Microwave Oven Basic Troubleshooting Tips

This is most likely a bad magnetron, but it could also be a bad high voltage diode.

I would check out this website
http://www.applianceaid.com/micro.html

Or you could call a local Appliance Repair Technician

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.

It's most likely a bad door switch or mount. See this file for help on diagnosing, ordering and replacing door switches.

the link below will take you to the installation instructions if needed.
It is much easier for two people to remove the microhood. If attempting alone, please move the range out so you can get under the micro to support the weight. If the range stays in place, protect the top from damage.
1. make a landing site to the side to protect the floor when putting the micro down after removal.
2. Disconnect the power cord in the cabinet above.
3. loosen the two screws in the bottom front corners of the cabinet above. When removed the front of the micro will drop, be ready for the weight. Busy times, tools in hands microwave coming down in front.
4. tilt the front down. pull the cord out of the upper cabinet.
5. with micro still tilted down in front, lift the back of the unit upward to free it from the wall plate.
6. remove the fasteners in the wall plate and remove.
Congrats, begin celebration.

If the oven is completely dead, (no light or display) it probally is a fuse problem. It does have a 20 Amp fuse. With that being said, I would stress that a qualified service technician check it out. There are some high voltage components inside and a person who is unfamilar with high voltage components can seriously get hurt or even die if they don't take the proper precautions working with this type of appliance.

My Kenmore microwave oven fan has been turning on and off, almost every hour. Sometimes 3 or 4 times in one hour. It's very random. Model No. 721-80593401 Serial No.503TA03208
Please help!!!

It may be a shorting pad (the hood / vent fan pad) on the keypad or a part on the control board.

Absolutely - If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and please do not leave it running unattended.

We regularly repair these control units for customers nationwide by mail for $39.95 postpaid in about a week or so with a one-year guarantee.

If you need a new keypad, that would add about $37 to that cost.

Feel free to visit our Web site or contact me directly with your model number and symptoms.

I had this problem before. Look on the display. Is there a little 'd' on there? I can't find my manual, but inside it shows you the combination of buttons to push on the display to fix this. Anybody else know the secret combination? What the heck does the "d" stand for anyway?

It sounds like you're saying a flame and pop came out of the area where the internal electronics are? If that's the case, then I would suspect a failed high-voltage transformer, bad magnetron or that another high-voltage component is arcing, like maybe damaged wiring, but that's rare unless... ... I hate to suggest it, but maybe a "critter" has made his way into the high-voltage section! That can cause some really "interesting" effects! If the flame and pop are coming out of the cooking cavity, then it could be food debris or grease underneath the waveguide cover or in the waveguide. I would say the likliest cause is a failed HV transformer. If it's still under warranty, I'd call Sears right away to verify that. If it's not under warranty, you may want to pull it from the wall yourself and take it in to Sears or another shop yourself. You'll probably save about $50 as opposed to letting them come out to the home to service it.

This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

It has a bad relay on the control board. The board will need to be replaced.
