I see. Okay, well then I would expect there's a problem with a high voltage part, such as the diode, magnetron or transformer.

Your model number should be entered as JVM192002 and you can find exploded views here.

You can usually find GE parts for much less here.

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.

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

Likely takes a torx wrench or some other special star tool to open it.

Could be a bad relay a bad mag tube or a bad timmer or a bad door switch. Needs to be trouble shooted. You have to get it open and check the fuses and test the voltage on the pri transformer first.

With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron.

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.

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.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

(if it's not shorted or burned, it's probably okay)

Accessing some components for testing 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.

The owner's manual will also tell you how long your magnetron warranty is - it's usually 5 to 9 years.

SOURCE: Convection Oven has stopped working

magnetron may be defective . replace d magnetron

SOURCE: My convection microwave will not heat up in

usually if convection fails means there is problem in magnetron you hear an unusual buzzing noise, the magnetron (the component that actually generates the microwaves) or other electronic module may be broken. This is not easily fixed; contact a service technician.
