The Oven Door Latch Assembly - Whirlpool GBD307PD Manual

THE OVEN DOOR LATCH ASSEMBLY

The door latch solenoid operates on a 120-volt
dc pulse from the electronic control board.
When the solenoid plunger is retracted, the
oven door is in the "unlocked" position. When
the solenoid plunger is extended, the oven
door is in the "locked" position. When the door
lock switch is open, the control senses that the
door is "unlocked." When the door lock switch
closes, the control senses that the door is
locked. The door lock 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 dc pulse to the solenoid
windings, which extends the plunger (pushes it
out), and moves the latch arm to lock the oven
door. The movement of the arm also actuates
the door lock switch arm, and closes it. When
the self-clean cycle is over, the control board
sends a 120-volt dc pulse to the solenoid, the
plunger is retracted (pulled in), the latch arm
releases the door, and the door lock switch
opens.
