Jammed cubes (small or oversized cubes) Adjust ll level or level ice maker or refrigerator
Hollow cubes Adjust low ll or remove restrictions in supply line
Level ice maker or refrigerator
Remove obstructions to air flow at ll end so it freezes before
thermostat 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 Check if ll cup is displaced and blocking ice
Fix ll cup or replace ice maker
Cubes falling over back of ice maker Check if ll cup is displaced and blocking ice
Fix ll cup or replace ice maker
Power Problems Action
No power to ice maker at connector socket Determine discontinuity by tracing power
No power to water valve Determine discontinuity by tracing power
Water Problems 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 ll tube
Clogged water valve Clean or replace water valve depending on type
Insufcient water to ice maker
(with correct ll 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 ll volume Adjust water ll screw, clear obstructions in supply line or supply
valve, or replace water valve
Excessive water ll volume Adjust water ll screw, reduce water pressure, or replace water
valve
Water overflows ll cup Reposition ll-tube in ll cup or remove obstruction in ll cup
Water overflows mold Adjust water ll screw, level ice maker or refrigerator, reduce
water pressure, or replace water valve or ice maker
Leaky water valve Tighten connections or replace water valve
