DOOR LOCKING MECHANISM

The door lock assembly is located at the back side
of range.
The structural elements are as below.
1. When the oven control is programmed and started for
the Self clean and Lock out mode, PCB (Power control
board) chip operates the motor.
2. The cam moves the door hook connected to latch rod
from unlocked position to locked position (from locked
Position to unlocked position)
3. The cam activates the micro switch that causes the
motor to stop.
4. The locked status remains until the range temperature
drops to approximately 500F after end of the self clean
or lock out feature is reactivated. The motor operates to
unlock door at that time.
