Question about GE Spacemaker JVM1640SJ Microwave Oven

1 Answer

Circuit breaker continually trips immediately when used

My JB1640WB microwave trips the breaker when any button is pushed. I have added nothing to the electrical and the microwave is on its' own circuit. It is on a 20 amp circuit which should be plenty.

Any suggestions?

When using the oven portion of the microwave oven it continues to trip the circuit the microwave is alone on a 20amp circuit .When I microwave it doesn't trip at all.Is it possible to move up to a 30 or 50...


If the breaker is an earth leakage type, it is possibly an earth leak problem which could be caused by insulation breakdown on the heater inside the microwave.
I would consult an aporved electrician for advice.

Machine will not turn on


from online Microwave Repair Manual: Totally dead oven (no lights, no clock, no display, no fan, no heat...)First, check power to the outlet using a lamp or radio you know works. The fuse or circuit breaker at your service panel may have blown/tripped due to an overload or fault in the microwave oven or some other appliance. You may just have too many appliances plugged into this circuit - microwave ovens are high current appliances and should be on a dedicated circuit if possible. If you attempt to run a heating appliance like a toaster or fryer at the same time, you *will* blow the fuse or trip the circuit breaker. A refrigerator should never be plugged into the same circuit for this reason as well - you really don't want it to be without power because of your popcorn!

If you find the fuse blown or circuit breaker tripped, unplug everything from the circuit to which the microwave is connected (keep in mind that other outlets may be fed from the same circuit). Replace the fuse or reset the circuit breaker. If the same thing happens again, you have a problem with the outlet or other wiring on the same branch circuit. If plugging in the microwave causes the fuse to blow or circuit breaker to trip immediately, there is a short circuit in the power cord or elsewhere.

The microwave oven may be powered from a GFCI outlet or downstream of one and the GFCI may have tripped. (Removing a broken oven lamp has been known to happen.) The GFCI outlet may not be in an obvious location but first check the countertop outlets. The tripped GFCI could be in the garage or almost anywhere else! Pushing the RESET button may be all that's needed.

Next, try to set the clock. With some ovens the screen will be totally blank following a power outage - there may be nothing wrong with it. Furthermore, some ovens will not allow you perform any cooking related actions until the clock is set to a valid time.

Assuming these are not your problems, a fuse has probably blown although a dead controller is a possibility.


While you can do some repairs on your microwave, what you don't know can kill you... even on an unplugged microwave, so make sure you understand the dangers and how to reduce them before you try anything inside a microwave. If you want to do more yourself, go to the link at the top of this post.

Blowing main breaker


I have a hard time believing that the home's main breaker is tripping instead of the branch circuit breaker that feeds the microwave. I suspect it is really just a difference in terms. You should disconnect it and try using in another outlet - preferably one on a different circuit if possible. If the breaker continues to trip; this appliance should be disconnected and either be discarded, repaired or replaced before using again.

If the microwave works as expected (on a different circuit), it may indicate the original circuit is overloaded. Microwave overs are supposed to be installed on a dedicated circuit. This means only one outlet is on the circuit - no other loads (lights, appliances, etc.) are permitted on this circuit. A microwave typically requires 10 Amps or more when on "high" and will require a significant portion of the power supplied by a 15 or 20 amp circuit breaker. There is little unused to power much of anything else. If other appliances go out when the microwave trips the circuit breaker, you should contact an electrician to have a dedicated outlet installed for the microwave.

I hope this helps!

Our GE JVM153SH microwave continues to blow the elecctric panel evety 4-6 months. why ?


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.

I went to use my mirowave & it is completely gone. I pushed every button that I could & nothing happens. What should I do


first check the breaker in the electrical panel. your microwave should be on a circuit with nothing else. Depending on when the house was constructed. If the breaker is tripped turn it off and back on. If the microwave is plugged into a gfic outlet check to see if the receptacle needs reset. There will be a reset button on the receptacle. Their may be a orange light on the receptacle.

Chek the high voltage capacitor and the diode . If one of them are short there is a chance for tripping the breaker

The past Few days the microwave would trip the breaker. today I went to use it and it worked for 30 seconds when I checked what I was heating and turned it bakc on and it would not work


Microwaves that are either built in, a part of the oven, or over the range are on a dedicated circuit by law. This means nothing else could have tripped that breaker but the microwave.
If it has a problem severe enough to trip a 20 amp breaker several times, it is only getting worse each time you reset the breaker and turn it on.
There is a possible chance of fire. I recommend you turn the circuit breaker off and replace the microwave. Is it a plug in, or over the range type?

I pluged the microwave in it was working and when I pushed it back and when I looked at it it waqs not working any moren mdl # is 87449 kenmore counter top microwave


Check the outlet it is plugged into. Remove the microwave plug. If you don't have a voltage meter handly to test the voltage at the outlet or the continuity of the microwave plug, I would suggest you plug in a lamp from your living room into the outlet. If it doesn't work, either the outlet is a tripped (GFIC) Ground Fault Interuption Circuit outlet or the circuit breaker tripped in your electrical panel box or the microwave cord is damaged and caused a short and blew the fuse. To check these I would try plugging the light in and press the red reset button located on the wall outlet or flip tripped circuit breaker in panel. If it's a damaged cord or fuse, you can visit this web site for Sears parts www.searspartsdirect.com If you found any of these suggestions helpful, please rate my solutions. Thanks D. Lange

Breaker tripping


Make sure it is plugged into a 20 amp circuit. If it is in a kitchen it should be a 20amp breaker if it trips a 20 amp breaker it needs to be replaced. If it is a new house and you plug it in in the kitchen and it trips a 15 amp breaker then the house does not meet code. ref Article 210.52(B)(1) NEC
