If the fan works then more than likely it is the magnetron. Rarely the transformer

PROBLEM MAY BE A RELAY ON THE CONTROL BOARD OR MAY BE A LOOSE WIRE FROM THE HV TRANSFORMER CKT.

SOURCE: GE Spacemaker Microwave JVM165OWB005--No more heat!

If you look at consumer affairs.com, there are many problems like this with GE microwaves. Not a good track record, experiencing problems with mine as well.

SOURCE: GE Microwave JE2160 does not heat

Does it make any noises that it didn't before it failed?? It could be a bad secondary interlock switch, cook relay on the PCB, HV circuit problem or bad magnetron. You need an ohm meter to troubleshoot. If you take the cover off, you MUST short across the High Voltage Capacitor terminals to discharge any possible residual charge to prevent shock hazard.

SOURCE: I have the same microwave but it doesn't heat anymore

either your h.v. diode,h.v.capacitor, or the magnetron are faulty,the first 2 are reasonably priced, the mag can cost anywhere from $40 to $125

SOURCE: Microwave - no heats - vibrating sound

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.

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.

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

http://www.gallawa.com/microtech/diode.html
(if it's not shorted or burned, it's probably okay)


http://www.gallawa.com/microtech/mag_test.html
(it may pass the checks and still be bad)

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

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.

If it's under magnetron warranty, GE will send you the magnetron to do it yourself. Call them at 888-239-6832.

Be persistent. You may have to speak with a supervisor.


If you prefer to arrange service by an authorized service center, GE Customer Service is here.

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

I have a combination oven/microwave but the microwave is not working? what should I do?


It is most likely one of three things, magnetron "heats food" cracked high voltage diode, or a shorted high voltage capacitor. I recommend a professional to assess, chances are cheaper to replace microwave oven.

My Maytag microwave stopped heating. Everything


Generally the magnetron (the part that heats the food) is the cause if everything else still works. Unfortunately replacing the magnetron is barely cheaper than buying a new microwave though you can check out repairclinic.com to decide whether you want to attempt replacing the part.

Let me know how this works out for you.

Kenmore Microwave Hood Combination: over the stove Model #721.80602500


Disclaimer: I'm a DIYer, not a technician.

Our GE over-the-range microwave stopped producing heat yesterday while warming part of the T-giving feast. Everything else (fan, control panel, light) works fine.

After disassembly and testing last night, I discovered a defective "secondary door switch." Your Kenmore uses a similar switch (~$19 on-line), and that might be the problem. But it also could be other things, such as a bad thermal cut-out.

If you know anyone who's handy with a multimeter, most of the basic diagnostics seem to be pretty straightforward.
