Question about GE JVM1630 Microwave Oven
This was not happening for a long time and all of a sudden it started doing this. It blows the whole circuit in the kitchen. I noticed that the when it was running the power seemed to go up and down.
I have shut the microwave down until a solution is found.

I sent you private e-mail.
Door switches or problems with wiring or the breaker, or something esle on the same breaker (a "no no") are the most likely problems.

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.

If it blows the fuse as soon as you hit the START button, it's almost certainly a shorted high-voltage capacitor.
If it blows a few seconds after you hit the START button, it's probably the high-voltage transformer. You'll possibly also smell a faint electrical burning smell from the rear vent after you shut if off.
Microwave can be very dangerous so it is best to have it looked by a professional
Would appreciate a solved rating for expert advise.
