SOURCE: The power went out and resetting per book, only heat doesn't work

We have a sound clip of what a microwave should sound like when the cooling fan and all are working here.

With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.

The diode is a fairly cheap fix, and the mag will cost more.

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

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 usually find helpful exploded view diagrams and order parts by entering your full model number here.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

SOURCE: boiled water and it exploded, now the microwave is broken

Yes there is a fuse most likely a ceramic not a glass type. How long did you heat the water for? I have seen magnetron tubes which produce the microwaves to heat the item go bad and cause the case of the microwave to get very hot. This is unsafe and could start a fire, you can look inside the microwave and remove the mica or plastic cover which covers the wave guide and look for burnt paint. If you see any sighs of burning junk the microwave oven, or have the unit repaired.

SOURCE: microwave will not get hot. fan works, keypad

In all likelihood the Magnetron, or high power diode, has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

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!

We have a kenmore microwave oven & keeps tripping our breaker switch. Its not even a year old. What is the problem?


Your microwave should be on a 20 amp dedicated circuit. Often people add these later after initial construction and do not have an isolated circuit for it. If you have this on a circuit with other outlets or possibly the refrigerator, this can cause the circuit overload and trip your breaker. Try running an extension cord from another circuit that is not being used such as outlets, but not GFI outlets! and see if your microwave operates then. If not you have an internal issue with the microwave and it could be a defective Magnetron or doorswitch assy causing the problem.

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.

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.

No power to clock or microwave. Have checked breakers.


The main fuse in the microwave oven has probably blown, caused by a defective door.

Ge spacemaker microwave, new, keeps tripping the GFI but keeps running


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!

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.
