Question about GE JVM1440 Microwave Oven

Tripping of circuit breaker

Once in awhile, when the door is opened rapidly, the circuit breaker trips for the microwave. It appears to happen only when the door is suddenly opened and never when opened slowly. I have taken it apart and cleaned it and checked the door switches. I am not sure how and why the door switches would be able to trip on the circuit breaker yet the fuse in the microwave never blows? I would like to repair this as I believe this could potentially cause more other serious problems.

Any help would be appreciated.

Thank you

    The microwave is on its own circuit breaker of 15A. I have moved it to another circuit breaker just in case the problem was with the circuit breaker and it is not. The new circuit breaker also trips once in awhile

    My Sharp R1480 often trips the circuit breaker while cooking. There are no other appliances on the 20 amp circuit. The system had been working for ~5 years. I replaced the 30+ year old breaker and the problem continues. The vAC reads ~ 120VAC and does drop instantaneously to less than 100VAC for very brief, unrecordable duration. Could an intermittent tube or capacitor cause this?

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.

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.

Trip Circuit Breaker

The circuit breakers may both be functioning properly. What might be happening is that both circuits have other current drawing appliances on them. The circuit breakers react to the sum of all of the currents drawn by all of the devices on that circuit. So, if you have a 15 amp microwave and an 8 amp refrigerator on the same circuit, you would overload a 20 amp circuit by 3 amps.

Generally microwaves should be on their own breaker. Hard wired ones are required to be by code.

If yours has a plug - make sure the plug is original with the unit, not added later or spliced onto hard-wired power leads.

Plug into and outlet rated 15A as the only thing on a 15A branch circuit and try again. If it still trips, try a 20A line and circuit. If it trips that, trash the microwave and buy a new one. Nothing is meant to be repaired inside.

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.

We have a GE Profile microwave and every time we open the door it trips the breaker. We turn the breaker back on and use the microwave and as soon as the food is done cooking and we open the door - bam,...

For a breaker to trip, you have to have an over voltage condition that is usually referred to as a short. Since your unit works in the cook cycle and only trips the circuit breaker when you open the door the short has to be in the door latch switch or reset circuit. So it wouldn't be that hard to repair, but since it is 7 years old and not the most energy efficient unit, if you aren't able do the repair yourself, then I would replace it!

You can get an idea of how hard the repair would be by going to the web site and putting in the model # off the ID TAG. Then look for the door latch assembly and that will give you an idea of the cost of the parts and get an idea of how hard it is to replace.

It just has no power. Nothing happened, I just went to use it and it was dead.

The main fuse is blown, "ceramic type" usually caused by a defective door switch.

Opening the door blows the fuse

more than likely you door safety switch has a short and every time you pull the door open the connections arc and trip the breaker or blows the fuse.

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

GE Spacesaver microwave trips the circuit breaker

Since power = voltage X current, 1.58kW / 120VAC = 13.166A

So this unit should be fine on a 15A breaker unless the breaker is bad, the wiring or a connection is loose somewhere between the breaker and the microwave, or the microwave's magnetron or high voltage transformer are failing and drawing extra current.

Microwaves should really be on the own separate breaker if at all possible. Plus, the more a breaker trips, the more work out it gets.

Have you measured the voltage at the outlet? If that's off, current and power will be affected. It should be about 110-125VAC.

A good power test for outlet and wiring integrity is a toaster, toaster oven, or hair dryer rated at about 1500 watts.

If it doesn't run and heat steadily, then there may be a problem with the house wiring or breaker.

If it passes this test, the problem is likely in the microwave.

We're happy to help and we appreciate your thoughtful rating of our answer.
