Question about Microwave Ovens
4 year old GE Spacemaker 2 Microwave (JVM 2070). Mircowave comes on, makes sound like it is heating, but does not heat food. Panel, lights, vent work fine.
Tried unplugging, still same problem.
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.
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.
Here are some links you or someone you know can use for test help, but read their safety warnings first:
(if it's not shorted or burned, it's probably okay)
You can usually find helpful exploded view diagrams and order parts by entering your full model number 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.
Some manufacturers will send you the magnetron to do it yourself. If nothing else, you can save about $75 by taking it to the shop yourself.
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 and find your nearest authorized servicer here.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
