If the turntable does move as well it is likely the inverter (power) or the Magnetron itself.

My Whirlpool microwave, over the stove, stopped working when my son used it to heat his food and a heavy sound came out, like something exploded in it. When I check it, there was nothing broke. Everything works fine except that it does not heat. I will appreciate any help

Sounds like you've had a failure in the microwave portion of the unit.

Microwave not heating problems when the timer/controller board appears to function properly, are related to the following components -

1) Diode
2) Capacitor
3) Transformer
4) Magnetron

this is something you should probably call a repair technician for, due to the danger of the componentry.

Usually in ther case of this problem, even a technician will advise you to replace the unit, in the minds of cost effectiveness and safety...

Cheers,

The microwave does not heat up the food but everything works except the fact that it don't heat up the food

Hi!

The most common cause of the problem you described is a burned fuse. It is normally located inside the case, directly on a wire leading from the transformator to the magnetron. If you are not sure about those parts, please get a professional to fix the issue.

Good luck!

The microwave isn't heating/cooking on any setting but the turntable, light is working. What should I check before calling a repairman?

There is nothing more you can do, you have verified everything is working except it is not heating the food. The next step is have the repairman come in to isolate the cause.

Microwave Won't Heat Food

My Kenmore 721.63259301 would not heat items up so I came here and saw the parts required and was just about to order them when I checked the online owners manual and found this. FULL FIVE-YEAR WARRANTY ON
THE MAGNETRON For five years from the date of purchase, if the
magnetron in this Kenmore microwave oven
fails due to a defect in material or workmanship,
Sears will repair it free of charge.
My microwave has a manufacture date of July 2009 so I will be taking it right to the closest Sears repair center for a free repair. I suggest everyone do the same.
