My 2.5 year old KitchenAid over-the-counter microwave will not heat. The light, fan, etc. all work. We ordered another one, installed it, and SAME PROBLEM! Help, could it be a wiring issue with the house?

    Do you mean the circuit in the wall, because the replacement microwave that we bought off ebay (brand new, in the box) had exactly the same problem! What are the chances of that?

  • tallen30 May 26, 2009

    We actually did run an extension cord, and try another outlet.



    It is so frustrating!!

Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

    Have you tried other outlets in the house before installing it? Try running an extension cord from a different outlet to it and see if it will work. I would also advise trying it in another house. GE microwaves are known to have this problem so I wouldn't doubt it having the same problem in both units although the chance is low.

    yes, well sorry to hear that, it still sounds like a second faulty unit though I would try at another house first before writing to the person you bought it from on ebay

I have a counter top kitchenaid microwave that does not power up or tune the light on until I hit the side of the oven. Is this repairrable otr should I just buy a new one. It is about 10 years old.


We would need the model number in order to provide you with free assistance.

It is usually found on a tag located inside the cooking cavity or around the door frame or controller frame.

Since FixYa is still not notifying us when you respond to clarification requests, you will have to post a new help request with your model number and symptoms / questions.

Buzzing sound... Turntable stopped. food heats up but uneven. No microwave fan when heating.. no light inside expensive fix?? Unit is 10 years old


If the microwave oven is 10 years old then it is time to consider a new unit, by your description it is going into cascade failure where different parts have stopped working, the buzzing sound is the magnetron warning you, it is about to fail. The fans job is to keep the magnetron cool while it is running.

No heat in microwave


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. (here in UK).
