Kenmore 721.63662300, 1200W

It started making a high pitched buzz or arc sound when first cooking for about 2 -3 seconds into the cook time. Now it doesn't make that new noise, it warms food some, but does not heat well.

The magnatron is shorting and overloading the high voltage transformer which is complaining with a load noise. Worth fixing if you do it your self. Magnatrons cast about $40 wholesale. There are just a few varieties of them that fit almos all brands. Try

Replace the magnetron and the wave guide.

Unit makes a loud buzzing sound whenever the unit has power.

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week.

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.

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

Details of our service and critical safety information and disassembly information is at our site, and our link is at our listing here on FixYa.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

Kenmore 721.80524500 makes a buzzing, grinding noise

Your problem is due to the "magnetron" arcing to the wave guide within the microwave. Picture someone arc-welding stuff together inside the microwave casing, that's essentially what's happening. It is a fire hazard and you should stop using the microwave immediately. As far as I know, there isn't a recall on that particular model (though there was on another similar Kenmore/Whirlpool model) so if it's out of warranty, you're out of luck.

Vibrating noise when cooking

In order to try to set your mind at ease I will have to explain the Basics on how a Microwave Oven Functions.
When a Microwave Oven is set to COOK ...START. It cooks at 100%. There is no lowering of the heat as with a Range ( Cook Top) Control. So in order to do the other things such as DEFROST, WARM, or anything other than 100% COOK. A COOK ON- COOK OFF system was utilized. To DEFROST, the Microve COOKS at 100% for 30% of the TIME, then IDLES for 70% of the TIME. COOK ON 30% of the TIME, COOK OFF 70% of the TIME = DEFROST This is why you can hear the CYCLE. More power is required during the ON CYCLE, thus the lower vibration. The Vibration occurs when the High Voltage Transformer is turned ON ( COOK ON).
The VIBRATION seems to have got louder with age. This is somewhat normal as there is a vibration from the High Voltage Transformer present every time the Microwave is used. screws and other metal parts seem to get loose with this vibration. There is no solution, unless you can tighten EVERY screw, nut, and bolt in the unit.

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.

High pitched hum/buzz

By high-pitched, you mean it is not that same frequency as when it's cooking? Is the tone near or the same as the beep you hear when you press a key? Please post a little more information so we can help better.
