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, remove restrictions in supply line or level 
icemaker or refrigerator. Remove obstructions to air flow at fill end 
so it freezes first. 

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 

If cubes are small, check fill and level. Check if fill cup is displaced 
and blocking ice. Fix fill cup or 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 

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 mold 

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

Leaky water valve 

Tighten connections or replace water valve 

Temperature Problems 

Action 

Freezer too warm 

Adjust freezer setting 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 Thermal Cut-Out (no continuity through 
icemaker with ejector out of park) 

Replace icemaker and look for cause 

Open thermostat (won't close below 15 F) 

Replace icemaker 

Closed thermostat (won't open above 48 F) 

Replace icemaker 

Thermostat out of calibration 

Replace icemaker 

Heater not staked in mold 

Replace icemaker 

Won't cycle test with power available 

Replace icemaker 

Won't eject ice with power available 

Replace icemaker
