Kenmore micriwave won't heat!

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

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.

Your biggest suspects will be a bad connection or relay on the control panel, a bad connection on the magnetron terminals, a bad magnetron, a shorted high voltage rectifier diode or a bad high voltage transformer.

You can find exploded views and part numbers by entering your model number at the Sears parts site.

A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########

You may be able to find better part prices than Sears here.

Your magnetron may have a 5-9 year warranty, so check your manual for that. Sears may send you a magnetron if it's bad and warranty.
