THE DOOR LOCK SOLENOID & DOOR LATCH SWITCH

The door lock solenoid operates on a 120-volt pulse from the electronic control board. When the door is in the unlocked position, the plunger is extended. When the door latch switch is open, the control senses that the door is un- locked. When the door latch switch closes, the control senses that the door is locked. The door latch switch, mounted on the solenoid bracket, is in the N.O. (normally-open) position. During

the self-clean cycle, the control board sends a 120-volt pulse to the solenoid windings, which pulls the plunger in, and moves the latch ac- tuator rod to lock the oven door. The move- ment of the rod also actuates the door latch switch and closes it. When the self-clean cycle is over, the control board sends a 120-volt pulse to the solenoid, the plunger is pushed out, the latch actuator rod releases the door, and the door latch switch opens.
