Motor just hums after replacing drive coupler

It was starting the spin cycle when it began making a loud clicking sound. Using this forum, I found the solution was to replace the drive coupler. I heard the drain pump draining, so I know it's not the issue. While the coupler I noted the transmission shaft didn't turn, but thought perhaps the brake was engaged. After replacing it, I attempted to resume the spin cycle and the motor just hummed. It stopped when I lifted the lid, so I know the lid switch is working. The drum spins freely by hand in the counter clockwise direction but won't spin clockwise. When the front was off, I looked for anything between the drum and the tub, but didn't see anything. I can also move the drum about 2 inches vertically and changing the height seems to change the resistance counter clockwise but didn't do anything clockwise. Again, I'm not sure if the brake is engaged or not. With the lid up, and the lid switch pressed, I still wasn't able to turn the drum clockwise, and the motor still just hummed. There's no oil leaking from the transmission. Additionally, the agitator shaft turns freely both directions, when the dogs are out of the way. Is there a relatively simple way to ensure the brake is disengaged and see if it spins under power? To me it seems like it could be either the brake or the transmission. Any ideas?

SOURCE: Kenmore 80 series won't spin

If it is draining then the motor is turning the pump so it is ok.
This washer has no belt so that is not the problem.
Remove the cabinet and bypass the lid switch wires and put into a spin. Watch the clutch to see if it is turning. If the clutch housing is not turning and you know for sure the coupler is not broken then you need a new transmission. If the clutch housing is turning but the basket is not spinning you have something binding the basket or you need a new basket drive and clutch.
If you have only looked at the coupler from underneath you may not be able to tell if it is broken in the center. If it is broken again your transmission is not staying in neutral drain until the water is drained. That means it is going into spin with full load of clothes and water. This puts a lot of pressure on the coupler and causes them to fail prematurely. If this is the case you will need a new transmission.
Post back if you have any questions.

SOURCE: destroyed motor coupling

It appears your clutch assembly has failed in this instance.

For replacement parts - head on over to PartSelect.com or RepairClinic.com and enter in your full model number for a full parts listing.
I recommend both sites because ...


FixYa has no affiliation with either site - I have been using and recommending them for years - trouble free.

PartSelect has a great schematic database for locating the part on your unit and great "testimonials" for each part that often times includes HOW-TO information.
RepairClinic has pictures of each part they sell and also a great how-to and troubleshooting for basic repairs.


If your unit has never been serviced - there should still be an original service manual enclosed in plastic taped to the inside of the shell.
In the service manual are Error codes, maintenance procedures, and troubleshooting steps you can follow.


Anything too complicated or beyond your scope should be handled by a professional.

If you think you want to tackle the repair - and have gotten stuck on a step - reply to your question and I will be glad to help you out.

SOURCE: Motor does not turn in wash or rinse mode. works

Hi, well NO it's not the motor and there are no diodes inside the motor, thats not actually the way they in which they are made to rotate and reverse direction.
This is done by "Driving" the motor with a pulse width modulated signal, that makes the motor spin,as the electricity is switched from pole to pole the motor's stator is attracted to that pole and moves forwards or backwards depending on the direction of the waveform.
So whenever a motor isn't working, spinning, then most often if the motor works, as it actually appears your is OK, then the "Controller' is at fault. The controller in this case is the Main Controller Board. This must be replaced in it's entirety. If you wish to DIY, then please find below a service and repair manual, to use to try and track down exactly whats wrong...

service and repair manual above..
But you see these days, it is nearly always my professional opinion that one should always get a "Quote" from the manufacturers recommended service center,Anma in your case, please contact a local or head office and ask for a referral to an Authorised service center. I cannot stress how important that last point is. It is even worth the cost of shipping. You see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do i, that a replacement, with a warranty, is a better option.

The humming sound is coming from the drive motor running but unable to drive the agitator nor the basket to spin. The drive motor is definitely running as the drain function works because of the fact that drain pump is directly coupled with the rear spline of the motor. The drain pump works in either direction as long as the motor runs. The problem is obviously a broken motor coupler which transfers the mechanical energy of the motor to the transmission. The solution then is to replace the broken coupler. Click on the link below for the detailed step-by-step procedure in replacing the motor coupler.

Replacing Motor Coupler on Kenmore and Whirlpool Top-Load Washing Machines

Kenmore 70 Series Washing Machine Just Hums (Won't Agitate)


First, see the Sears Parts site for your washer:

http://www.searspartsdirect.com/partsdirect/getModel!retrieve.pd?modelNumber=110.22712100

Also see the Whirlpool / Kenmore service manual.

https://secured.whirlpool.com/Service/SrvTechAdm.nsf/2cd44500d572193285256a45004fd9d6/f7e2147fa98b28cf85257122007475cb/$FILE/L-55.pdf

Initial thoughts are a worn/broken motor coupler.

See the following for how to get to it and check it.

http://www.american-appliance.com/catalog/newsdesk_info.php?newsPath=16&newsdesk_id=135&osCsid=6019c5e82bfa177df953f5d6ebeac983

Kenmore / Whirlpool top load, direct drive washers use a "Motor Coupler" between the motor and transmission.

It's used as a fail safe device and consists of three parts.

Two of the parts are the same, plastic units with three prongs that fit on one of the motor output shafts and the other on the transmission input shaft. Between them is a rubber piece with six holes.

It's possible that the prongs have broken and the humming that you hear is the pieces rubbing against the center rubber piece.

The power from the motor is transmitted through the rubber piece to the transmission.

The other shaft on the motor directly drives the pump.

If the motor coupler is broken, or worn, the motor may not be able to send full power to the transmission for agitating or spinning.

See the following for how to remove the cabinet, pump, motor and motor mounting plate to inspect and replace the motor coupler.

http://www.american-appliance.com/catalog/newsdesk_info.php?newsPath=16&newsdesk_id=137

If the coupler looks damaged, it's a relatively easy fix.

Pry the plastic pieces from the motor and transmission. Some people use a claw hammer but I've found that using a small (6 inch) pry bar works well.

Carefully fit the plastic pieces over the motor and transmission shafts and press them in place (Use a 1/2" of larger socket to put pressure equally around the pieces.

Put the rubber piece on the transmission plastic piece.

Replace the motor mounting plate.

Carefully line up the plastic prongs on the motor based plastic piece to the three un-used holes in the rubber piece. If they don't line up right, the coupler could be damaged.

Mount the motor, don't forget the two screws, put the pump back on the motor and use its' clips.

Put the cabinet back on, don't forget to plug the lid switch back in and re-mount the console.

Whirlpool washer makes loud noise now won't spin


HI. The issue here will be with the actual motor coupler. It is damaged at this time. The clutch and coupler should be replaced asap.The coupler is responsible for transferring the rotative torque to the actual transmission(direct drive assembly). The clutch is a regulator. Once these components are replaced, the unit will operate properly.

Now. The actual parts cost will be $50.00. This includes the clutch kit, and coupler, as well. Total repair cost, if service is requested by a tech, will be $150.00, roughly.

Washer made loud noise after cycle began


Your coupler is bad and the motor is sitting there spinning inside the coupler. If you remove the case, take the two clips off the pump (You don't have to remove it, just push it out of the way). Then take the two screws out of the clips holding the motor. Un-clip the motor. One piece of the coupler is on the motor shaft. another is a black piece of rubber and the last piece should still be on the transmission. Replace this and put back together. This will fix your problem.

Motor is humming loudly.


Motors hum, and your right, it could be no worse than normal.

I would be suspect that there is a gear stripped in the gearcase, since this is a direct drive washing machine.

Reassemble the motor back onto the washer. Run it through a cycle manually (rotate the timer by hand) until the motor turns, then look to see if it's turning. If it is, or even more so, if it pumps water out of the tub, then it is probably the stripped out gearcase.

Reply with you findings and more advice.

Motor makes loud rattling noise during rinse cycle


could be the coupler and the only way to truely check it is to take the pump, then the motor off. But it seems strange to me that you say it works fine. Is it spinning? usually when the coupler breaks it sounds horrible and usually will not spin but it will drain.I would check the coupler again.

Ge wvsr1060a2ww washer does not spin or agitate


first look to see if this is a belt drive. If not look for a coupler(round black rubber piece with three holes, three plastic fingers from both sides going in it) from the motor to the gearcase. The motor sit between the pump and gearcase, it will pump out, but not spin.

No belt on your machine. Sounds like motor coupler that joins motor and transmission is broken. Very inexpensive part but a few steps involved in getting machine disassembled Look up YouTube video on replacing motor coupler on Whirlpool washer.

Loud clicking noise at spin cycle


It sounds like you have a motor coupling that has gone bad. Most of the Kenmore top loaders that I'm familiar with are direct drive machines. Which means, they use a motor coupling between the electric drive motor and transmission to run. If you are in the habit of doing heavy loads like comforters, blankets and jeans this can put a heavy burden on the motor coupler and wear it out faster. The coupler is designed to take the burden of the punishment in order to protect the transmission and drive motor and it is common for them to wear out. The coupler is fairly easy to replace and usually runs about $15. It is located inside the machine between the drive motor and transmission under the wash tub. You would have to remove the outside machine casing, the water pump and drive motor to get to it, though. Make sure the machine is unplugged before attempting any repairs involving removal of the drive motor. If you are not mechanically inclined, you may want to seek the aid of a repairman. I hope this helps.
