My GE Microwave oven, blows the circuit after running for a short while

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.

My e-mail number is

Re: My GE Microwave oven, blows the circuit after running...

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.

We're happy to help and we appreciate your thoughtful rating of our answer.

My microwave blow the fuse after pressing start

There could be a bad interlock switch. I have seen this blow the fuse. The high voltage capacitor could be shorted. This will blow the fuse immediately. Take care around the high voltage circuit. Make sure you short the capactor terminals to groound before touching any connectors.

the panel display is fried. you'll need to remove and replace it...this the sort of thing you enjoy doing?

Keeps blowing breaker. have switched outlets (circuits), even exchanged for new one. HB-P100N30AL-S3

Possible that there is a short within , if there is sparking then the magnetron is defective. If not check for shorting in the capacitor, check the mains transformer or the secondary supply. Isolating the circuit will confirm which part produces the short. Please be careful when you work with the power connected.

Our GE built in microwave model # JKP62G suddenly started making a loud noise when we try to use it. It does this on any power level and on the defrost setting also. It does not seem to be heating...

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.

GE Spacemaker Microwave JVM1441 BH04 tripping circuit breaker

your power transformer for the magnetron could have a shorted primary power winding,the door safety interlock switch could be mis-adjusted,this normally blows the internal unit fuse,a shorted high voltage capacitor,or diode,a bare wire inside the unit,more than the microwave on that circuit or a weak circuit breaker in the house power panel

Hi, When my GE jvm1650bb microwave starts, it begins to work and then blows the fuse in the house. Does this every time, the circut is not overloaded. Is their a part that went bad that I can replace?

Try your oven on another circuit in your house. It is curious that your oven doesn't blow its own fuse before the house one. If it doesn't blow the fuse in the "new" circuit, check to see what is really on the kitchen circuit. It might, in fact, be overloaded. Good luck.

I have a J HP60G 002 GE Microwave (older)keeps

If it blows the line fuse instantly when you push start.... it is either a shorted HV capacitor or shorted monitor switch.... most likely.

Opening the door blows the fuse

more than likely you door safety switch has a short and every time you pull the door open the connections arc and trip the breaker or blows the fuse.

Fuse keeps blowing.

couple questions -
what else is on the circuit,
and what current does the oven need

there are whirlpool over-range models with
1200watts of microwave,
1500watts of convection power, a
60watt bulb and a
375watt fan

over 15amps -20amp circuit needed

if you inadvertantly replaced a higher current fuse with a 15amp fuse, it will blow every time.
the install guide reccommends 20amp
not a solution, something to check,

Unit Electrical Problem

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.
