Question about GE JEM31 Microwave Oven

1 Answer

No heat My GE JEM31 microwave (manufactured in NOV 2003) is not heating anything. The light goes on, the turntable moves, but no heat. It doesn't seem to be making any strange noises. Is this something I can fix? Or do I need to get service?

    Purchased JEM31 Nov 2006. Unit manufactured Aug 2006. Never had a problem until unit stopped heating. Received error while baking potato using SENSOR COOKING pad. Turntable oK. Oven light oK. Placed glass of water on turntable for two minutes using TIME COOK pad and received SENSOR ERROR. There was no heat in both attempts.

It is most likely a door switch, or a magnetron with a loose connection or a failing magnetron. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: You can find helpful exploded view diagrams and order parts by entering your full model number (without the suffix) here: If you still need help, please write back letting us know what you checked and what you found.
