Test the high voltage capacitor, the rectifier diode.or the magnetron.

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.

If you try to heat something for a minute , the microwave will turn on for about 15 seconds then shut off . It doesn't even seem to warm the food.


It may need a reset. You can do that by unplugging the power for a minute or two, then plugging it back in and setting the clock.

If it still fails, you may have a failing cooling fan or a problem on the control circuit board.

Stops working after 20 seconds


The magnetron is over heating causing the thermal fuse to open to cut power, the only option is replace the part, but keep in mind it is the most expensive item to install.

Our Kenmore microwave oven recently stopped heating. The lights, turning plate and controls all work but with no cooking is occurring. The last time I attempted to heat something up I heard a cracking...


The most likely cause is a bad magnetron, "heats food" the other two possibilities are the high voltage capacitor and diode. The cost to repair will a approach a new microwave oven.

Microwave oven does not heat anything. Clock, turntable, lights work. I turned the turntable off while the oven was cooking--heard a noise, now it doesn't heat anything.

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 conneciton on the control unit circuit board
- bad magnetron or other high voltage part
