1. Water fill setting too low (less than 6.6 seconds) causing icemaker to cycle too early
and is evidenced by hollow ice cubes, ice build-up on the ejector blades, or water
freezing in the ice bucket. Increase fill setting by turning the adjustment screw
counterclockwise.
2. Water fill setting too high (more than 7.2 seconds) causing water to spill over into
the ice bucket or to form around the ejector shaft. Decrease fill setting by turning
the adjustment screw clockwise.
3. Water fill is correct but icemaker is not level. Level icemaker. In severe cases the
water will spill over the low end. In all cases the high end will produce small cubes
which are likely to cause jams and at the low end the cubes will be oversized and
may jam the ejector shaft.
4. Icemaker is not level because refrigerator is not level. Level unit first then level
icemaker.
The amount of water entering the icemaker mold is directly proportional to the length of
time the water valve is held open by the timing cam in the icemaker. Proper icemaker fill
is 120cc at 6.6 to 7.2 seconds of water fill at an inlet pressure ranging from 20 to 120 psi.
A flow washer inside the water valve acts as a water pressure regulator.
1. Check power to water valve. Unplug connector from water valve and connect a test
light or voltmeter to the two terminals of the cable supplying the water valve.
Manually start a test cycle of the icemaker. Close freezer door to close door switch.
At the end of the second revolution (6 minutes) the icemaker should send line
voltage to the water valve for approximately 7 seconds.
2. Water valve wire /connections loose/broken. Repair wiring.
3. Defective solenoid. Check solenoid coil (180-200 ohm). If shorted or open,
replace valve.
4. Screen water strainer at inlet end is clogged. On valves with threaded fittings, the
screen is removable for cleaning. On valves with Guest Fittings (quick connect
type) the screen is not accessible for cleaning and the valve must be replaced.
