We have a Kenmore 1000W over the range microwave. Puchased in 2006. All works great accept last week it no longer heats the food items inside. Could it be a fuse since all else is fine? Were would it be located? Thanks.

Re: Microwave not heating items
If it is fuse then there should be no lights or display at all. if there is, then it is not a fuse. it could be the magnetron.
the fuse is located inside the microwave. you have to bring it down and open the cover.

If it sounds like it is running and it lights up it is not the fuse. In my 24 years of service work I've found that the problem you are describing is cause by the failure of the magnitron ( The device that emits the microwave radiation). As your unit is a built in expensive unit I would look into replacing the magnitron. In cheap microwaves I just suggest replacement. If you need further assistance locating a replacement magnitron feel free to cotact me. It is a relatively easy part to replace. You just open the case and unplug it, unscrew it from the unit, and replace it with the new one. In most cases all you need is a philips head screwdriver and some patience. Anyway, I hope this helps you out in your decicion.
the unit inside the microwave that heats called the "magnetron" has gone bad or the circuits that power the magnetron and other parts of the unit have failed. if its under warranty still, send it back to the manufacturer. if not you can call some repair shops and see how much it would be to service it, but its most likely going to be cheaper to purchace a new microwave since they are relatively cheap these days, they dont make them long lasting anymore, they are a "disposable" product these days
So we can help you, please post a NEW question, and please
include your model number MA-1000Was well as the answers to these questions:
When you try to microwave are the inside light, internal cooling fan and turntable all working?
Is there any unusual noise or is it louder or quieter than normal?
A loud buzz, hum, or groan is usually a
shorted high voltage rectifier diode, but a sound like gurgling into an
empty coffee mug is one symptom of a failed magnetron, and yet the mag can
be bad without that sound. We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are working.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
When the microwave sounds okay, but there's no heat, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. As there was power loss due to storm so I believe it could either be the the high voltage circuitry, or the circuit board . To resolve this problem, you need the assistance of a qualified appliance repair technician.
