Fan relay on circuit board stuck. Give it a tap (the relay), to free it up. Otherwise get the relay or driver transistor replaced. Easy fix. Take it to an electronic repair place, not the brand agent.(They,ll just replace the whole board).If this Item is under warranty you should not be wasting my time.:::Spiceweasel.au

One of 2 things are happening..One of the thermo protectors has a bad connection (Kenmore is good for these) or the Magnetron has a leak inside the control cavity causing a temporary short in the control.

My Kenmore microwave oven fan has been turning on and off, almost every hour. Sometimes 3 or 4 times in one hour. It's very random. Model No. 721-80593401 Serial No.503TA03208

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 ?

It is more than likely one of the door switches has malfunctioned, or there is a problem with the keypad control board.
