Hi,
There is a short internally in the microwave...the fisrt place to look would be the high voltage transformer, but realistically it could be a rubbed through wore or even the capacitor shorted out...
The best way to check would be to start ohming out everything till you find the short and then fix it...
Just make sure you discharge everything first or you will blow your meter...

Hi,


Circuit Breakers do weaken over usage. It is not usually a time factor as much as a load factor. Each time a circuit breaker trips, it loses its ability to carry the same load as it did previously. In other words, a 15 amp breaker only carries the ability to carry 15 amps once. I recommend replacing the circuit breaker with one that has a matching rating. If you do feel up sizing is necessary, check the load rating of the appliances to make sure the additional size really is necessary. Increasing power to appliances that shouldn't need it increases the risks of potential electrical fires and masking real issues. Try changing it with higher amp breakers.



Please accept the solution if it's helpful. Do get back to us for any further query.

Thanks for contacting fixya.com

Hotpoint model 6671P convection microwave keeps tripping mains panel Fuse when start is pressed. Could this be a problem with a fuse in the Microwave or is is a dud magnatron? How best to test?


Too many watts on same circuit. Plug it into a different outlet and see what happens, not on same circuit. So one that stays live when micro trips circuit breaker.

Breaker trips when using microwave. Electrician can't find electrical problem. Could it be the microwave itself?


Answered earlier, another tips is to disconnect the power to the board and see if the circuit breaker holds, if not check the main line circuit.

Trips electricity


I would check out your breaker at your box . See what amps it is rated and see what your microwave is . Also your micro wave should only be on 1 breaker with nothing else on it

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

I'm sure the magnetron overheated and tripped the magnetron's thermal cutout.

I'd strongly suggest taking it back if you can.

The circuit breaker to the micro wave was tripped and when reset the microwave did not work it just hums also the lights and fan does not work. What's up with that?


the hi voltage transformer is still operating, but the rest is dead, you could remove outer cover and see if there are 2 fuses, most only have 1 fuse, sounds like new microwave time
