Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

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

I have a GE Spacemaker Over-The-Range Microwave Model #JVM1533WD002 that has worked perfectly for 10 years. Now everything still works, except it doesn't heat the food. Where is the fuse located and how...


A common symptom of a failed magnetron is a failure to heat with everything else (magnetron fan, stirrer, timer, etc.) working fine. Check the GE manufacture date for the unit on its nameplate to determine the age of the magnetron. For GE models of the past, magnetrons had a 10 year parts replacement warranty. Magnetrons can be expensive, so you need to weigh all your options, i.e., repair versus replacement, before you commit to one solution.

My Whirlpool microwave model MH6130XEB-1 made a pop noise and now will no longer heat food. Everything else works fine, clock, timer, fan, turn table, etc. Is this a fuse problem?


It can be the fuse supplying the magnetron, or the magnetron itself which has failed. Another suspect is the high voltage capacitor in this circuit.


Don't try to fix this yourself as the internals of a microwave are dangerous, with high voltages even when unplugged.

My microwavedoesn't heat is there a fuse that may be blown


No! the fuse is fine, there are three likely causes, magnetron, "heats food" cracked high voltave diode, or a shorted high voltage capacitor.

My Goldstar MV1608 stopped rotating and heating food yesterday. All other functions seem to be operating such as the light, fan, panel, etc. It is 18 months old. How can I fix it?


If there is no heating it is possible that the MAGNETRON has failed provided there is supply feed to the unit when the microwave is powered. Normally the magnetron along with the fan and light comes on when the microwave power is triggered. So since the rotation is absent it is possible that there is no power feed from the processor board which can be related to a driver failure. You need to check the output from the PROCESSOR to confirm and pinpoint the defective component. Check the relay to the magnetron trigger as this can be a suspect.

Lights, Fan works but it doesn't "nuke"


Your magnetron may be shot. Best to go shopping. Not many repairable parts on a microwave. Plainly, it's more expensive to have iy checked out.

Microwave won't heat, already tried replacing fuse. Timer, fan, clock work.


In all probability, the magnetron has died. The magnetron is the part that creates the microwaves that cook your food. Magnetrons are usually covered under a 5- or 10-year warranty and replacing them yourself can be pretty dangerous. I'd suggest you call a technician.

Doesn't heat


Sounds like the magnetron has failed possibly. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

If we close the mircowave door the units start to run by itself. - it will not heat, but the light comes on and the turntable rotates it will not stop until we turn the power off - when power is turned...


i think you have a welded controller, either a digital one or a mechanical one. microwave won't run unless you switch it to run. the door switches are safety switches to turn off the microwave once you open the door. if you have a digital controller, you could have a welded relay, if you have a mechanical timer, it could be a welded contact at the timer. another thing is that it should heat what ever you are heating. if it is not heating, check if it has a fuse and if it is busted. some fuse are installed to protect only the magnetron that is why the light and turn table are still running. if there is no fuse to the magnetron, then check the diode from the capacitor to the ground. it could be open. if not then you can have a bad magnetron. i hope i was able to help.
