ICEMAKER
1. Grasp 1 thermostat clip and pull out.
2. Press in new thermostat. Verify pins are
properly indexed. Electrical assembly
does not need to be removed.

new mold support. Use new thermal
bonding material.
Wiring Harness
Remove wiring harness by pressing
retaining tab and pulling forward.
Water Valve
Water valve has 1 solenoid. Valve has 80
mesh screen water strainer. When solenoid
is energized, the amount of water entering
icemaker mold is directly proportional to
length of time water valve switch is held
closed by timing cam. Inside valve is a flow
washer which acts as a water pressure
regulator. Proper icemaker fill is 140cc ±
10cc at 7.5 seconds of water fill at an inlet
pressure ranging from 20 to 120 PSI (1.4 to
8.2 bar).
Wire Harness
A non-resettable thermal fuse micro device
170° F (78°C) is spliced into black wire of
ice maker wiring harness. Excessive heat
can cause no ice production.
wiring harness will only temporarily solve
problem. Replace ice maker thermostats.
