    The
    first thing I would suggest is a hard reset. Unplug the unit for a
    minute or so. Then plug it back in, set the clock and try again.




    If that doesn't work,
    leave it unplugged for maybe an hour. Then let us know if the hard
    reset does not fix it.

    Any unusual noises? Is it louder or quieter than usual?

SOURCE: Microwave making noise, not heating

Was the noise something like someone growling into a coffee cup?

As odd as that sounds, that's a common sound for a bad magnetron to make, a hollow gurgling or sizzling.

It may be the magnetron, but 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

SOURCE: KENMORE MICROWAVE (HOUSEHOLD) LOCKED

It sounds like you press STOP two or three times to lock it. Maybe that (or another key) will unlock it.

The lock / unlock procedure will be covered in your owner's manual.

Or you can try a hard reset - unplug it from the wall for one minute, then plug it back in and try again.

If you don't have your manual, you can get one here. (Enter your model number without any spaces)

Kenmore Elite Microwave oven 63792 doesn't heat - all lights, turntable, fan, etc. work just fine.


Most likely it would be a bad magnetron since the light, turntable, and vent fan are running.

I'd check to make sure you don't have a door switch that isn't functioning properly. Also, might be a control panel or control panel interface issue.

Microwave is less than a year old. It looks like everything is working, timer, light, air, turntable, etc., but it doesn't cook.

Not heating


If the oven is doing everything else properly (light comes on, fan runs, turntable goes around) but there's no heat, you may have a failed magnetron tube (the microwave source). There's also a relay that controls power to the tube that may not be working correctly, or the control circuit board is bad. It's also possible one of the door switches is not working (so the oven thinks the door isn't closed), although this usually keeps the turntable and fan from running.

Microwave oven service is not for do-it-yourselfers. There are potentially deadly voltages present even with power off, and a chance of microwave leakage if repairs aren't done properly. Let a professional give an estimate to repair it, or just replace it if it's under $100. (When I was servicing these things it wasn't unusual for a repair to cost over half the price of a new one. That's one of the reasons so few shops still work on small appliances.)

Turntable will not turn


If everything works, light and micro heating.. then I have 4 possibles for you to check... 1st make sure you don't have a button that allow you to turn the turntable on/off... 2nd take the glass table out and check the center plastic spinner(pull it out) and see if its broken. 3rd your turntable motor is bad, and 4th the relay for your turntable on control board is bad... helpfully that will do it for ya.. good luck.. mike

Underneath Light funtion stopped working on Kenmore 62642 model


We see this a lot. The problem is on the control panel, which we regularly repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.
