Re: Our GE JVM153SH microwave continues to blow the...
If the microwave is not on a dedicated circuit, it's just the additional load the microwave is adding to the circuit which is causing the breaker to trip.

Cause 1 If too much current passes through the microwave circuitry, the line fuse will blow. If the line fuse blows, the microwave won’t start. To determine if the line fuse is at fault, use a multimeter to test it for continuity. If the fuse does not have continuity, replace it. In addition, you should investigate and resolve the problem that caused the fuse to blow. If you don’t resolve the underlying issue, the new fuse will blow too
Cause 2
Main Control Board
The main control board might be defective. However, this is rarely the case. Control boards are often misdiagnosed—check all of the more commonly defective parts. If you have determined that all of the other components are working properly,replace the main control board.
Cause 3
Thermal Fuse
The thermal fuse cuts off power to the microwave if the microwave overheats. To determine if the thermal fuse has blown, use a multimeter to test it for continuity. If the fuse does not have continuity, replace it. The thermal fuse cannot be reset—if the fuse is blown, it must be replaced.
Since its a electrical isue cal a liscenced professiona to resolve the issue . Your microwave oven isnt at fault . I belive the supplay to it has issue and would have blown anyway.
If you know DMM then only you can fix it. Check magnetron continuity and the transformer continuity. Mostly magnetron blows up.
Danger microwave has 5000 volts in it
Thanks

The door switches are slightly out of alignment. If you run the microwave and shift the door up or down, the micro might begin working.. The control panel must be removed and the door switches adjusted. I would not suggest you doing this yourself, as it may affect the microwave leakage through the door gap.
I had GE look at the problem today (my microwave is less than a year old and under warranty). He replaced the cam louver and that seems to have fixed the problem. This is a small motor accessible by removing three screws and the active vent door. The whole visit was less than 15 minutes.<!-- from fixya rte -->
F3 Shorted key panel (touch pad). 1. Will occur if a shorted key panel is detected continuously over 60 seconds. 2. Replace key panel (touch pad). What you can first try before replacing the keypad is first unplugging the microwave. Then you can get access to the panel by first removing the top grill and then unscrew the top of the control panel. There is a strip that looks like tape which attaches to the control panel which you need to wipe off and then blow dry. may not work the first time but be patient. also clean the bottom of the door and the latches to make sure the connection is clean. After that is should hopefully work without replacing the touch pad. Let me know how this works out for you. Benjamin
Could be the fuse inside the microwave is blown. You will need to unplug the microwave and remove the front control panel. Inisde the microwave housing you will need to trace the electrical wire coming into the unit. Usually you will find the in-line fuse located on the black power wire. You can pull the connectors off the fuse and test it with a continuity tester. If the fuse is blown replace it but make sure you use the same amp rated fuse as you removed. If the fuse blows again then there is an electrical short somewhere in the microwave.
you can check the ceramic fuse which sits above the control panel. it could be a 15 amp or a 20 amp. you should have continuity if you check it with an ohm meter. if not, replace it, but if it blows again you have another issue with the oven and will need to get it diagnosed.
The control panel module is different from the membrane. Unfortunately these modules themselves are usually very expensive, perhaps 1/2 the cost of a new microwave.
HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.
(((The fuse is located inside the unit along side the magnetron)))....
