The emitter board emits an infrared beam.
When the eye on the receiver board sees
the beam a circuit is completed indicating
the ice bin is in place and not full. This sig-
nal is sent to the control board and the ice
maker is energized. If the beam is not seen
by the receiver board, the control board
shuts off the ice maker.
