Water Valve
The unit uses a 120VAC valve to supply water to the
ice maker. 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. Verify water supply line is ON, water
pressure is not below 20 psi, valve is fully open.
Clear restrictions by fully closing and opening valve.
Dislodge sediment (if necessary, remove valve),
make sure that the 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.
To access the water valve:
1. Open door and remove shelves and drawers.
2.
Remove upper and lower water tank covers
(see water tank section, page 45).
3.
Disconnect water lines, top and bottom wiring
harnesses, and ground wire.
4. Repair or replace water valve.
5. Reverse procedure to reinstall.
WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power to unit using power
switch before servicing. Wires removed during disassembly must be replaced on proper terminals to insure
correct earth ground and polarization. After servicing, reconnect power using power switch.
