The most common problems of microwave oven are the HV capacitor, HV diode and lastly the magnetron which is the main part of M O. check the capacitor and diode first, if its okay, then you have a decision to make. replace the magnetron or the whole unit. magnetron are costly

Kenmore elite microwave model 721.79203010 problems


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.

My Kenmore Built-in microwave doesn't heat and the turn table doesn't turn. Model 911-47812200


It is good that the microwave does not work all together. It might be an interlock button or even a relay connection burn on the main mother circuit board.

Need a qualified technician. The service manual will be like $20-50.

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.

Kenmore microwave does not heat anymore.


Assuming your inside light, turntable, and internal cooling fan all come on when you try to microwave, with the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron.

The diode is a fairly cheap fix, and the mag will cost more.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

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.

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

http://www.gallawa.com/microtech/diode.html
(if it's not shorted or burned, it's probably okay)


http://www.gallawa.com/microtech/mag_test.html

http://www.gallawa.com/microtech/xformer.html

http://www.gallawa.com/microtech/cap_test.html

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven Sears parts site.

But Sears parts can usually be obtained for far less here by entering either the part number.

Kenmore microwave model 665.68681891 runs but won't heat


Test the high voltage capacitor, the rectifier diode.or the magnetron. If all this are fine, test the control board.

If it additionally does not spin and no light, then check also the door switch and fuse.

The diode and capacitors can br tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, even if power is off. Capacitors can get discharged by shorting their two contacts.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts. (here in UK).

My Kenmore 64663 still heats but I don'y hear the fan anymore while heating


If it's the internal cooling fan, you really need to get that repaired before you cook anymore with it. Otherwise, your magnetron will be destroyed.

If it's the hood / exhaust fan, then the problem may be the motor or a problem on the control board.If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

You can probably find exploded views and order parts by entering your model number here at the Sears parts site.

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

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.

If you don't feel confident to tackle it yourself, I would contact Sears for service.

Microwave cycles off


Does this happen just at the full power microwave cook setting?

Have you tried defrosting and doe sit do it on this setting? Does it run any longer in defrost mode?
