How to make repairs on Kenmore microwave overn 721.66223

Yes it is repairable, but if you do not have any experience in the repair of microwave ovens do not engage in their repairs because it is one of the most dangerous household appliances and the consequences can be disastrous. If light and turntable works than low voltage circuit (220V or 110V) works well. In this case the problem is in a high voltage (HV) circuit which is made up of the magnetron, HV diode (rectifier), HV capacitor and HV fuse or protect diode. Failure is in any of these components in "HV circuit" or in the main board. If light and turntable does not work than fault could be in power supply elements like: power supply cord, transformer, power board, fuse (glass or ceramic, ussualy 8A, 10A or 12A) on power board.

Hello,

Check the turntable guide to make sure it is lined up properly and that there is no debris caught in it. You may need to re-align or clean your turntable guide.

Cleaning and realigning a turntable guide;

Remove your glass turntable cooking tray from your microwave. Gently wash with warm soapy water to remove any debris. Next remove the turntable guide and clean it in the same manner, with warm soapy water. Pay particular attention to the turntable rollers. There could be spilled food particles caught in the rollers, hindering the rollers' movement. Also, gently cleanse the internal cavity of your microwave, paying special attention to the area below the turntable.


With the internal cavity, turntable, and turntable guide completely clean and dry, return the parts to your microwave. First place the turntable guide on the bottom of the microwave. There should be a circular groove in the bottom of the microwave cavity keeping the turntable guide in place. Follow the guide with the turntable cooking tray. Carefully place the glass tray over the turntable guide and onto the drive bushing. The drive bushing should fit neatly into the grooves on the bottom of your glass cooking tray. It may take some adjusting before the tray will sit properly onto the drive bushing.


Test your microwave after this thorough cleaning and realigning in order to determine whether this has solved your problem. DO NOT run your microwave with nothing in it.

CAUTION: Your microwave oven is capable of giving you a serious electrical shock, even when it is unplugged. We strongly suggest you seek the assistance of an appliance repair technician when conducting any microwave oven repair.

Also, Examine the plastic drive bushing the turntable tray sits on. It may have become worn, or even may have split in two;

Drive bushing replacement

Inspect the plastic drive bushing located below your microwave oven's turntable tray. There may be some debris blocking the tray's range of motion. Clean away any blockage you find, and then test your microwave to see if this has cleared up the problem. DO NOT run your microwave with nothing in it.


However, if upon your inspection, you notice that the plastic drive bushing below the turntable tray is worn and/or broken, you will need to have the bushing replaced. Consult with a certified and experienced appliance repair technician. Replacing a drive bushing is a lengthy and involved process that the average layman should not perform.


Good luck.

This problem is commonly caused by a turntable motor that has worn out and needs replaced. The following link explains how to access and replace one:

http://www.fixya.com/support/r3555716-replacing_a_turntable_motor_on_a_microwa

This is a very simple repair, that usually is not expensive. The motor usually averages about $35 - $40, but the price also depends upon the model. This repair can also be performed on an over the range model microwave oven WITHOUT uninstalling it.

You can purchase replacement parts at the any of the following websites:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

The first three sites listed offer helpful exploded view diagrams to assist you in parts location/identification. If you have any questions, please post back with your model number and let me know. I hope this helps you.

Not familiar with Kenmore, however, in most cases the turn table is turned by a small motor under neath the microwave, which is probably faulty.
I don't advise you to repair without trained safety knowledge on microwaves, this should not cost too much to repair by an approved engineer.

It's called either the turntable coupler or the turntable support, depending on your model number. You can visit the Sears parts Web site at http://www3.sears.com/ and enter your full model number and see exploded view diagrams, parts lists, and order the part. Or you can call Sears parts at 1-800-252-1698.
