COMPONENT DESCRIPTION: Control Box
Circuit Board: Controlling the ice machine
through sensors and relays. The sensors are:
ice level, and water level. The relays are for
the gear motor (with a built in time delay to
clear the evaporator of ice when the unit turns
off) and for the liquid line valve.
Transformer: Supplies low voltage to the
circuit board.
On/Off Switch: Manual control for that side
of the machine.
Reset Switch: Manual reset. Glows when
the unit shuts off from the ice discharge chute
being overfilled (pressure of the ice opening
the microswitch at the top of the chute).
