Ice Maker
Servicing Wire Harness
To remove wiring harness, depress retaining tab and
pull plug free.
To avoid property damage, always test for water leaks
after repair or replacement of the water valve. Do not
over tighten connection to household water supply.
Dual Water Valve
The dual water valve has two solenoids. When the tan
encapsulated solenoid is energized the amount of wa-
ter allowed to enter ice maker mold is directly propor-
tional to the length of time the water valve switch is
held closed by the timing cam.
Inside the valve is a flow washer which acts as a water
pressure regulator. Proper ice maker fill is 140 cc ±
10cc at 7.5 seconds of water fill at an inlet pressure
ranging from 20 to 120 PSI (1.4 to 8.2 bar).
When the light blue encapsulated solenoid is ener-
gized water flows through the coiled water tank to the
cavity spickett.
The water flow rate is to be 1.7 to 3.5 liter per minute
with 20 to 120 PSI (1.4 to 8.2 bar) pressure drop
across valve.
The valve also incorporates a 80 mesh screen water
strainer.
Wiring Harness
A one-time thermal fuse micro device 170° F is incor-
porated into the ice maker wiring harness to protect
the plastic liner from melting if the ice maker should
overheat. The thermal fuse is spliced into the red wire
of the ice maker harness. The thermal fuse is a 170°
F (78° C) nonresettable fuse. A "No Ice" complaint
could be caused by excessive heat. Replacing only
the wiring harness will only temporarily solve the prob-
lem. The ice maker thermostats should also be re-
placed
