Would it matter if the microwave was running when it stopped?
Answer Hello John. A door switch can go out at any time. I would test these first. Thanks.
I checked the door switch and the light goes out when I shut it. What else could it be?
Answer Hello John. Did you test all the door switches? You will need to test all three switches with a multi-meter to make sure they are good. NC should read closed and NO should read open. When the micro-switch is pressed, they should read reversed. Thanks.
