Abstract
A simple, highly reliable automatic motor driven oven door latch for an oven self-cleaning operation. To ensure that the motor has operated correctly and has not stopped in a null position, the motor is provided with a start pulse and the location of the latch or locking member of the latching mechanism is monitored to guarantee that the locking member has moved to the correct position. If the locking member has not moved to the correct position, then the motor is provided with another start pulse and the location of the latch or locking member of the latching mechanism again is monitored to again ensure that the locking member has moved to the correct position. This sequence can be repeated on opening and closing of the latching mechanism a desired number of times to guarantee that the locking member has moved to the correct position when locking or releasing the oven door.
