I have a Whirlpool Washer/Dryer Combo (Model LTG6234DQ1) that makes a loud "screeching" noise during the spin cycle. Does anyone have any suggestions as to what may be causing this problem?

Thanks!

PS: The machine is about 10 years old.

Does it come up to speed while spinning?
Could be a brake dragging.
Remove the motor from the transmission and run the motor in spin mode to eliminate motor bearings as the noise.

Have you removed the front panel and had a look yet? That sounds like a broken coupler to me ==> http://www.repaircli...mber=LTG6234DQ1

Is there a diagram showing how to take the machine apart? I've taken my regular washer apart, but never this "combo" one.

Thanks.

OK - I finally found the time to get to this (don't worry - there are two washers in the house so I'm not in too much trouble :sillytongue: ). I took the front panel off and checked the coupling, but those parts were fine. I turned the coupling piece that is connect to the washer and I heard a squeal. There is a round piece directly under the tub, and inside that is a spring of some sort. It appears that the spring is resting on the round piece and making the squealing noise. I don't know if this is what is causing all of the noise, but I took a video of it as I turned the coupling by hand. Let me know what you think.

Thanks!

Looks like possibly the thrust washer c-clip has broken and let the basket drive/brake assembly drop down too far and now the clutch is rubbing against the brake springs.

You will need to pull the transmission and check the thrust washer and c-clip on the agitator shaft and make sure the the brake release lever isn't broken also.

OK - I finally was able to get to the bottom of the washer (it is located in a very small second floor laundry room) and pulled the transmission. Unfortunately everything appears to be intact.

Have you raised the lid while it is agitating and verified that the agitator is actually moving back and forth?

Do you get any of this noise in agitate at all, maybe the same noise but a little quieter? If yes, maybe something stuck in pump and in agitate it pushes it back out of the pump so the noise doesn't happen and in spin it sucks it back in. Pull the pump away from the motor and start a spin cycle and see if you still get the noise.

Also, in the spin cycle is the tub actually spinning while it is making that noise?

Did you check both halves of the drive coupling to make sure the centers are not stripped out? The transmission side should be OK since you were able to turn it by hand and the clutch moved to make a squeaking noise that didn't really sound like the same sound as the first video. The first video sounds like a stripped out drive coupling letting the motor run free without any kind of load on it, (check the motor half of the drive coupling and make sure it is solidly attached to the motor, doesn't have the center rounded out or a crack that would let it slip with the load from spin).

You can't check the coupler while it's still installed-- you have to remove the motor so you can inspect the two plastic pieces because they can crack and still look okay. BTW, the new couplers now have a metal insert to mitigate this very problem.

I'm betting I called the ball on this one in Post #4:

did you check try removing the pump from the motor shaft and then put it in spin? I think the sound is coming from the motor side of the transmission, based on the speed of the noise{does that make sense} just try it.

Have to look there; I'd be very surprised if this isn't the problem.

Speaking of problems those metal inserts make the coupling a bear to install. You have to whack at it with a hammer - the last thing I want to do to a machine. If anyone knows a trick, I'm all ears.
First, do no harm.

I've ordered the coupler. I'll let you know how it goes once I get it.

Thanks!

If this was the noise I heard during diagnostics, I would look at removing the drain pump and then put into spin............ It could be an item rubbing on the pump impeller...............To me, the pitch is too high to be a bad drive coupler.......................A lower, mechanical, spinning, clicking sound, I would look at the coupler.....

Okey doke - I got the part and installed it. The original drive couplers looked OK, but I replaced them anyway. Right before I put everything back together I checked the pump as suggested above. There was a bobby pin stuck in there and I pulled it out. Once I put everything back together I started it up and lo and behold no noise! Bobby pin? Coupler? Hmmm ...

Many thanks to all who helped me out with this! (oh, and my Mom thanks you too! :thanks: )

Beer money on the way!!

May have been the bobby pin but no harm in upgrading the coupler to the new steel hub type!

I used to have a dairy farm customer under MA that would get these metal clips from the milking machines in the pump at lest once a month I usually got a bottle of real milk out of the deal. Boy was I pissed when they cancelled their Maintenance agreement.
