Abstract

A microcontroller-based control circuit is provided for an appliance. The appliance includes an access door and an access door actuated switch operated between open and closed postures. The microcontroller monitors the operating condition of the access door actuated switch. If the access door actuated switch has not been cycled between an open and closed posture since the completion of a cycle of operations, a new cycle will not be allowed to start.
