Hello:
Our Whirlpool direct drive unit works sometimes, but when it doesn’t, nothing works. It won’t agitate, pump, or spin. The motor does make a sound as if it is trying to turn. It will sometimes run normal and then all of a sudden lock up. If we let the motor run long when it’s locked up, we can detect a slight burning smell.
We replaced the switch first and then we replaced the coupler. The old coupler looked good, but nothing changed with the new. Now I opened it back up and hand turned the pump and it turned okay. I also turned on the part between the transmission and the bottom of the tub and it seemed to turn okay.
What do you think the problem might be?
