    You were absolutely right! GE replaced the magnetron at no charge -BUT - since we didn't have a service contract - they charged us $200 to install it! Only cost $375 newly installed. Was it worth it? Don't know?

    Thank you for your help.

Here's your parts breakdown.

More than likerly a bad magnetron. That's #73 on your parts diagram. One quick check before replacing - There is a bi-metal snap thermal switch bolted to that bad boy, (Normally Closed). Check for continuity there and if it's good take it off because you'll need it for the new magnetron. They don't come with one. If it's open that's your problem. If you do replace the magnetron don't throw the old one away without taking out the magnets. The thing just pries apart and there are two 1/2" thick 3" diametermags, they are just too cool to toss away.
What is the best way to discharge the capacitor? Holding a screw driver by the handle and not touching the shaft lay it across the contacts and it will discharge. You may need two screwdrivers with a clip lead between them to get at the capacitor contacts.
Call GE Answer Center 800 626 2000 and dig through the phone menus to get parts. That Magnetron may have a 10 year warranty! They'll send one out to ya no charge.

I want to replace an old microwave from 1988: GE Model# JVM130001. What microwave will fit in that space?

Laura, most any over the range microwave should fit that space. It may hang a little below your height but that should not be a problem.

GE JVM130K004 space saver microwave not working

The magnetron is overheating, and the magnetron thermostat is tripping, interrupting power until it cools back down.

This is to protect the magnetron from being destroyed from overheating.

It may be that the internal cooling is not occurring or the magnetron is failing. Cooling can be compromised by:

- failed or failing internal cooling fan
- blocked air inlet or filter
- outer cover not installed correctly

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.


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 links to helpful exploded view diagrams and part ordering help here.

GE over the range space saver microwave

The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

Let us know if the hard reset doesn't fix it.
