To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit, unless test
procedures require power to be connected. Discharge capacitor through a resistor before attempting to service.
Ensure all ground wires are connected before certifying unit as repaired and/or operational.

to eliminate bad taste, odor, and visible
contaminates. Mineral content or sand can
restrict screen in water fill valve or particles
of sand can keep valve from seating
properly.
If water valve does not operate properly,
the following could occur: no ice production,
small or hollow ice cubes, flooding of ice
container. Mineral content can cause lime
build up in the mold, wicking of water over
the mold and poor cube release. Mineral
content can also restrict saddle valves. Verify
water supply line is “ON”, water pressure is
not below 20 psi, saddle valve
is fully open clear restrictions by fully closing
and opening valve to dislodge sediment
(if necessary, remove valve and enlarge
pierced hole to 3/16” diameter with a drill
and reinstall saddle valve) ensure water
line to unit is not pinched/kinked/ clogged,
ice is not present in inlet tube blocking
water flow, water pressure is not above 120
psi. Water fill can be increased by turning
the adjustment screw counterclockwise
and decreased by turning the screw
clockwise. One half turn will adjust the fill
by approximately two thirds of an ounce.
If supply is OK replace water valve. If no
voltage is present, verify harness. If OK,
replace module.
