SOURCE: clock,timer and oven does not work on Kenmore gas Range

Unplug the unit and see if this will reset the board. If this doesn't work then replace the oven control board.

Let me know the model# and ill see if there are any thermal fuses. If not than most likely you will have to replace the EOC (Electronic oven control). Available at www3.sears.com

Call the manufacturer. Chances are it's a common problem and they already know about it.

I have the same toaster oven and my timer knob just broke 2 days ago. Go to SearsPartDirect.com website. They have a substitute timer knob.
