•
The latch solenoid relay closes for 1 second, and provides a 120 VAC pulse to the latch
solenoid, which immediately locks the oven door.
•
When the oven temperature reaches 600˚, the oven door cannot be opened until the oven
cools down to below 550˚. At that point, the latch solenoid relay will close for just a second,
and provide a 120 VAC pulse to the latch solenoid. This unlocks the door and toggles the
door latch switches to their normal state.
•
As the latch solenoid locks the door, it also activates the two door latch switches. Both
switches are normally-open switches. The lower switch is closed when the solenoid moves
to lock the door, and provides a logic circuit back to the electronic control board to indicate
that the Clean cycle can safely continue.
•
The upper switch is held closed during normal operation to provide a circuit for the oven
light. However, when the Self-Clean cycle is operating and the solenoid closes, it opens
the switch, and deactivates the oven light circuit.
