Question about GE Spacemaker JVM1640SJ Microwave Oven
If there is no power at all then check also the door switch and thermal cutoff.
If it is working but not heating, then test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.
The diodeand capacitors can be tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, evenif power is off.Capacitors can get discharged by shorting their two contacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.
All locations, and description of this parts can be located using the diagram here: Counter top.
Parts must be tested to find out what is wrong.
Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.
Regarding parts, contact the seller here to purchase parts.
You can also order from MicrowaveSvc , they also provide parts.

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.

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.
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.
If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.
Here are some links you or someone you know can use for test help, but read their safety warnings first:

SOURCE: Everything works except heat
Sounds like you've had a failure in the microwave portion of the unit.
Microwave not heating problems when the timer/controller board appears to function properly, are related to the following components -

About 95% of the time it is the magnatron. If the microwave is under 5 years old that part is often covered under warranty. I would check your manual. If not the p/n is 8206335 and it's about $80 and fairly easy to install. I just looked and the magnatron is covered.
Labor to replace it would be about $125

If the microwave oven appears to be working but it is not heating the food, it is very possible that the magnetron, or its power supply has failed.
