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.
