The extreme heat has opened up one of the thermostats / thermal cutouts (TCOs) in the oven.

If it was the bottom TCO or magnetron TCO, you should be able to access them by just removing the control panel.

But if it's the one on top of the cavity, the oven will have to come out of the wall, then you need to pull of 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.

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.

You should locate and look this over first.

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.

SOURCE: Burning Smell in microwave/convection oven

Assuming your inside light and turntable come on when you try to microwave, 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.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

GE Customer Service is here.

Otherwise, 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.

SOURCE: 900E Microwave Oven Door Won't Open even after

Your latch has come apart inside the door or inside the oven. Probably a spring separated or broke.

Remove the cover --WATCH OUT FOR THE SILVER CAN - LETHAL -- and try to release the lock that way. I think you will be able to open it from inside but I also think your trouble is inside the door, though I dont have experience on this model. If the trouble is in the door, you will have to disassemble it. Look for hidden screws or a plastic strip which must be removed to separate the door halves.

Good luck in your project.

MCD1611W New, popping popcorn in glass MW corn popper. 3-4 minutes to pop. After popped I open the door and after a few seconds the MW shuts down completely, no lights, no response to pad pushing.


Popcorn is a low-moisture food which can cause a microwave to overheat, as can a failure of the cooling fan or blocked vents.

You should always turn a paper plate upside-down on the turntable (slightly off-center for better heating) and place the popcorn container on top of that.

The paper plate elevates the popcorn for better exposure to the energy and protects the turntable from excessive heat.

Placing food off-center instead of in the center increases exposure to the energy and prevents the same spot on the turntable from being overheated repeatedly, which leads to material fatigue and cracking.

It's also a good idea to put about 1/2 cup of water in a 1-cup microwave-safe container in the corner of the oven when cooking low-moisture foods like popcorn, bacon, and potatoes.

The microwave's magnetron has a thermal protector (thermostat, TCO, or thermal fuse) attached to it.

If the magnetron gets too hot, it can be damaged or destroyed, so the thermal protector opens and disconnects the power to the whole oven.

If it is a resettable device, the power will be restored when the device cools. If it is not resettable, the device must be replaced.

FixYa does not directly notify us experts of responses, so if you have other questions, please contact me directly.

R-1481 start button won't work


I have a r-1482 model so I don't know how close they will be. The biggest issue I found so far with my particular model, yours my be the same, is the door safety micro switches fail primarily from opening the door while the unit is in the process of cooking which causes them to arc and burn the contacts resulting in premature failure. With an ohm meter, check the resistance of the contacts of each switch individually with the COM terminal lug temporarily removed and ensure the closed resistance is 0 ohms and infinity when the contacts are open. Measure from the COM terminal to the terminal in use either N.O. or N.C., with the switch button NOT depressed the N.O. will be open while the N.C. will be closed and with the button depressed they will be opposite, in other words N.O. will be closed and N.C. will be open. Another thing to check is that the door hooks aren't broken (they activate the safety switches. Should you remove the switch bracket to replace the micro switches, make sure you wire the switches exactly the way they were COM to COM, NC to NC & NO to NO, mount them in the bracket the exact way they were and adjust the bracket so that the switch buttons are just to the point of being fully depressed and no more when the door is fully closed. The micro switches may be different in model numbers but you can sub with a micro switch that has all three COM, NC, NO terminals and only use the terminals in use for the given switch. I used Omron p/n: D3V-16G-1C25-K from Mouser Electronics (800) 346-6873. Since you didn't indicate the control panel was not operational I won't go into that area. I can't say if the timer will count down or not if the micro switches are bad, but it's a possibility, further pointing to the switches. If the control panel or MW tube is bad it's my recommendation to buy a new oven, though you can get new MW tubes, diode & capacitor, it's not worth the shocking experience to the human body, not to mention the MW radiation.
Good luck if you still have the oven and decide to take it one step further.

Replace the buttons on a kitchenaid microwave Khhs179lss-5


First, you need to uninstall the microwave (MW) from the cabinet by removing the screws that hold it in place at the top. Open the cabinet doors above the MW to locate the screws.
You will need someone to help you at this point in removing the screws and dropping the MW down. Be sure and unplug the MW before you remove the screws.
Next, you need to take the cover/shell off by locating and removing screws A/R. They are mostly across the back and side bottom.
From there on out, you should be able to methodically find and locate the various fasteners that will get to the button pad.

Fan & Turntable start when door is opened.


sounds like there is a switch that is bad. you can go buy a new MW for about 200$ and in yours if there is a major problem then i would just go buy a new one but might be worth a repair man to come check it out


pleas do not poke around in the microwave as it carries a charge of 5000volts and can kill you even if not plugged in DON'T TOUCH THE WIRES WITH BRAIDS ON THE OUT SIDE if you must get inside of the unit

When starting to reheat a loud crack, explosion, sound occurred,


As long as the door latches correctly there should be no danger. Some items will cause loud "explosions" in a microwave, such as whole potatoes when the skin has not been pierced. If the food contains pickling spices for example, the seeds will explode with a very loud sound like a gun.

As long as the oven continues to heat, there may be no other problem. But I suggest you stay near the unit when using it. Watch for smoke and be alert for strange odors. You don't mention the age of your oven but if it is new you can call GE customer care at 800 432 2737.
