Disclaimer: I'm a DIYer, not a technician.

Our GE over-the-range microwave stopped producing heat yesterday while warming part of the T-giving feast. Everything else (fan, control panel, light) works fine.

After disassembly and testing last night, I discovered a defective "secondary door switch." Your Kenmore uses a similar switch (~$19 on-line), and that might be the problem. But it also could be other things, such as a bad thermal cut-out.

If you know anyone who's handy with a multimeter, most of the basic diagnostics seem to be pretty straightforward.

The microwave screen should be reset if possible. I would disconnect. open up. and run a metal screwdriver across the circuit board in order to draw any latent static from the resistors or circuits. It is worth a try.

F9 code can mean something different depending upon the particular model.....
1.) IF your Microwave uses "UltraWave technology"/"SmartWave technology"...Then either the Magnetron has failed or the Inverter board has failed OR maybe the control board has failed (HUH?).
2.) IF your Microwave does NOT use "UltraWave technology"/"SmartWave technology" then one or more of the door switches has failed.

** "UltraWave technology"/"SmartWave technology" **
I'll explain a few things about this wonderful technology...
The control board (accepts the pushbutton commands) has to talk to the inverter board to tell it how much power should be applied to the magnetron. The inverter board will then power the magnetron and inform the control board if the magnetron is working OK.
If there is something wrong with the magnetron or inverter board or a there is a communication breakdown between the control board and the inverter board...WA-LA-----F9----

A pretty reliable test for the Magnetron is to operate the oven and listen for a ticking sound 5-6 times about a second apart. If you can hear the ticking....The magnetron has failed..if no ticking, the control or inverter board failed.

Note: This 'technology' may come in other flavors as well
