The microwave does not heat up, and the turntable doesn't spin when you turn it on (although the fan engages.) When I open the door, the turntable starts to spin. Any idea what could be going on? Thank you.

My 19 year old microwave, intermittently, will turn on when the door is closed. The light/carousel go on but the heating element will not. It can go a day or two and act normally, then all of the sudden it will turn on (not heating element). Other than that it works fine. If I close the door with food in it, the carosel/light will go on before I enter a cook time, etc. It allows me to enter the cook time and operates properly until it times out, then the carousel stays on until I open the door. I'm thinking it is one of the secondary switches? Thanks!! Bill

Latest Questions

I have just finished repairing a broken plastic lever (part nr. 8205451). I am now reinstalling the control panel and the latch board. My problem is this: I do not see where to position the upper Door Interlock Microswitch. The other two microswitches (the lower Door Interlock Microswitch and the Monitor Microswitch) have identifiable brackets. There doesn't seem to be a bracket for the upper one within the latch board (part nr. 8185271).

My turntable will occasionally continue to run after the preset cooking time has completed. It will stop once the door is open, but will continue upon closing the door. The only way to turn it off is at the breaker. Everything else works great. Please advise for a possible fix.
