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 conneciton on the control unit circuit board
- bad magnetron or other high voltage part

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.

F2 on this model means you have a shorting
If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.
So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and please do not leave it running unattended.
On this model, the membrane keypad is available already mounted on a new control panel frame. It runs a little more, but saves a lot of time consuming and aggravating work.
In this case, you simply move your circuit board into the new frame.
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.
Then you remove a few more screws and disconnect the wires.
It is part # AP3673562 (same as 8205018) and runs $80.97 + shipping here.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
