Action
Jammed cubes (small or oversized cubes) Adjust fill level or level ice maker or
refrigerator
Hollow cubes Adjust low fill or remove restrictions in supply
line
Level ice maker or
refrigerator
Remove obstructions to air flow at fill end so it freezes

end
Ice build-up on ejector blades
Usually
caused by hollow cubes
See
hollow cubes above
Remove ice maker, thaw
out
Cubes falling back into mold during
ejection
If some cubes are small, check fill level
Check if fill cup is displaced and blocking ice
Fix fill cup or replace ice maker
Cubes falling over back of ice maker Check if fill cup is displaced and blocking ice
Fix fill cup or replace ice maker

Ice Maker – No Water (AF
Models)
Action
No water to
refrigerator
Turn on supply
Look for obstructions in supply line or valve
No water to ice maker Look for obstructions in water valve or fill
tube
Clogged water valve Clean or replace water valve depending on
type
Insufficient water to ice maker
(with correct fill
time)
Check for restrictions in supply line and valve, especially saddle valves
Low water pressure at supply
Increase
water pressure to 20 – 120 PSI
Low water pressure at water valve Look for restrictions in
line
Excessive
water pressure Install pressure regulator and set to 60 PSI
Low water fill volume
Adjust water fill screw, clear obstructions in supply line or supply valve,
or replace water valve
Excessive
water fill volume Adjust water fill screw, reduce water pressure, or replace water valve
Water overflows fill
cup
Reposition fill-tube in fill cup or remove obstruction in fill
cup
Water overflows

Adjust water fill screw, level ice maker or refrigerator, reduce
water
pressure, or replace water valve or ice maker
