Microwave is not cooking/heating.

IT'S THE MAGNITRON - CHEAPER TO BUY NEW THAN REPLACE - SORRY.

If everything seems to work, except cooking the food it is probably the magnetron which sells for $100-$150 for the part alone.

you may have gotten a power surge and that can cause some funny things to happen, 1st is there power to the oven, 2nd if so there may be an internal fuse protector built in to the oven, check with the manual for anything of that sort listed. if not you may have to take it in and have it repaired by a pro. there is a lot of voltage in these ovens and unless you know what you are doing a person could get hurt

PRELIMINARY REPLY

This is just a preliminary reply. We will need more information to help you.

So you're saying you can set the cooking time but when you press Start it won't start?

If this is the case, you probably have a bad door swithc or door switch mount.

Please reply back with more detail so we can help you.

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.
