Mod # 110.20994993 ser# CL0501245 The motor pulses on and off in spin. It will start but as soon as it gets up in rpm it shuts off, it will try to start as soon as rpm drops. I replaced the switch on the front the motor, and the speed selector switch, it still does the same thing. Another servicer replaced the Motor and timer and that didn't fix the it. I don't have a wiring diagram for this washer. Please help

Does the Motor get up to speed ? It could be a bad Speed Selector Switch. Have you tried it with different Speed settings ? 110.20994993 Tech Sheets

Think my first reply went lost in cyberspace. A loooooooong shot - could the lid switch be juuuuuuust making contact? A meter or test light on motor run windings to see if power stays or not , or various switches to check for power when running. Have fun - popcorn optional...

Good thought, grey one! I've run into this myself on rare occasions. I've seen a situation where when the washer gets up to high-speed spin, the vibration is just enough to cause the lid switch plunger to lift and lose contact with the lid switch actuator. Bimbobway, you can test this by jumping out the lid switch so that it's always closed and then run the washer.

Yes it works perfectly in agitate and on all 3 speeeds. I have bypassed the lid switch. It still does the some thing. I have tested it with the motor off of the mount and it still does it.

A video is a good thought, might give some other insight. Only other thing I can think of is a failing centrifugal switch In the motor, one of the contacts might be coming undone during spin. It's a long shot; I'm reaching here!

i have found loose run winding wire frequently does this.... so the start winding kicks the motor.... the switch connects but there is no power on the run winding to maintain it... so it slows down and starts all over again... it basically sounds like whamp-click whamp-click etc etc.

Wow! , you have a good one here. I can hear everyone's mind turning way up here on Vancouver Island. I am just thinking out loud so don't take me too serious : the motor uses the same connections for running either ag. or sp. once the start winding decides which direction it rotates.I realize most of the parts have been changed , so the only(?) thing diff. between ag. or sp. is the by-pass. Timer was changed , so I would check wire - it may show continuity , but only with 2 or 3 of the strands. Is the power steady to the motor run windings when in spin? Sorry I am not much help , but geez - I am retired...

I got it! Yahoo! It pulses because only the start winding was working, it would pulse on and shut off because the centrifical switch shuts off the start winding. So I checked the run winding and there is 120 VAC going to them but there is no Neutral. I traced it back to the timer, replaced the timer again and now it works, I put the old speed selector switch back in and it quit working. It will only work with the 2ed new timer and the new speed selector switch. Strange very strange

That is pretty rare, good job. The key was that it did it when the motor was unmounted. Almost couldn't be antything else. Now if the motor had still been connected to the tranny and pump, you can get those exact same symptoms from the unit having partially frozen water in it as well as just the right size obstruction between the tubs. Just for future reference.

It's happened to me on a few occassions where I find the wires going to the motor up to the control panel either get loose or get pinched.
