This is an energized circuit. Shock can occur
if not tested properly. Testing is to be done
by a qualied service technician.
12.13 Wiring
Refer to the wiring diagram supplied with the unit you
are working on, and make sure all wiring connections
are correct and tight. There are 4 wires coming from
the ice maker.
BLACK: Connected to incoming hot from AC power
source. This could be a split wire at the AC BLACK at
the circuit board or a separate power cord.
WHITE: Connected to either side of the water valve
and will split at the valve and hook-up to the incoming
WHITE from the power source.
GREEN/YELLOW: Connected to chassis ground.
BROWN: Connected to either side of water valve.
Water Valve (Single)
Water Valve (Dual)
Refer to the wiring diagram supplied with the unit you
are working on, and make sure all wiring connections
are correct and tight. There are 4 wires coming from
the ice maker.
BLACK: Connected to incoming hot from AC power
source. This could be a split wire at the AC BLACK at
the circuit board or a separate power cord.
WHITE: Connected to either side of the water valve
(W2) and will be wired in series to water valve (W1).
From the water valve it will be routed to (J1) on the in-
terface module and split to the incoming WHITE from
the power source.
GREEN/YELLOW: Connected to chassis ground.
BROWN: Connected to either side of water valve
(W2)
BLUE: Connected to either side of water valve (W1).
This is the start of an ejection
cycle. The thermostat switches to
its closed position after being suf-
ciently cooled by the ice in the
mold. The mold heater and motor
are now energized. The ejector
blades begin to turn.
This is a freeze cycle. The mold
is lled with water. The thermo-
stat is open. All components
are de-energized.
