This type of failure normally indicates that you have a stuck key on the membrane keypad. In rare instances, it could be caused by a failed electronic control board. I recommend replacing the control panel insert with membrane switches part number 154433701. It costs $130.16 not including tax shipping and handling from the Sears PartsDirect website.

This should fix your problem. If the problem continues after this membrane keypad is replaced, then the electronic control board would need to be replaced as well. This is unlikely but remotely possible.

If you need more help, resubmit your question with additional details.
