SOURCE: My Frigidaire over the stove microwave not heating food

Hi,It is most likely the magnetron and diode that has to be replaced. This job should be done by a tech, High voltage. Magnetron's normally have a five year warranty, check your owners manual.

SOURCE: Frigidaire microwave does not heat but will not shut off either.

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

Thediode and capacitors can br tested. The capacitor must bealloweddischarge before testing, or you risk to get electrocuted, evenifpower is off. Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
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.

That's probably a shorted relay on the control circuit board.

We regularly repair such control units for customers nationwide by mail for $39.95 postpaid with a one-year guarantee.

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.

Perhaps the "repairman" should take another look at it. A lot of microwave ovens have an aerial that directs the energy out to the load or food to be heated.

Every time the microwave part of an oven do not heat it normaly means a faulty MAGNETRON (the device that produces microwves) unfortunately if it's the magnetron they are allmost as expensive as the oven it self, you could allways check for a burned fuse, (allways be prudent opening an applyance)

Good luck!

Small amount of white smoke coming out of kenmore convection microwave in oven mode


That is usually caused by a build up of fat from microwave cooking on the heating element. It will clear under normal conditions and return if one cooks foods like bacon etc, un covered to prevent splashing of the food that is being cooked.
Hope that helps.

I inherited a 1986 J.C. Penney Microwave and can't figure out how to program most of the features. I need an operating manual or a gnome.


The clock must be set before you can use the microwave. When you plug it in, it should read all zeros. Enter the time, and press "Clock Set." Time is in 12-hour format. There is no daylight saving time.

For basic microwave use:
1. Press "Power."
2. Press the keypad corresponding to the desired amount of power, e.g., "High," or "Defrost." (The numbers on the keypad have little words on them, like "Warm," "Med," and "High".)
3. Press "Time."
4. Enter the desired cooking time, e.g., "1-0-0" will be 1 minute; you could also do "6-0" for 60 seconds. You can do as little as 1 second, up to 99 hours 59 minutes. "1-0-0-0" would be 10 minutes. "2-0-1-2" would be 20 minutes 12 seconds.
5. Press "Start."

NEVER operate the microwave when it is empty. Put at least a glass of water in it. Never put a glass in it empty; make sure the glass has something in it, like water. Be careful when taking out a glass of water that's been heated; the water has been known, in rare instances, to "explode" and severely scald people.

It is okay to use the approved metal rack (it's coated with ceramic to prevent arcing) when using the microwave in microwave mode. Of course, the metal rack is also fine for use in the convection/combination mode.

"Defrost" cycles between microwave and nothing, microwave and nothing, microwave and nothing. You can hear the cycles. If defrost takes too long, try "Low." Try to avoid using "High," as it kills most nutrients in the food. Opt for "Medium" for slightly longer time; it'll be more evenly heated and healthier. Some things, like popcorn, require "high" power.

To stop the microwave in the middle of cooking, simply open the door. (There's no such thing as microwaves escaping the oven and bouncing around the kitchen and zapping you. I have a microwave tester, and the moment you open the door, all microwaves dissipate; the reading at the door is "Zero" once it's opened.) Or, press "Cancel." If you open the door, you may test the food, and if it needs further cooking, you may close the door and press "Start," and it will resume where it left off. If you're all done, just press "Cancel."

There is no way to disable the 5 beeps at the end of the cycle. If the baby is sleeping and you don't want to hear the beeps, simply open the door right before the beeps when the countdown is at zero. Pressing "Cancel" will give you one beep.

If you have the Combination feature, that cycles between microwave and convection heat, giving the best of both worlds (cooking inside with microwaves and outside with convection), for things such as a whole meats.

To use Combination:
1. Press "Combination."
2. Consult the chart on the microwave (below the keypad) and choose a number from 1 to 4, depending on what type of food you're preparing (i.e., lamb, pork, etc.).
3. Press "Time."
4. Enter the desired time, using the method described above.
5. Press "Start."

The Convection feature simply blows hot air across the food, at the temperature and duration that you set. It's a great way to toast slices of bread for the whole family at once, or bake a pizza.

To use the Convection feature:
1. Press "Convection."
2. Choose the temperature (the degrees are printed on the keypad, such as "350 degrees."
3. Press "Time."
4. Enter the length of cook time, using the method described above.
5. Press "Start."

Be sure to cover foods (with a paper towel or suitable plastic cover) that are prone to splattering. Don't let foods explode and get up into the motor. Clean the inside regularly with a soft sponge and mild detergent, NOT harsh or abrasive chemicals like Comet. Then rinse the soap off with a clean sponge.


Be sure to close the door firmly before cooking, but don't slam it. Slamming it will wear out the latching part, but being too gentle in closing the door may cause the safety switch to not engage, and the microwave won't work (it'll count down and the light will turn on but the motor won't run).


Note: the Convection feature uses more wattage than the microwave counterpart. The volts and amps are listed in the door jamb; multiply them together and you get total watts (although the actual amount will vary depending on your "power" settings).

Convection oven problem


Most of the time the magnetron is defective if the food is not heating up.
In some cases there is a defective low power transformer or other componenents associated with the magnetron.
I would suggest to check the owners manual under the warranty section. Sometimes the magnetron has 5 years warranty.
Good Luck.
