Microwave has stopped working - plate no longer turns and microwave is not heating. I've seen other postings where the door switch was the problem. Is there as way to bypass the door switch so that I can be sure this is the problem?

Re: Turntable not turning and microwave not working
The switches are on the left or right side or both (there may be two).locate them and theres 2 wires on the switch.jump them out.if there bad replace them as it would be a hazard issue for radiation not to.

The wave emitting part inside the microwave oven is called the magnetron. The waves emitted by the magnetron generate heat in food. When the microwave is running, turntable turns and light comes on but there is no heat it means that either the magnetron is faulty or the magnetron is not getting power. When the magnetron is not getting power parts such as the high voltage diode or capacitor must be tested or replaced. Testing and repair must be carried by a technician.

Usually this is a bad turntable drive motor in the floor of the microwave but the only way to know for sure is to do some electrical testing with a volt/ohm meter and the wiring diagram located within the appliance.
I fixed the problem with my microwave turntable motor without having to replace it. I removed the motor from the microwave and placed it in a small vise. Using a very small flat head screwdriver I was able to pry up the four tabs holding the casing together. You may need a slightly larger screwdriver after that to bend them back out of the way so you can remove the motor cover plate. Carefully take out all the plastic gears and note their position for re-assembly. You will find that the primary gear, at the bottom of the rest of the gears is attached to the motor magnet. It has a shaft that acts as a bushing passing through the center motor magnet. On the underside it is attached to a plastic washer. This is where it breaks. The motor magnet spins free of the gear/bushing/washer assembly. I used JB Weld epoxy to glue this assembly back together and it works like brand new. Note: On mine there were four indentations on each side of the motor magnet which corresponded to little ?bumps? on the underside of the gear on top and washer on the bottom. Place all the plastic gears back into the motor in the correct order, slide on the motor cover plate and use a small cold chisel with a round end and tap hammer to bend the tabs back into place.
