Microwave fan comes on when door is opened. Keeps tripping the breaker

Whenever the door is opened, the light AND fan come on. The fan shuts off when the door is closed. It keeps tripping the cuircut breaker. It blew the fuse in the microwave early on, as well. This is a 16 year old unit, so if i can't fixt it myself cheap, I'll probably scrap it. What could the problem be?

This is usually caused by either a bad door switch, a loose door switch mount (which are pretty simple problems to fix) or occasionally a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

You can find helpful exploded view diagrams and order parts for some brands by entering your full model number here.

There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

How can I stop my G9115SL microwave from tripping my circuit breaker?


I run into this problem when people are running their microwave off a 15amp line. Especially if it is sharing the line with another appliance like a refrigerator or large over head light or in my wife's case...the vacuum cleaner. Step one is to count the amps on the line. Step 2 is to replace the breaker. They do go bad but not often. Good luck.

Microwave keeps tripping circuit breaker


Chances are you have a shorted "monitor" interlock switch, or its mount is broken.

See this door switch help file.


You can find links to helpful exploded view diagrams and part ordering help here.



To give you more specific help, we would need the brand name and

full model number of your microwave.

GE microwave (Model JE2160SF03) trips breaker when door opened


Remove the control panel, take pictures of the door switch wiring while they are still connected to the door switches, then remove the door switch assembly. Have someone at the appliance store check each switch and repair the ones that are defective.

I purchased a switch for $7, reinstalled the door switch assembly and the microwave is working fine now.

I would suggest you check the door switches inside the microwave oven just below the keypad, rectangular in shape. The switches are normally open or closed, set meter to ohms, unhook lead from one side and test with door open and closed. If readings are the same both ways the switch is defective. "check all switches"

Be sure to keep this oven unplugged or the door open until it is fixed. If it runs by itself, this is a fire hazard.

First listen carefully for a buzzing sound behind the control panel when the door is shut.

If it's present, chances are you have a failing capacitor on the control panel assembly, which can be repaired for $39.95 in most cases. Details are here.

If that or a louder buzzing is only present when you have the door closed, then the oven is cooking when it's not supposed to, but the cooling fan is not on, and it is overheating and tripping the breaker.

That would be due to a shorted cook relay on the control board. That can also be repaired with our $39.95 service.

The odd characters on the display concern me separately. This could mean you have a noisy or otherwise failing magnetron.

If the display is fine when you're cooking properly with it, then the magnetron is probably okay.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

You probably have a bad door switch or door switch mount. See this file.

I'd suspect the interlock monitor switch is stuck, or its mounting bracket is out of adjustment. This is designed to blow the fuse if you try to run the oven while the door is open. The switch is supposed to open when you close the door. This switch is replaceable, but you should have this oven repaired by a professional. There are lethal voltages present with the cover off, and the possibility of microwave leakage is the repairs aren't done correctly.

Tripping of circuit breaker


Check what other appliances are on your circuit. What goes off when the breaker is tripped. You may need to relocate the microwave to a different circuit. Try to stay away from the refrigerator or AC circuits.

1800 XL JVM1860BD - won't work


It sounds like your controller may be failing. Or it could be an electrical line problem. Any other electrical itmes giving you trouble? Has anyone measured the voltage level of your power line? It should be around 110-125 volts AC. If it's significantly lower or higher, you may have a bad connection in your breaker panel or in the wiring leading to the home.
