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)

We're happy to help and we appreciate your thoughtful rating of our answer.

Since it sounds louder than before, it is probably a bad high voltage diode or magnetron.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

Sears may send you a magnetron to install yourself since it's under warranty. For that or warranty service, contact Sears at http://www.sears.com.

You can save about $75 by taking it to the shop yourself, as opposed to an in-home service call.

SOURCE: display panel works but no heat, no fan, turn table doesn't turn

This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

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.

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.

If you only need a switch, you can order a universal type here for $5 postpaid.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases in about a week or so.

SOURCE: Sharp microwave oven model r-1440 runs, but doesn't heat food

Assuming your inside light and turntable come on when you try to microwave, with the symptoms you have, I would most strongly suspect a bad magnetron or a loose and possibly corroded connection on the magnetron's terminal.

The best place to order parts for this brand is Encompass (formerly Tritronics).

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.

My still fairly new kenmore 1000 watt microwave appears to be operating fine but doesnt heat. What might be the problem?


When you hit "Start" to microwave, do the inside light, cooling fan, and turntable all come on?

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

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

Post a new help request with the answers to these questions as well as the full model number from the tag on or in the unit.

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

Does not heat anymore, power is going to unit, the clock, and fan work, light still works but it will not heat and makes a low growling sound when we try to run it. Help!


What you are describing is a problem with the magnetron and it has become faulty, that is the main part that heats the food, the growling sound indicates it is loading down the power transformer that energizes the magnetron. The repair cost will not justify the expense "costly" replacement of the microwave oven "cheaper" in the long run.

Sounds like a bearing is tightening up when it get heated up with use. Then after a cool down period it works normally until using it heats it up again. Eric

Noise while not running


don;t worry;
all you need to do is lubricate the fan bearings with light machine oil and make sure the fan is not hitting anything

Sear's microwave falling apart


If this is and Over the Range micro, the exhaust fan needs to run ANYTIME the cooktop is on. They make things for quantity and not quality, so the plastic has little tolerance for heat. Running the fan, diminishes heat off the front of the unit. Also, the micro MUST be at leat 24" off the cooktop.

Heating


If the microwave is working but not heating 9 of 10 times is the magnetron that fails.
Check this site for more info on the subject, you can also find that part in one of their sponsors.
Good Luck.
