My microwave will not heat, the turntable will not turn. I can select a cook time and press start and the micrwave will go thru the complete cycle, but will not heatup. What could be the prblem here. I have tested the door switch and they tested fine. Could it be the main control board. Any advice?.
Since you tested the door switches (my number one suspect) I would think you have a bad relay or a bad connection on the control panel circuit board. We repair these nationwide for $32.50, which is usually economical for most models. Just to make sure you have checked the door switches thoroughly, you can find my helpful text file called "doorsw.txt" via a Google search. It has important safety information and tips.

Any thought on where i can get the main board repair.
after carefully testing the door switch, found one of them had burn contacts. Replaced both door switches and the mocrowave is now working fine.
