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.

A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########

Makes a humming noise wont heat

If its making a humming noise, that means the diode is bad and should be replaced. Once replaced the microwave will begin to heat again.

My Kenmore 721.626222 which I have had about 6 years, runs but does not heat. There is also a strange smell - something like a burning smell.

When the oven does not heat, the problem is usually due to the magnetron failing. It the part that generates the microwaves that heat the food. It fails by shorting out causing a loud buzzing noise. The burning smell is the being magnetron overloaded due to the short. It not worth fixing since the replacement cost of a magnetron is close to the price of a new oven. Sorry.

MICROWAVE NOT HEATING

Most likely you have a magnetron problem. Easy to replace (DYI) but make sure the high voltage capacitor is fully discharged first against the case.

If you removed wires to test mag tube and it's not infinite from either terminal to ground, it's shorted. Mag tubes will buzz like that. Also check high-voltage diode. Should have infinite in 1 direction. If in doubt, replace also.

Ticking sound when running microwave

It may be a noise coming from the turntable motor or stirrer motor, if so equipped.

If it's not too loud, I wouldn't worry about it unless it gets louder or you get further symptoms.

The problem is likely on the control panel, which we repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This often can affect the exhaust fan operation, too. The lights and fan can be inopoerable or stuck on.

Microwave buzzing

It's likely a bad magnetron or maybe the high-voltage transformer. If it's within the warranty period of the magnetron (5 years or less), I would call Sears. In my professional opinion, no one should work on a microwave unless they are fully informed and aware of the deadly hazards and necessary precautions.

Microwave makes loud buzzing sound when on and no heat

Have you tried putting a cup of water in it and cooking on a low power level? If it buzzes only when it is on the cook cycle, that would narrow it down. More detals might help us help you, including the model number.
