Microwave has works but doesn't heat


Sounds like the Magnetron has stopped working. The Magnetron is is a specially designed powerful magnet that generates the high frequency microwave energy used to heat food.

Microwave seems to work but doesn't heat up


HI, when the Magnetron becomes unstable, the microwave will not heat anything. simply replace the Magnetron. This device creates the heating action and it is damaged and not functional at this time.

Microwave sedems to be working but not heating


Chances are the problem is a loose connection on the magnetron, a bad high voltage diode, or a bad diode.

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

http://www.gallawa.com/microtech/diode.html (if it is NOT shorted, it's probably fine)
http://www.gallawa.com/microtech/mag_test.html
http://www.gallawa.com/microtech/xformer.html

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

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

This is usually a shorted high voltage rectifier diode or magnetron.

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 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.
