Hi there, I have a Kenmore Elite microwave that recently started tripping the breaker every time the door is opened when running. If I stop the microwave, THEN open the door it does not do it. Ideas?

They use a lot of power and should have it's own outlet, try plugging it in to the same plug as refrigerator, it's a double circuit and will have the power to supply both units, there should also be another plug in kitchen that is double circuit, keep trying different plug to you find it..
double circuit means top has 1 breaker and bottom is on another breaker

SOURCE: Microwave works with door open

If the top is open, the upper door switch should be open and the high voltage section should not be energized. That's the way it's *supposed* to work. But that buzzing is worrysome! Does the turntable turn during this condition? Does the inside light come on? How about the fan? If not, then I would doubt that it's cooking. If so, some models will do this. It's not uncommon to notice that the fan and light will try to come on for a split second when you shut the door. This would not indicate a problem. It has to do with the timing of the door switches and a replay on the board. If it's still under full warranty, it wouldn't hurt to call a GE-authorized servicer.

SOURCE: Microwave runs when door open

This is probably a a bad door switch or door switch mount. Chances are only the fan and light are running when you open it, but better safe than sorry. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure but not the only one. I have a text file called "doorsw.txt" which helps in diagnosing and repairing door switch problems, and a file called "safety.txt" which is of vital importance. You can find these files by searching at Yahoo.com (not Google) for this: microwave display safety.txt If you still have a problem, please write back with more detail. Be safe!

SOURCE: 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.

SOURCE: kenmore elite microwave oven displays "Locked" and will not respond

My Kenmore Elite microwave (don't have the model number in front of me) also mysteriously locked its own keypad (we were sitting in an adjacent room, heard a strange beep, and got up to find the LED reading "Locked."). I pressed and held down the Stop/Clear button for ~10 seconds and it returned to normal.

Kenmore Elite Microwave 721.79209010 Open Door and Microwave starts running;

Yes, a bad door interlock switch would cause this; either the top switch or the bottom switch. (The middle switch is called the Monitor switch. If it were bad, you microwave would blow fuses as soon as you press Start.)

Magic chef microwave MCO153UBF When I open the door the microwave trips the breaker. Turning on the breaker, I can run the microwave but as soon as the door is open it trips the breaker again.

Sounds like you need to replace the door switches the part number for this is 99002254. To gain access you must take the control loose. Be sure to unplug the unit before starting any work. I attached a link that may help you.

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 pops breaker on start

You probably have either a shorted high-voltage capacitor, or a shorted high-voltage transformer. And there is a 3rd possibility that should be checked first - the so-called "monitor switch" may be stuck in the closed position. There are usually 3 door switches in most microwave ovens, although some have 4. The monitor switch is usually the the one located in the middle of the door latch area.

Kenmore elite microwave 721.80833 stops cooking intermittently

Check the door switches if one is bad it may think the door is being opened and stop the unit from running. If it is from a bad connection it will get worse as it gets hotter while running.

Microwave doesn't start but the interior light goes on when you hit the start button

Hello

Remove the plug from the wall outlet and wait about 10 seconds before re-inserting it. The plug must be firmly inserted to transfer electricity to the appliance.


Open your home's circuit breaker box and reset the breaker if it has tripped and is set to the "Off" position. Simply slide the breaker over to the "On" position to fix a breaker that has tripped.


Plug a different appliance into the same outlet to make sure the outlet you are using is functional. Plug the microwave into a different outlet to see if this yields different results.


Press on the microwave door to ensure it is completely closed. The microwave will not function until the door is fully shut.


Press the "Start" pad on the display panel after setting the time. Failing to press this will result in the microwave not knowing that it should start.


Press the "Stop/Reset" pad on the panel if a program different from the program you want to run has already been entered into the system.


Press the "Clock" pad three times to turn off the demo mode. The demo mode will not allow the appliance to turn on and cook as it should.

No power

The door switches are designed to prevent the unit from running while the door is open. You probably have a blown fuse, and it's a white or dark grey ceramic fuse of 15A or 20A, available from local big box stores or appliance parts stores. The fuse is usually located on the floor of the chassis behind the control panel, or mounted in the same area as the door switches. Also, I'm really curious how the door switch got stuck while cleaning? That sounds scary...
