Question about GE JVM1440 Microwave Oven

1 Answer

Microwave Circuit trips First: It began after some watery contents spilled out while microwaving from being turned on for a very long time (the most ever) overheating. It spilled over and some seeped out the closed door. I don't remember if it tripped itself off or went to its completion and then turned of automatically or not but I remembered I discovered the mess after it was off for a time and the door still was closed. It had apparently spilled through the closed door onto the table and onto the floor. The entire inside was flooded with watery pea soup. After cleaning up this mess and waiting a day and a half for it to dry out, I tried using it and the local red button on the wall circuit tripped. I then moved the microwave to a different three pronged wall socket which didn't have a red circuit breaker button - in a different part of the house, and it appears to be OK. I only tried this test for a few seconds though because I wanted to ask someone who may know if they think its wise to use it in this other place (not with an extension cord but directly into the socket) since my kitchen red circuit breaker still pops IMMEDIATELY the second I just begin to insert the plug into the socket - the microwave being turned off as I do this. Thanks for reading - any advice would be appreciated. Hope its not too confusing.

The outlet with the red button is a GFI (ground fault interrupter) type. It may have been damaged when the microwave overheated. If so, it may trip when loaded.

You should do a full two minute heat test with a cup of water with the oven plugged into the standard type outlet that you tried second.

If it works fine, then i would suspect that the GFI outlet has failed and needs to be replaced. "When in doubt, throw it out", as they say.

The microwave does not need a GFI type outlet.

But do be sure the microwave's internal cooling fan is running properly.

When I say internal cooling fan, I do not mean the hood vent exhaust fan which you can turn on and off manually.

I'm instead talking about the internal fan which comes on automatically whenever you microwave.

It is vital that the cooling fan runs, or the magnetron will soon be destroyed.

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are working.

If the turntable and/or inside light do not work when you cook, that's a bad sign, too.

If the microwave still fails in the standard outlet, it has a problem that needs to be addressed.

If you need further help, contact me directly or post a new detailed help request here and include your full model number from the tag on the oven.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Smeg microwave shorting


If it's the circuit breaker in your house or apartment that's blowing, then either you are overloading the circuit, or you have a bad breaker. Check to see what other devices might be plugged into that circuit, and move as many of them as possible to a different circuit.

Keeps tripping circuit breaker


There must be a fairly major issue with your microwave to trip a 20 amp breaker. I would recommend taking it to your local repair shop or replacing it.

Tripping GFI


proceed using the common sense. You must open the microwaves for to see what happen, the coffee produce bad contacts, and reaction from component like short, etc. However the following. God bless you
Door Switch If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently.

Main Control Board If the microwave runs for a few seconds and stops there may be a short circuit in the main control board. Check other components first, these boards are often misdiagnosed.
Touchpad and Control Panel If the microwave runs for a few seconds and stops the touchpad and control panel might be defective. There are several other components that can cause this problem, be sure to check any other components before replacing this board.

Touchpad If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the dishwasher display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.

High Voltage Transformer If the microwave runs for a few seconds and stops the high voltage transformer might have an intermittent short. This is not common. Check other components related to the microwave symptom first.

Thermoprotector If the microwave runs for a few seconds and stops the thermoprotector may have tripped. This is a safety device to prevent the microwave from overheating. It can be tested for continuity to see if it's blown.

Thermostat If the microwave runs for a few seconds and stops the thermostat might be defective. Watch our video on testing thermostats.

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!

The power cuts off after 2 minutes of cooking. The microwave doesnt turn back on for ten minutes.


There is an automatic circuit breaker that it tripping. One of two options
1) Something in your oven is either malfunctioning (difficult to find and replace). It is likely better to just replace than pay to have it fixed.

2) The house circuit that you are using is not providing enough power to the microwave. Check if something else is connected on the same circuit. A microwave runs poorly when not getting the full 115 volts that it was designed for and may fall into a safe mode and shut down for a while.

Newer houses should have the microwave on a dedicated circuit and should not have this problem - I say should not because electricians can make mistakes too.

You can try to trip your microwave circuit and see if anything else stops working. If so, that is likely why your microwave is falling into a safe mode - it is not getting enough juice.

If you have an older home (pre 1995), try to find what else is on your microwave circuit by tripping the breaker as listed above, then not using the other appliance when using the microwave.
Good luck.

Dead microwave


There are replacable fuses inside. Taking the microwave apart requires removal of a lot of screws and the cover that can be rather bulky. make sure it's unplugged and safe before you begin. you can get replacement fuses at radio shack, ect. be sure to buy the same type and amperage. if the blow a second time there may be other issues.

Blows the powerstrip


Hello. I can help you. Let me review some info. about microwaves.

First of all, a microwave requires a lot of power. Most microwaves must have their own circuit to work well for a long time. Do not use any powerstrip or other extension cord, always plug a microwave directly into the wall.

The problems you are having are most likely due to your powerstrip than to your home wiring.

Plug your microwave directly into the wall and use it. If it works then discard the powerstrip as it is a fire hazard. get back and let me know how u make out.

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?
