Question about GE JVM1650 1000 Watts Microwave Oven
Thanks for your help! First the switch for these lights failed, and I just kept the lights on all the time. Then I was changing a bulb, and I didn't think to cut power at breaker. The light bulb flashed in my hand and burned out the whole lighting system. The other functions of the machine all work normally. I have opened the housing to look for burnt fuses/wires and found nothing. Thanks again for advice!!
This looks like a new entry as opposed to a reply, so I don;t know what advice you got or from whom.
But based on your problem, I'd say I know your problem.
We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid.
This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.
This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.
