Ice Maker – Emitter /Receiver Boards
1. With the switch on the emitter board in the ON
position, the window covering the emitter beam is
opened.
2. With the switch on the emitter board in the OFF
position, the window covering the emitter beam is
closed.
3. With the ice bin installed it forces the receiver door
closed aligning a window in the door with the eye on
the receiver board.
4. When the ice bin is removed, the door opens and
blocks the signal from the emitter.
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 signal 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.
