If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

R-9H84B. It just stopped working.Went to use it and nothing , thought it was unplugged. Repair man replaced the 20 amp fuse and it immediately blew. He said it was the transformer.Is it transformer?


It could be the transformer. Is it generating any smoke? They usually burn up because of shorted windings.

If the fuse blew, however, when the door was opened or closed, then you have a bad door switch.

If the unit heats, and the fuse blew after a few minutes, then you could have a weak fuse holder.

WHAT WILL MAKE MY GE MICROWAVE WES1384SM2SS FUSE KEEP BLOWING I REPLACED IT ONCE AND AS SOON AS I OPEN THE DOOR IT BLEW AGAIN


The fuse is there to protect your home in case something has gone wrong inside your microwave. Since the fuse has blown twice, you can safely assume that there is something wrong inside. It may be fixable, it may not be economic to fix it. Impossible to troubleshoot electronics without the unit and test equipment.

Has stopped working. light gone off at same time. plug fuse has not broke. any ideas ?


There is a fuse inside the microwave also.It is a ceramic fuse,usually 15A.It has to be replaced with another ceramic fuse of the same rating.Bear in mind,the fuse blew for a reason,so if it is the interior fuse replace it after a search for a fault.

After plugging it in, the microwave made the normal noise and then the light went out and nothing works. No power to the unit. Are there any fuses that could be blown? Or is it toast? Thanks, Steve


Hi,

How microwaves are designed, this problem would be a door switch issue and a blown fuse. If this unit is new and under warranty returning as a DOA. If not find a friend to open the unit and look for a bad switch alone with an open fuse at main power supply.

Good Luck

Microwave blows fuses


A short likely in the wiring for the light or at the safety switch embedded on the side where the door closes----be careful as a 20 amp fuse takes something major to take out.
(for it to blow)

This might be best left to a qualified service person.

Jenn-Air Microwave - no power


Had the same problem. Removed the unit (snapping off the upper and lower trim rings was a chore but they do snap off) and tested the power. Plug behind the unit was good. Pulled the cover and checked the thermal fuse with ohm meter. No good. Replaced fuse, microwave would run for a second, then light goes dim and it buzzes, then it blew the fuse. Per above suspected Capacitor. Changed that, and we are back up and running. Thanks!!

I have a goodmans microwave. a few weeks ago i opened the door and it blew the fuses. i have changed the fuse in the plug but still no power going to unit, please can u tell me if there is any fuses...


Firstly check the light.

As the light comes on when the door is opened - this could be the cause.

If that's ok, you could open it up to check the condition of the wiring, and that the door interlock is functioning.
As long as you don't damage anything, or remove the magnatron you should be fine.

I don't think there are any other fuses inside this model.

If it's anything else I would not attempt repair.

Double check that all is secure before using again - and turn off BEFORE opening the door each time.

sound like the door monitor switched has blown or shifted out of position if the switches dont operate in tandem when door is opened or closed it will blow the 10 amp fuse and kill the display they will need to be checked by engineer if it is monitor switch they are not expensive to replace.

No Power Whirlpool MH7140XF


does it not light up at all? A microwave has a fuse on it. Probably accessible from the back panel. if not you would need to disassemble it. Most likely cause of this is slamming the door broke one of the safety switches the door has so the microwave knows when the door is open. And it shorted against something when it broke. It might have simply blew the fuse but then again you might have fried it.
