WARNING

To avoid risk of electrical shock that can cause death or severe personal injury, disconnect unit from power before

servicing unless tests require power. Discharge capacitors through a 10,000-ohm resistor before handling. Wires

removed during disassembly must be replaced on correct terminals to ensure proper grounding and polarization.

Water Fill Adjustment

Turning the water level adjustment screw moves the

contact point in relationship with the contact ring

segment upon which it rides. Because the contact ring

is tapered, movement of the contact point causes

variation in the length of time that the water valve is

energized.

• Turning screw clockwise decreases fill time; turning

screw counterclockwise increases fill time.

• One half turn equals 20 cc or 1.2 seconds. A full turn

equals 40 cc or 2.4 seconds.

CAUTION

Maximum adjustment is one full turn in either direction.

Additional rotation can damage the module.

If water valve adjustment screw falls out, put it back

in and turn it until the holes align as shown below.

Area

When small hole is centered in larger hole, water

fill time is 7.5 seconds (normal).

Water Problems

Water quality can cause ice makers to fail, to flood, or

produce unacceptable cubes. If mineral content or

sand is a problem, the screen in the fill valve can clog

and restrict water flow. A particle of sand can prevent

the valve from seating properly.

Symptoms of clogging include small crescents (or no

ice). Symptoms of a dirty valve include flooding of the

ice container when the water valve does not close.

Mineral contact can also lime up the mold, causing
