Good day,

As you can see from above I have a GE JVM1190BY002 Microwave/Convection oven. This past weekend it stopped cooking via the microwave. I have found other posts online for this microwave that it could be (most likely) one of five things, i.e., the diode, magnetron, HV capacitor, thermostat, or door switch.

The exact symptoms are that the display, clock, keypads work fine. When I go to cook, the light inside turns on, the display starts to count down, etc., but BOTH the fan and the magnetron don't seem to be running.

When it first occurred it was after cooking carrots in water and that worked fine, but the next thing in didn't cook. When we let it set overnight it worked ONCE in the morning, but since then no luck at all.

This leads me to believe it's the thermostat. But given the age of the microwave, the fact that a new one would cost me over probably $1k, and the fact that if I have to take it down and repair it, why not replace the components that are most likely to give me grief in the foreseeable future.

So I'm looking for help in choosing what parts to purchase, say, just for preventive maintenance.

There are three thermostats on your site. I'm assuming the "Thermostat?Magnetron" is the right one to buy (PN WB21X536). What other parts would you recommend?

Thank you!
