The Federal Energy Regulatory Commission can order a hydropower dam under their jurisdiction to be removed for both environmental and safety reasons. In addition, removal often generates income from newly available recreation opportunities - including fishing, kayaking, and rafting - which may actually result in a net economic benefit. Sediment that collects behind a dam, sometimes over hundreds of years, may contain toxics such as PCBs, dioxide, and heavy metals.
This dude even explains that the screams and sounds of your neighbor getting stabbed isn't even the type of noise that noise-canceling technology filters out.
A  The destruction of shops and residences near the Avenue of the Sphinxes in Luxor.A A  Photo by William PeckIn addition to the antiquities, the town itself was a picturesque attraction where foreign visitors might experience a bit of the daily life of the local people. When viewed from the top, the motor turns clockwise for the agitation cycle, and counterclockwise for the spin cycle.
In addition, dam removal efforts nationwide are being awarded funding to precede the dam removal with major downstream flood protection projects to increase channel capacity, replace undersized bridges, improve levee systems, and ensure that flood risks are reduced with the project.
Many earthquakes and several decades have past since this last detailed foundation inspection. The remaining upper reservoir, west of Portola Road, is an historic wetland pond that preceded the construction of Searsville Dam. Water quality and habitat conditions downstream are expected to improve with dam removal, as has been the case elsewhere. Dam removal projects have consistently shown a strong benefit to salmon and steelhead populations in watersheds across the world. An amazing and diverse array of habitat types and species will be restored for birds, bats, steelhead, and the full array of native species. Most of the non-native species utilizing Searsville Reservoir cannot thrive in the natural flowing stream environment. A combination of multiple sediment options has been used in other dam removal efforts and may provide the best way to deal with the sediment. The dam that provides the most hydroelectric power in the United States is Grand Coulee Dam, on the Columbia River in Washington, which generates 6180 megawatts (MW) of power.
Re-suspension of these toxic-laden sediments in the process of dam removal has the potential to damage downstream water quality and threaten the health of fish and wildlife and water users. According to the cop who interviewed us, the attacker rang the upstairs doorbell, and when the guy answered the attacker forced his way in and stabbed the guy.
The journey is not so difficult now: the flight from Cairo south to Luxor takes only one hour. This is an unprecedented opportunity to get massive funding and ease of permitting to reduce flooding, restore ecosystem health, and rebuild Stanforda€™s out-dated water supply facilities to a modern and sustainable state. Stanford is responsible for coordinating this inspection that DSOD has identified in the above 2007 inspection report as a a€?prudenta€? measure that should be taken. This pond can be maintained and continue to provide fire-fighting needs as well as water storage capacity and open-water wetland habitat benefits. Dam removal would also allow for the resurgence of annual steelhead trout runs to the watersheda€™s largest tributary for the first time in 120 years, bringing back a critical keystone species to the ecosystem.
Removal of Searsville Dam would open up over ten miles of historic spawning and rearing habitat in the largest tributary of the entire watershed, where high quality habitat and native rainbow trout persist. In addition, the dam removal will reestablish critical wildlife migration routes at this confluence of riparian corridors currently blocked by the dam and submerged by the reservoir. A detailed Dam Removal Alternatives Analysis study would identify the many options available. Short term impacts of the dam removal itself can include increased water turbidity and sediment buildup downstream from releasing large amounts of sediment from the reservoir, and water quality impacts from sudden releases of water and changes in temperature.
During agitation, the brake keeps the transmission casing from turning, and the drive pulley turns the transmission shaft. Beyond Searsville Dam requested that the DSOD require this study and they have informed Stanford that the study should happen before the end of 2012.
As part of the larger Searsville Dam removal and ecosystem restoration project, Stanford has an unprecedented opportunity to upgrade their water delivery and storage facilities with the benefit of available grant funding, eliminated safety liability, and ease of permitting.
The altered and artificial ecosystem would be transformed to a self-sustainable and native one. The remaining, and historic, upper pond located west of Portola Road can continue to provide open-water wetland habitat. Not only is much of the charm of the city disappearing, but the satisfaction once derived from the visit is disappearing too. During the spin cycle, the brake releases and the whole transmission starts slowly spinning around. As the dam and concrete continue to age, experience additional earthquakes, and as the reservoir fills in and transported sediment potentially scours the dam, the structural integrity is expected to be reduced over time. In addition, the upgraded water diversion and storage facilities can be designed to serve a critical secondary function of reducing flooding downstream by diverting and storing peak storm flows into collection basins as is being considered by the Joint Powers Authority in the watershed.
The active San Andreas Fault run adjacent to Searsville Reservoir, which can be seen as the oval blue shape near the center of the map, adjacent to the highest a€?Very-Violenta€? shaking severity level on the above image. Such multi-objective funding and permitting opportunities are being jumped at by dam owners across the country.
If you are still unsure and you own an ammeter, test the current draw of the compressor at the compressor leads. At the end of the spin cycle, the motor stops and the brake brings the basket to a stop. In the late '80's, Maytag redesigned the transmission.
Dam removal can eliminate the dam failure risk identified by San Mateo County and extensive downstream inundation. The result is the "orbital" transmission, which has just a few moving parts and is serviceable in the machine. Searsville Dam is listed as a a€?High Hazarda€? dam by the US Army Corps, State of California, and San Mateo County (pg. As noted in the above document, a High Hazard dam is defined as a dam whose failure would result in a€?probable loss of lives and significant property damagea€?. Springs attached to the motor mounting plate keep tension on the belts. The pump reverses with the motor, but there is no recirculation.
Stanforda€™s own report, SPEAR3, cites an analysis that determined failure of Searsville Dam could release a a€?catastrophica€? flow of 60,433 cubic feet per second, or a€?about 6 times the 500-year peak flow of 10,500 cfsa€? (Section 7.1 Page 7).
Stanforda€™s own report, SPEAR3,A  cites an analysis that determined failure of Searsville Dam could release a a€?catastrophica€? flow of 60,433 cubic feet per second, or a€?about 6 times the 500-year peak flow of 10,500 cfsa€? (Section 7.1 Page 7). In addition to geologic, aging, and seismic considerations, the dama€™s limited spillway design and operation and bypass flow drain pipe present additional safety challenges for dealing with dam overtopping during flood events and the ability to quickly drain the reservoir during an emergency.
Follow the safety precautions described in section 1-4(2).To open the front of the cabinet, remove the two screws at the bottom of the front panel. If the knob has an "off" setting which stops the compressor from running, it is thecold control.In the absence of an "off" setting, the easiest way to tell them apart is to pull the plastic knob off the control.
In order to diagnose these machines, you need to keep the lid up far enough to look inside, without tripping the lid switch. The idea is to keep the compartment at a different temperature from the rest of the food compartment; a more optimum temperature for the particular food that you're keeping in these compartments. This is known as "sweating." So-called "Energy Saver" switches control small, low-wattage "mullion" heaters in the side and door panels that prevent the outside of the refrigerator from getting cool enough for sweating to occur. Air flows over it by convection; the warm air rises and is replaced by cooler air from below. Replace as described in section 7-10. With the machine in "spin," look at the pump pulley beneath the machine with a mirror. If it is spinning, but water is not pumping, check for a clog in the hose between the tub and pump. If you hear the motor buzzing, but it doesn't start in either or both directions, test the capacitor (if any) and starting switch as described in sections 2-6(e) and 7-8.
Feel for a steady flow of warm air from the drain pan side; it should be obvious (see Figure 11). If it does start with the load removed, turn the pump and transmission pulleys by hand, in both directions, to see which is locked up. Note that the transmission pulley will normally be very stiff when turning it in the clockwise direction, as you look at the bottom of the washer.6) If the washer spins but does not agitate, check the agitator splines as described in section 7-11. See section 7-13.7-4 PUMP AND PUMP BELTRemove the pump belt and check to see if the pump will turn freely by hand. It has the veryimportantjob of directing airflow beneath the fridge, assuring that the condenser fan is drawing air over the condenser and not just sucking air in through the back of the fridge. They are sealed units and cannot be rebuilt.Replacing the condenser fan motor can be dirty and difficult.
When installing a new motor with bracket mounts, it may be easier to install the brackets loosely on the motor until you can locate the mounting screws in their holes. Thus, when trouble-shooting the evaporator fan, you must depress the door switch(es).Open your freezer door, depress all door switches and listen for the evaporator fan. Look first for a separate access panel or a tower within the freezer that houses the fan (Figure 14). Check for anything that may be blocking the fan, including ice from a backed-up defrost drain or a frost problem. If nothing is blocking the fan and it still does not run, check for voltage across the fan motor leads (with the door switch depressed, of course.)If you have voltage across the fan motor leads, the fan motor is bad.
Test as described in section 2-6(e). Maytag motors have a piggyback centrifugal starting switch. To make matters worse, the motor wire colors do not always correspond with the colors marked on the switch. Whenever removing the motor or switch from the machine, mark which wires came off which of the switch terminals.Draw a picture if you must. Make sure you differentiate in your notes between a motor wire and a wiring harness wire of the same color, and where each goes on the switch. If the drive motor does not start, try replacing the starting switch as described in section 2-6(e). Itcancause ice to build up in the internal ductwork.If you hear a "whistling" or "warbling" noise emanating from the fan motor itself or from the inside of the food or freezer compartment, it is probably coming from the evaporator fan motor.
If the motor STILL doesn't start, replace it. To remove the motor, first remove power from the machine.
Remove the plastic water shield from the motor, and mark and remove the wires. Remove the drive belts. Remove the four motor baseplate screws and lift the motor and baseplate out of the machine. Installation is the opposite of removal. Make sure you check the box that the new motor comes in for a wiring diagram.7-9 TRANSMISSIONI do not recommend the novice trying to replace a transmission in a Maytag washer, for several reasons.
They don't cost much.REPLACING THE EVAPORATOR FAN MOTORIn replacing the fan motor, you must make sure that the rotation of the new fan motor is the same as the old one. The easiest way to do this is to look for the shading poles on the old fan motor (Figure 16).If they are on opposite corners from the ones on the new fan motor core, it is a simple enough task to reverse the new rotor in its core.
And by the time you throw in a brake package, stem and seal kit, etc., it is usually just not worth it. Do not remove the icemaker (if installed.)Look at and feel the panel covering the bottom or back of the freezer compartment.
If both break, there will be NO tension on the belts and in addition, the motor shaft will probably be hitting the washer baseplate, causing a heck of a racket. The roller tracks can get clogged up with dirt, soap deposits or other obstructions. You will see a removable panel covering the entire back or bottom of your freezer compartment. Lubricate the rollers and tracks with a little wheel bearing grease. Examine the condition of each belt as described in section 2-5(a).


Make sure the power is off the refrigerator before disassembling any lighting circuit.On some bottom-evap models, you may have to remove some of the plastic moulding around the door frame to access some of the evaporator panel screws. Pump belt tension is explained in section 7-4.7-11 AGITATORMost Maytag washers have an agitator that lifts directly out.
These models have a rubber stop ring around the agitator shaft at the bottom of the splines.
This can usually be accomplished by placing a pan of very hot water in various places on the panel, or by blowing warm air on it with a blow-dryer. Therefore, when you are diagnosing a defrost problem, it's a good idea to try to avoid melting the ice encasing the terminating thermostat until you've made your diagnosis.
If the thermostat opens before you've had a chance to see if the heater works, you'll have to by-pass it. There are many styles, but most are variations of the three types pictured in Figure 20.Aback-evaporatormodel is one with the evaporator mounted vertically against theinside back wallof the freezer compartment. These may be bottom freezer models, side-by-sides (Figure 17) or top freezer models (Figure 18.)Abottom-evaporatormodel is one with the evaporator mounted horizontally (flat) beneath a panel on thebottomof the freezer compartment (Figure 19). Block up the tub so the tub remains in line with the cabinet. Beneath the washer, in the center, is the brake package.
Does it have a fluffy (snowy) white consistency, or is it solid and clear-ish or slightly milky white-ish?Check the frostpattern.
The brake package changes the machine from the spin to the drain cycle and back when the motor reverses.
It also brakes the spinning basket at the end of the spin cycle or when the lid is lifted. The brake lining is normally lubricated by a few drops of oil.
If the lining gets too dry, it can start squeaking at the very end of the spin cycle, when it is braking the basket. Or is it not frosted at all?On back-evap models, examine the drain pan directly beneath the evaporator. Is it clear, or is it filled with solid ice?Each of these symptoms indicates a different problem. YOU MAY HURT YOURSELF OPENING IT, AND IT IS IMPRACTICAL FOR YOU TO TRY TO REBUILD IT YOURSELF. BRAKE PACKAGE REMOVALRemove the center screw from the driveshaft.
If you have lots of white, snowy ice, keep reading.4-5 DEFROST SYSTEMIf the frost is snowy and white in appearance, you have a defrost problem. The three main components of the defrost system are the defrost timer, the defrost heater and the terminating thermostat.4-5(a) DEFROST TIMERS AND ADAPTIVE DEFROST CONTROLIn most older refrigerators and some newer ones, a motor-driven timer (Figure 21) is used to stop the compressor and initiate a defrost cycle.
This will help you to thread the brake package into the base plate without cross-threading it. With the tub blocked up, grab the bottom of the transmission casing and move it by hand until you can slip the brake package onto the splines. If you have a Whirlpool or Kenmore refrigerator with a flex-tray icemaker, the defrost timer is integrated into the icemaker.
If you don't, you will be trying to overcome brake pressure to turn the package.Turn the transmission and brake package until the brake package is hand tight in the baseplate.
This is true whether you are using the icemaker to make ice or not; it is running constantly to time your defrost cycles. If you have a defrost problem and you have one of these machines, follow the instructions in section 4-6.Nowadays, refrigerators are being made as efficient as possible, due in no small part to government energy efficiency requirements. Defrost heaters use a lot of energy, so designers are mimimizing the total amount of time that the heater is energized.
Such factors include ambient humidity and temperature, the water content and temperature of the food you put into the fridge, icemaking within the freezer, and how often the door is opened and closed.For example, if you go away on vacation for a week, the refrigerator door will obviously not be opened for a long time. While holding the transmission so it doesn't turn, run the drive pulley up as tight as you can by hand onto the helical shaft.You will see a drive lug on the pulley that corresponds to the shaft drive lug.
Less humid air will enter the fridge than if someone was at home, and opening and closing the door. Frost buildup will be much slower than usual, so the refrigerator will not need to be defrosted as often as normal.
It also will not need to be chilled as often, so compressor run times will be shorter and less frequent.Designers are using microprocessors (on solid state circuit boards) to adapt defrost intervals and durations to compensate for differences and changes in operating conditions.
Then turn the pulley gently clockwise until you just barely begin to feel the brake spring pressure.The shaft lug should be at about 9 o'clock from the pulley lug.
Such techniques are calledAdaptive Defrost Control, commonly abbreviated as ADC.To make decisions about the correct defrost duration and interval, the control board must have input about the conditions that the fridge is operating under. If not, adjust the shaft lug on the splines. The idea is to get the pulley to bottom out on the helical drive shaft just as the drive lugs touch. Each manufacturer uses a different logic scheme and different inputs, such as door open time, compressor run time, duration of the previous defrost cycle, and duration and intervals of door openings.Door open info is provided to the logic board by the door switch - the same one that controls the refrigerator's internal lights. If it is not correct, you will hear the drive motor bogging down and perhaps tripping on the overload during the agitation cycle.7-14 DAMPER PADSThe damper supports the weight of the water in the tub. For example, the ADC is programmed with a maximum amount of time that the heater can stay on; say, for 16 minutes. Mark the position of the nuts on the three eyebolts (Figure M-15) and remove the bottom nuts.
Often they are mounted under a cover plate or in a bracket that hides all but the advancement pinion.
This will remove spring tension on the tub centering springs.Lean the washer back against the wall at an angle. Place a 4x4 wood block directly underneath the transmission pulley and lower the machine onto the wood block.
The easiest way to recognize them is that the harness connection is always labelled with the compressor, defrost heater, L1 and L2. The easiest way to see the heater is to look for the heavy, rubber-coated wires leading to it; one on each end.
The element has no protective tubing and generally wraps around beneath the evaporator in a large "U" shape.You must exercise caution when handling these heaters to prevent burning yourself.
If that happens, you want to turn the heater off soon after the ice melts, to prevent the evaporator compartment from heating up too much.
If theterminating thermostatsenses too high a temperature in the compartment, it opens, and cuts power to the heater. The thermostat will then stay open until the compartment again reaches a very low temperature. In other words, it waits to reset itself until the cooling cycle starts again.If the evaporator is more heavily frosted, the ice may not all melt within the time allotted by the timer. The heater will stay on until thetimerstops the defrost cycle, and restarts the cooling cycle.If you initiate defrost (turn the timer on) and the heaterdoes notheat up, then usually the heater or terminating thermostat is bad.
If you initiate defrost and the heaterdoesturn on, then usually the timer or ADC board is bad, and you must replace it.To diagnose which component is bad, you must initiate the defrost mode, or test continuity through the defrost heater and terminating thermostat. Within ten minutes (usually much less) you should be able to see a red glow from the defrost heater(s), which is (are) mounted beneath the evaporator.If you have an aluminum-tube heater as described in section 4-5(b), it will not glow red, but youwillsee ice melting away from its coils. Timers can get old, worn and coked up with dust, and may develop hard spots in the bearings. If youdo nothear or see indications that the defrost heater is working, then it is necessary to investigate a little further. If you cannot tell for sure, get the information for your model fridge from your parts man. DIAGNOSIS: DEFROST HEATER AND TERMINATING THERMOSTATIf you do not hear or see indications that the defrost heater is working, you could be looking at one of several different problems.
The heatermaybe so icebound that it would takehoursfor the heater to melt enough ice for you to see the heater begin to work. If you hear the motor buzzing, but it doesn't start in either or both directions, test the capacitor (if any) and starting switch as described in sections 2-6(e) and 7-8. If they are not connected to a terminal block, you will need to cut the leads to test for continuity.
Make sure you're not testing continuity across the terminating thermostat too; it may be wide open above 40 or 50 degrees.
With glass-tube heaters, be careful that the glass is not cracked or broken and that you do not cut yourself. It's cheap.If you have an ammeter, try to determine if the heater is drawing any power before you melt any ice.
In trying to find the heater leads, be careful that you do not melt so much ice that the terminating thermostat opens. If you suspect that the terminating thermostat might be open, temporarily bypass the terminating thermostat with an alligator jumper as described below.If you cannot find the heater leads, an alternativeis to check the current in one lead of the main power cord. Double-check this diagnosis by jumping across (shorting) the terminating thermostat with your alligator jumpers. If the two thermostat leads are not on a terminal block, you will have to cut the leads to jump the thermostat. Remember that it's a wet environment.LIFTING THE EVAPORATORIf you have a bottom-evap model fridge, replacing the heater will involve the delicate task of lifting the evaporator up to get to the heater.
If you break or puncture one of those tubes, you're looking at a potentially expensive sealed system repair.Thaw out the evaporator as thoroughly as is humanly possible. Remove the evaporator mounting screws (if there are any) and gently lift up the end of the evaporator opposite the tubes.
Prop up the evaporator with a blunt instrument (I use my electrical pliers or a flashlight) and change the heater. Do what you went in there to do, but as much as possible, avoid moving the evaporator around too much.When you finish, gently lower the evaporator back into place. The hard tray is finished in a dark gray or black color and has rotating fingers that eject the cubes from the unit; the flex-tray has a white plastic, flexible tray that inverts and twists to eject, much the same as a manual ice cube tray would work. The hard-tray and separate defrost timer is by far the more common arrangement.This defrost system has the same components described in the defrost system in section 4-5, except that the defrost timer is integrated into the icemaker.
However, the actual switch that controls the heater is accessible.Remove the icemaker and the evaporator panel as described in section 4-4.
Take the plastic cover off the face of the icemaker and remove the three screws holding the metal faceplate to the icemaker head.
Plug the icemaker back into its electrical socket and observe the drive motor in the upper lefthand corner of the icemaker head. The defrost switch is the small, rectangular switch in the upper righthand corner of the icemaker head. Using electrical tape, tape it out of the way so it does not touch any other metal object in the icemaker head.
Using your resistance meter, you should see continuity (and no resistance) between the empty terminal (where the BLACK lead was) and the PINK terminal.You should see NO continuity between the empty (BLACK) and ORANGE terminal. When the switch toggle is depressed, continuity will be just the opposite: BLACK-ORANGE-CONTINUITY, BLACK-PINK-NO CONTINUITY. If the switch is okay, the problem is probably your defrost heater or terminating thermostat. Alignment of the gears is critical; follow the instructions that come with the gear sets carefully. If you replace the motor, you will have to re-align the defrost timing gear mechanism.RE-ASSEMBLYIf you have not removed the defrost timing gear housing from the back of the icemaker head or the motor from the front of the head, you will not need to re-align thedefrost timinggear mechanism. However, youwillneed to realign thedrivegear mechanism.Align the hole in the small drive gear with the alignment hole in the icemaker head and install the gear. If they do not line up perfectly, momentarily plug the icemaker in or apply 110 volt power to the two center leads of the plug This will turn the drive motor slightly. Lift the spring-loaded shut-off arm (ice level sensor) as you install the cam and let it rest in the cam hollow.
Carefully install the metal cover plate, making sure the end of the wire shut-off arm (ice level sensor) is in its pivot hole in the metal cover plate.
Make sure the icemaker is turned on (ice level sensor arm is down) or it won't make ice.4-7 HOT GAS DEFROST PROBLEMSIf you have a refrigerator with a hot gas defrost system, the defrost mechanism is somewhat different from those described in previous sections of this book. If you suspect that you might have a hot-gas defroster but you are not sure, ask your appliance parts dealer.
Most of these refrigerators were built before 1970, but not all.The main difference in a hot gas system is that there is no electrical heater or separate terminating thermostat.
The defrost cycle is controlled by a defrost timer similar to the one you'll find in electric defrost systems, but the timer controls asolenoid valveinstead of aheater. These units have a temperature sensing bulb, similar to that found on the cold control (see section 4-9 and Figures 21 and 33) as a part of the timer. Its function is to sense the temperature of the evaporator so the defrost mechanism knows when to shut off.Troubleshooting a defrost problem in this system involves two steps. Wait and watch your evaporator for 10-15 minutes.If the frost starts to melt, then your defrost timer has gone bad.
Thoroughly melt the rest of the frost from your evaporator and replace the defrost timer.If the frost doesnotstart to melt, then your defrost solenoid is probably bad. Fortunately, the defrost solenoid is usually designed so the electrical coil can be replaced without cutting into the sealed system. Trace the Freon tubing until you find electrical wires joining the tubing at a certain point. UNEVEN FROST PATTERNS, OR NO FROST AT ALLThe evaporator should be bitterly cold to the touch.
If the evaporator is either slightly cool or not cold at all, and your compressor is runningconstantly(not short-cycling; see section 4-9) you have a more serious problem. The same diagnosis applies if just the first coil or two in the evaporator is (are) frosted and the rest are relatively free of ice or perhaps even lukewarm.What's happening is that the Freon is not getting compressed enough in the compressor. This could be due to two causes: either the amount of Freon in the system is low, or the compressor is worn out. Itmayonly require recharging the Freon system, which, depending on the refrigerant used, may cost you a little, or a LOT. I have only seen one exception to this diagnosis, and this is described in section 7-2.Don't let the age of the refrigerator affect your diagnosis.
Not too long ago, one of the largest appliance companies put out a series of refrigerators with compressors that were either poorly designed or poorly constructed; I never did find out which. These were their giant, 20 to 25 cubic-foot flagship models, with techno-marvelous gadgets like digital self-diagnosis and ice and water in the door, and they were built with compressors that wore out within 2 years.Fortunately, the biggest and best companies warrant their refrigerators for five years or more, so these refrigerators were still covered under warranty. COLD CONTROLIf your refrigerator is cold but not as cold as usual, and you cannot trace it to any of the other problems in this chapter, your cold control may be defective. To test its cut-in and cut-out temperatures, you can try putting the capillary bulb in ice water and measuring the temperature with a thermometer, but it's a wet, messy, job and it's difficult to control the temperatures. The capillary tube is the liquid-filled temperature-sensing element of the cold control, and operates in the same manner as a thermometerbulb; in fact, the end of the capillary tube may have a bulb. The tube and bulbmaybe coiled right next to the cold control, or they may be led away to another part of the compartment.If you are justtesting(electrically) the cold control, you can jumper directly from one wire lead to the other. By doing this, you are closing the switch manually, and assuming the machine is not in the defrost mode, the compressor should start.If you arereplacingthe cold control, it will be necessary to trace where the capillary tube goes, and remove the whole tubewiththe cold control.
