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 (see Figure 4-31). This unlocks the door and toggles the door latch switches to their normal state.
