When the solenoid plunger extends, two things happen (see Figure 4-30). As the latch solenoid
locks the door, it also activates the two door latch switches. Both door switches are normally-open
switches. As the solenoid moves to lock the door, the switches toggle, and:
a) Open the oven light circuit so that the light cannot be operated during the Clean function.
b) Provide a logic circuit for the electronic board to indicate that the door is locked and that
the Clean cycle can continue.
