Our Kitchenaid microwave gradually has stopped heating. We heard a spark when warming up a cup of water and then it quit heating up. What could be wrong?

first, get your money back or get a replacement for no charge. now, unplug the oven for 15 minutes and try again. if no-go, then some device is faulty that only a tech can find

I'm guessing the model number would be KEMS308GSS0.

In some cases, this is a glitch that can be cured by unplugging it for 1 minutes, then resetting the clock.

In other case, it may be a bad keypad (membrane switch) or control board.

Please feel free to contact me directly if you need more help.

open by unscrewing screws on back and along left side bottom. this lets you swing up the cabinet showing the electrics. the red power line going to the timer is held in place by a metal wire holder that is riveted to the base. wire has a white sleeve between its insulation and the metal wire holder. slide wire and sleeve out to the side of the holder. slide sleeve to side along wire, revealing fuse. need a solder iron and an electronic parts store to get replacement fuse and solder it in. reassemble.


the fuse is a resistor that blows when unit is getting hot. use lower resistance fuse or just hardwire the power line straight through, no fuse, but watch for overheating (not likely) and maybe use breaker outlet

SOURCE: My GE Profile Microwave/Convection Oven stopped working.

Chances are that the thermostat / thermal cutout / T.C.O. (whichever it uses) has opened.

This can happen when the magnetron overheats, either due to it's failing, or if the internal cooling fan is not working.

It may also that be the 15- or 20A ceramic line fuse or the oven cavity thermostat / thermal cutout / T.C.O. (whichever it uses) has opened.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

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.

You should be able to get the fuse from a home center or local appliance parts store.

Accessing some components for testing and possible replacement will require you to remove the oven from the wall.

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.

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

When unplugging it for half a minute or so (this should reset all settings) won't help, it must be defect. When you are convinced you did press the right buttons and you are in the correct program you don't need to unplug. But for that you have to be sure it is not switched to oven. In 30 seconds it won't be warm enough to heat your coffee

Microwave made a pop noise and just stopped working? itys not respoding at all?


If there is spark please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is leaking and sparking to the ground. As you have mentioned it was stored, it is quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Now switch the microwave power on and use a cup of water to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. Replace with same type. If not check the waveguides within the cabin for food particles that can burn and spark, check for rust that can corrode and spark when the ceramic paint has worn out.
If there is heating without any issues, you can use the microwave safely

Sparks inside cavity


This is caused by exposed bare metal, food partical buildup or the magnetron itself, clean interior with warm soapy water until spotless and inspect inside cavity, if okay! test run with a cup of water.

Microwave JVM1441: looks heating okay but making like rattling scary sound


This can be sparking or ratiling from the truntable mechanism or motor. If there is spark please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is leaking and sparking to the ground. As you have mentioned it was stored, it is quite possible that insect can get into the oven and create soft spots.

So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Now keeping clear switch on , use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.

Finally check the turntable , a drop of oil can stop the noise , remove the bottom plate to access. If there is heating without any issues , you can use the microwave safely

I have a Baumatic microwave BTM17.3SS. It came along with our new kitchen approx 4 years ago. We usually only used it for warming things. Recently it has stopped heating!! It still rotates and lights up....


If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.

Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if contact is not through the microwave will not work.

Now keeping clear of the microwave, switch on, use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.

My radiators are getting warm when my heatings not on. Any ideas??


You can check your microwave for possible LEAKS and make sure there are no FOOD particles blocking the oven's fan system To check for leaks, place a DAMP paper towel around the door seals and place a glass cup of water in the microwave. If there are leaks of microwave energy you will find DRY or WARM areas on the paper towel. BE CAREFUL not to peer or watch the test, done on level HIGH for 1 minute. Microwaves may cook the vitreous humor (liquid in eyeball,) just like it would an egg. If the towel is dry or hot ANYWHERE after the test, TOSS the microwave. Your safety is not calculated by the cost of a new oven.Let me know how this goes; I have tested many older ovens and have found quite a few leaky ones.
