You could have a number of problems in this unit BUT let me WARN you of the extremly high voltage inside this unit first!.. Theres a capacitor and a diode connected together that holds a charge that could be open , Theres a magnatron or the magnatron thermal cutouts that could have went bad. Theres a relay on the control board that could have went bad so therefor the control board could be bad. The power transformer for the Hi voltage could have went bad but not likely unless you seen or smelled alot of smoke or oder before it went bad. Unfortantly, these days a good microwave, to have fixed, is about or almost 3/4 the price of a new one. Without troubleshooting the unit with a multi-meter your really shooting in the dark with what part is bad as it could also be a combination of parts bad that I described. If you think its worth it, take the thing in for an estimate, but I would highly advise against you doing it unless your famillar with the dangers and the high voltage points. Good Luck

Loud noise when cooking


I had an arcing sound coming from above the cardboard panel inside the microwave. When I saw it sparking I took the cover off and saw that these two aluminum looking things had come loose. I removed the cover and did a fair bit of 'fine tuning' to get it working again.

My still fairly new kenmore 1000 watt microwave appears to be operating fine but doesnt heat. What might be the problem?


When you hit "Start" to microwave, do the inside light, cooling fan, and turntable all come on?

Any unusual noises? Is it louder or quieter than usual?

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

Post a new help request with the answers to these questions as well as the full model number from the tag on or in the unit.

My microwave makes a loud humming noise when it is turned on.


May as well use the microwave as is until it terminates naturally. All microwave ovens buzz, that nothing unusual, but although you can replace a Magnetron, the cost is unusually high. By the time you take the oven down, open the case and fuss around, perhaps not making things any better; the fact is; a new replacement with a warranty is just over $100. Why bother?

Microwave is not heating


We would need your full model number and a little more information to help you.

Please note that FixYa is not currently notifying us Experts when Clarification Requests are answered.

So to allow us to help you effectively (at no charge), please post a
NEW problem to FixYa, and please include your brand name and the full model number from the tag in or on the unit, your symptoms, as well as the answers to these questions:

When you hit "Start" to microwave, do the inside light, cooling fan, and turntable all come on?

Any unusual noises? Is it louder or quieter than usual?

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

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.

If there's no unusual noise, it may just be a bad connection at the magnetron.

Sharp microwave stopped working


Is it totally dead? No display? Or just does not cook? If it made an unusual noise before it 'died' something probably shorted out.... You need an ohm meter to troubleshoot. If the fuse is open, switches and HV circuit need to be checked before replacing fuse. Sometimes on the convection Microwaves (not just Sharp) the fuse will 'rust' and open rather than blow. Or the fuse holder can over heat and fail.

My GE spacemaker microwave won't heat and makes an unusual sound


I have the same problem on my oven- model JVM1640WB and called an appliance repairman who is honest and reliable (I've used him before). He said the problem is with the electrode, to fix it is roughly $300. He recommended buying a new microwave rather than fixing it.
