Rotu is right - it certainly could be crud on the waveguide vcover or waveguide. If not, it might very well be be a bad magnetron. My understanding is that GE had a run of bad magnetrons and/or other problems in the high voltage section, but I don't know if they publicly acknowledged it. If it's not a dirty waveguide problem, I would contact GE or an authorized servicer. If you don't have a manual, you can download it here: http://www.geappliances.com/service_and_support/literature/

Q - The microwave display counts down and the inside light is on,  but nothing is heating and the fan is not running.
A - This most commonly is a bad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common.
 Q - My microwave is running and sounds like it is working but will not heat up anything.
A - Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay.....
Q - The microwave makes a loud "hum or buzz" noise but will not heat up the food?
A - 9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section.

There should 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.

Some questions to help you or someone you know troubleshoot it:

When you hit "Start" to microwave, do the inside light, cooling fan, and turntable all come on?

If not, then you probably have a bad door switch or door switch mount and should see these files:

http://www.microwavedisplay.com/safety.txt
http://www.microwavedisplay.com/disassembly.txt
http://www.microwavedisplay.com/doorsw.txt

If the inside light, cooling fan, and turntable are all coming on, then the problem is in the high voltage section, and then the next questions arise:

Any unusual noises? Is it louder or quieter than usual?

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but a sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound.

If there's no unusual noise, it may just be a bad connection at the magnetron.

Here are some links you or someone you know can use (in order given) for high voltage section test help, but read the safety warnings first:


http://www.gallawa.com/microtech/diode.html
(if it is NOT shorted or burned looking, it's probably fine)


http://www.gallawa.com/microtech/mag_test.html
(continuity can be good even though mag is bad!)


http://www.gallawa.com/microtech/xformer.html

You can find links to helpful exploded view diagrams and part ordering help here.
I'd recommend that your bookmark this link to your favorites.



Accessing some parts may require you to pull the oven from the wall and remove the 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 owner's manuals and installation instructions for several brands (including Amana, Jenn-Air, Kitchenaid, Litton, Maytag, Roper, Tappan, Thermador and Whirlpool) here.

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

Micro wave runs but does not heat food??


The most likely cause is a defective magnetron "heats food" if the microwave oven is more than five years old consideration should be given to replace because of the cost involved.

My microwave starts however food does not heat up.


Micro wave as the name suggests produces heat when the micro waves aimed at an object causes the water molecules inside the object to vibrate hence producing heat.The gadget responsible is the magnetron. If your magnetron is not receiving ht voltage or receiving but faulty, then your micro wave wont work please take precaution when opening micro wave due to high voltage caps that remain charged sometimes even when it is off.check the high voltage fuse/ diode and capacitor if they are fine and the step up trans former o.k then the only option is to replace the magnetron
