If it goes dead or blows the breaker or GFI when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. Other times, it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

It may be a blown fuse or the thermal cutout (T.C.O.) or thermostat on the magnetron or on top of the oven cavity.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

Accessing some components (especially the oven cavity thermostat) for testing and possible replacement will require you to remove the oven from the wall and take off the outer cover.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download GE owner's manuals and installation instructions here.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

The first thing you need to check is the GFI--when it trips, it definitely should shut off power to the circuit. It may be wired incorrectly, or is faulty. There should be a 20 amp breaker and wiring to the oven.It is also much better is the oven is the only appliance on this circuit. Hope this helps!

Started tripping the GFI outlet. Outley appears to functioning correctly after re-set, but the microwave keeps tripping it when I plug it back in


HI Joe
Couple of things to consider here.
  1. There may be a GFI plug there at the microwave, but it can get tripped by current leakage on other parts of the circuit. If there are other things plugged into the circuit (every outlet that's on the same panel breaker), it's possible any of them could be causing the tripping. Unplug anything else on the circuit, then plug things back in one by one to see if there's something that may make it pop.
  2. The reset switch in a GFI plug is mechanical. If it's been tripped a few times, it may be worn or not fully reset. Electrical guides usually suggest testing / resetting GFI plugs monthly, both to make sure they work, and also to cycle the mechanical switch. If dust, toaster crumbs, or other stuff might have gotten into the mechanism, it might not be mechanically resetting properly. Try test/reset/test/reset a few times and see if any of the clicks start feeling more distinct.
  3. The trip can be legit. Hopefully not the microwave, but if there is a short in the line somewhere, you really want to track it down before it causes a fire. In some cases, even heavy dust on/in outlets can cause pseudo-shorts with some current trickling to ground. GFI switches will usually trigger with less than 5 mA of current drop, so it doesn't take much. Blow out the receptacle with canned air.
The switch or it's connections may be bad. Unplug the microwave and (no cutting corners here), turn off the breaker to the plug. Undo the faceplate and mounting screws and pull the plug away from the wall. Check that the wire connections to the plug are tight, and that the wire nuts connecting the plug to the wall lines are also firm and tight. Tighten if necessary. If you're still getting trouble after trying this all, Consider replacing the outlet and seeing if that helps.

Hoping this helps!

Microwave clock and panel was lit in am wasn't used but in evening when went to use it isn't lit and won't work at all


Hello Anonymous

At the risk of starting with the very basics, when you say that the clock and panel aren't lit and wont' work at all, the first place to look is the wall power. You may be missing power from the wall because:
  1. The microwave isn't plugged in. Someone may have yanked a plug to plug in a mixer, phone charger, thanksgiving animated ornament, or what have you. Trace the cord back and make sure it's plugged in.
  2. Make sure the outlet has power. Take some plug-in-able item and plug to the outlet and see if it can turn on. If not:
  1. A number of kitchen outlets may have GFI switches, especially if they are anywhere near sinks. The GFI may have been tripped. There should be a reset switch in the middle of the plug. See if it's tripped, and reset if necessary.
  2. The breaker may have been tripped. Most kitchen circuits are wired to 20Amp breakers. If this is elsewhere in the house, like in an entertainment room or such, it is likely a 15 Amp outlet. Microwaves can draw a fair amount of power. Someone using another kitchen appliance, hair dryer, or what have you, on the same circuit, may have tripped the breaker. Newer code may specify an AFI or GFI breaker for kitchen outlets. In that case, a fault with something else on the circuit may have tripped the breaker. If that is the case, and it trips again, talk to an electrician. You don't want a fault like that undiagnosed.

    3) You may also want to try plugging the microwave into another outlet, even if the normal outlet seems OK

    If there's wall power and a good plug-in, then you work back to the microwave itself. A number will have fuses. Also, there may be interlocks that kick in if, for instance, the carousel rotation is impeded - that can mean something on the carousel is hitting a wall, which can risk tipping something over and spilling, or risk mucking up the reduction gears for the carousel axle if it keeps pushing.

    At that point, looking for specifics on your microwave model will be needed. You may also try the Microsoft Support approach - i.e unplug it for 5 minutes, then plug it back in and see if it works.

    Hoping this helps, Good Luck!

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.

Cant plug in microwave. Everytime i do it trips GFI outlet. Same story for all outlets in kitchen. Plug in anything else and it works fine.


Hi
It sounds there is current leakage within the oven, causing your safety switch to trip.
It would be best to have a professional check your oven.

You might try pulling the plug on the unit and leaving it overnight. The electronics may have locked up due to irregular voltage during the failure. There may also be a GFI (ground fault interrupter) on that circuit that has tripped for the same reason. Check the kitchen outlets for a tripped GFI.

My daewoo microwave/toaster blew my breaker upon resetting it and plugging in the microwave it blew again then it tripped my GFI what could be the problem?


Probably a short inside the microwave circuitry.  I had a Daewoo and had nothing but trouble with it.  Main board went out in a year, then again in another year.  Finally went to Home Depot where I bought it and was told that they had nothing but trouble with them and quit selling them.  Now I have a GE Spacemaker.
