Water curtains may need to be replaced if the pins are cracked or broken, or the magnet is missing. The water curtain serves as a trigger for the ice machine to initiate the freeze cycle or terminate the harvest. As ice falls off of the evaporator, the water curtain opens, breaking the proximity switch between the magnet and bin switch. When the ice machine is full, the curtain is held open, signaling to the control board to shut down.
