This microwave runs fine sometimes and then others it will start and then completely shut off, come back on, and restart all by itself. I'm assuming one of the control boards is bad just don't know which one. Any ideas?

Answer Hello Mike. Check and make sure the door switches W10211972 are working properly on the unit. If not, it can turn on the fans and shut the unit on and off. If they are good and the cams are good, you may have a bad control board 8205533. Hope this helps.
Fan occasionally wants to "start" ~ sounds like a groan as it slowly starts up by itself, but then just dies... can't really tell when it will happen. Will replacing Part AP37788671 solve the problem? If not the correct fix, can you suggest another?

Answer Hello John. No, based on the information you provided, it sounds like the fan motor W10114253 is bad and will need to be replaced. It has power coming to it, but the motor is bad and does not run. You will need to replace the fan motor. Hope this helps.
