With the full model number, chances are we could have helped you more.
If the cooktop lights recently failed, it may need circuit board repair.

Or it may be a failed hood TCO.

SOURCE: Kenmore 721 microwave fan turns on by itself

I have the exact same problem with my Kenmore Microwave model 721 that we bought in October of 2005. The Fan will just randomly turn itself on even when we are not cooking. It has been doing this for the last few months and is starting to become more frequent. There is no way to turn it off except to unplug it for several hours.
Was there a recall for this defect ?

Have Kenmore microvave and the vent starts on its own


Actually, that's a feature! If you cook much on the range (stove) beneath the microwave, the heat will cause the microwave bottom to heat up quite a bit (just touch it!), and the microwave will turn on it's exhaust fan in an attempt to save itself from burning up. It will shut off in about 15 minutes after you turn off the source of heat.
But if the fan comes on by itself even when the microwave is cool (or at least not hot), then you probably have a defective fan thermostat. This thermostat is located behind the control console on the inside bottom of the microwave.

My fan kicked on by itself and won't shut off


Hi,

The over the range microwave hood has a heat sensor in it. If it senses hot temperatures from cooking below it will turn the fan on. The fan will turn off once it cools down, this is to protect the microwave controls from damage.
