Refrigerator Ice Maker Keeps Freezing Up – How To Fix?

I need help with my refrigerator ice maker. My 4 year old refrigerator ice maker constantly freezes up. It is a french door model made by Whirlpool. The problem is, the ice maker freezes up and the ice cubes do not drop. The water dispenser still works but not the ice. The ice does not dispense as the ice holding area forms into a large block of ice. The tray needs to be removed every 3 weeks and the ice removed for it to work again. What parts in my refrigerator can cause the ice maker to keep freezing up?

Parts for ice maker freezing upIce Maker Freezing Up  – Parts To Check

Freezer Temperature Is Too Cold
If the temperature is too cold in the freezer, the water can turn to ice too quickly. Simply turn the temperature in the freezer to the proper temperature setting. The FDA recommends your freezer temperature should be 0° F (-18° C).



Water Filter Issue
If the refrigerator water filter is clogged, this can cause water pressure issues. Water pressure problems can cause the ice maker to freeze up. Change the water filter.

High Or Low Water Pressure
Check the water pressure going into the refrigerator. If the pressure is too high or too low, the refrigerator ice maker may have issues with freezing. Water pressure over 120 PSI can cause the ice maker to freeze up.

Water Line Positioned Incorrectly
If the water line (on certain ice makers) is pushed too far into the valve, this can cause a splashback affect which lets water into certain areas and freezes. NOTE: Sliding the refrigerator back into position and against the wall can cause the water line to be pushed further into the ice room and cause splashback. Check the water line for the proper positioning.

Defective Ice Maker
The ice maker works with a small motor and most times a small circuit board. If one of these components located in the ice maker itself fails, the ice maker needs to be replaced. If the ice maker fails to work, the issue of the ice maker freezing up can occur. Remove and replace the ice maker.

Water Supply Line Frozen
The water line that carries water from the valve to the ice maker can become frozen. This may be because the freezer temp is too cold or other various reasons. In some refrigerators, you may need to add a type of insulating piping material to insulate the water lines if they continue to be frozen. If you find water lines frozen, try defrosting the complete refrigerator or you can try the hair dryer method to defrost the frozen water line. Use caution when using the hairdryer. If the water lines continue to be frozen, turn the freezer temperature to a higher temp to try and keep the water lines from getting too cold.

Ice Fill Tube (or chute)
On most refrigerators there is an ice fill tube. This filling tube is seperate from the water lines but brings water to the ice maker. The ice fill tube may be behind the ice maker, you can slide out the ice maker to access it. Find out if the tube is frozen or not. If frozen, you can thaw it out in place with hot water using a baster or remove it from the ice maker and run it under hot water.

Faulty Water Inlet Valve
The water valve lets water flow into the refrigerator. This water goes to the ice maker. If the water inlet valve is faulty, it can overfill the ice cube area and freeze up. This will cause a frozen ice maker. Check the water inlet valve on the back of the refrigerator. Check it with a multimeter to see if the solenoid is in working order. If found to be faulty or leaking, remove and replace the valve.
