When I open the door of the microwave the circuit breaker for the wall socket into which the microwave is plugged pops. This also happens if I have the microwave door opened with it unplugged and then plug it into the wall outlet. If I start with the microwave unplugged, and the door closed, then plug it into the wall and turn it on without ever opening the door it works fine.After reading a bunch of your problem diagnosis (and safety warnings) this sounds like a door or other interlock switch problem. I have removed the cover of the microwave, and know how to replace any/all of the switches. What I am not clear on is, if there is a bad switch in the unit, why would it cause a breaker to pop instead of just keeping the magnetron or the entire unit from coming on?I can't see any evidenc of any arcing or any burned smell on any of the wiring.
