Icemaker Troubleshooting Chart
Ice Problems
Action
Jammed cubes (small or oversized cubes) Adjust fill level or level icemaker or refrigerator
Hollow cubes
Adjust for low fill or remove restrictions in supply line. Level ice
maker or refrigerator. Remove obstructions to air flow at fill end
so it freezes before thermostat end.
Ice build up on ejector blades
Usually caused by hollow cubes. See hollow cubes above. Remove
icemaker to thaw out.
Cubes falling back into mold during ejection
Ifsomecubes aresmall, check fill and level. Check if fill cup is
displaced and blocking ice. Fix fill cupor replace icemaker.
Cubes falling over back of icemaker
Check if fill cup is displaced and blocking ice. Fix fill cup or
replace icemaker.
Power Problems
Action
No power to icemaker 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 icemaker
Look for obstructions in water valve or fill tube.
Insufficient water to icemaker (with correct fill
time)
Check for restrictions in supply line and valve, especially saddle
valves.
Clogged water valve
Clean or replace water valve depending on type of valve.
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. /
I Low water fill volume
Adjust water fill screw, clear obstructions in supply line or supply 1
valve, or replace water valve.
Excessive water fill volume
Adjust water fill screw, reduce water pressure, or replacewater
valve.
Water overflows fill cup Reposition fill tube in fill cup or remove obstruction in fill cup.
Water overflows mold
Adjust water fill screw, level icemaker or refrigerator, reduce wa
ter pressure, or replace water valve or icemaker.
Leaky water valve
Tighten connections or replace water valve
Temperature Problems
Action
Freezer too warm
Adjust freezersetting or repair refrigerator
Icemaker Problems
Action
Raised shut-off arm
Lower shut-off arm to ON position
Broken or bent shut-off arm
Repair arm or replace icemaker
Shut-off arm stuck or obstructed
Remove obstruction
Icemaker not level
Check level of refrigerator first, then level icemaker
Can't level icemaker
Level refrigerator first then try again
Open thermostat (won't close below 17" F) Replace Icemaker
Closed thermostat (won't open above 32" F)
Replace Icemaker
Thermostat out of calibration
Replace Icemaker
Heater not staying in mold Replace Icemaker
Won't cycle test with power available Replace Icemaker
Won't eject ice with power available
Replace Icemaker
