Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and
disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

There should be a very helpful "mini-manual" hidden inside the unit behind the control panel.

Please write back with more details if you need further help.

Thanks for making your post very detailed and including the model number. That really helps! :)

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 easy & cheap do-it-yourself 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.

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

This is a sure sign that the magnatron needs replaced ( This is what heats the food!) replace and all will be good again!
PLEASE rate my response to your question
