The part(s) or condition(s) listed below for the symptom Refrigerator ice maker not working are ordered from most likely to least likely to occur. Check or test each item, starting with the items at the top of the page.
If the freezer temperature is above 10 degrees Fahrenheit (-12C), the ice maker will not produce ice cubes efficiently. The freezer temperature should be set between 0 and 5 degrees Fahrenheit (-18 to -15C) for the ice maker to work properly. If the freezer temperature is too high, ensure that the condenser coils are clear of debris and the condenser fan is working properly. In addition, check to see if frost has accumulated on the evaporator coils. If the evaporator coils are frosted over, part of the defrost system has likely failed.
The water inlet valve is an electrically-controlled valve that opens to supply water to the dispenser and ice maker. If the water inlet valve is defective, or if it has insufficient pressure, it won’t allow water to flow through. As a result, the ice maker won’t make ice. The valve requires at least 20 psi to function properly. Make sure that the water pressure to the valve is at least 20 psi. If the water pressure is sufficient, use a multimeter to check for power to the water inlet valve. If the water inlet valve has sufficient pressure and is getting power, but the ice maker won’t fill with water to make ice, replace the water inlet valve.
Refrigerator water inlet valve assembly with quick connect fitting . To disconnect the tube, push the white retainer fitting in while pulling on the tube. If the cold water is not coming out of the water dispenser, or if the ice maker won't dispense ice, the water inlet valve may be at fault.
One component of the ice maker assembly might be defective. Since many of the ice maker components are not sold separately, you may need to purchase and replace the entire ice maker assembly. Before replacing the ice maker assembly, check the water inlet valve, water line, and fan. If none of these parts are at fault, and the freezer temperature is at least 15 degrees Fahrenheit, replace the ice maker assembly.
Refrigerator icemaker kit, The kit includes the fill cup, 4 pin wire harness adapter, and tube. If the icemaker is not working, make sure the freezer temperature is around zero degrees Fahrenheit. If the refrigerator temperature is correct, the icemaker or water valve could be defective.
The home may have insufficient water pressure. The water inlet valve supplies water to the ice and water dispenser. The water inlet valve requires a minimum of 20 psi to function properly. Check the water flow and test the pressure to determine if it is at least 20 psi.
A clogged water filter can restrict the flow of water to the dispenser and prevent the ice maker from working properly. The water filter should be replaced about every six months to maintain proper water flow and ensure water quality.
GE MWF water filter reduces up to 94% of contaminants including lead, chlorine, and asbestos. Replace every 6 months.
If you have never installed this new style filter or your old filter was made by Culligan you may need the adapter to install it, see Related Items below.
