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.
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.
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.
Some refrigerators use an infrared beam to sense the level of ice in the ice bucket. When the ice level reaches the top of the bucket, it interrupts the infrared beam. The control board then shuts off the ice maker. When the ice level drops below the beam, the control board signals the ice maker to make more ice. If the ice level control board fails, the ice maker will stop making ice. Ensure that the ice level control board is getting power. If the ice level control board is getting power, but the ice maker won’t work, replace the ice level control board.
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.
EveryDrop Ice & Water Refrigerator Filter 3 reduces 66 contaminants, including lead and mercury, asbestos, and industrial chemicals. Each filter provides 200 gallons of filtered water and should be changed every 6 months to ensure proper contaminant removal and flow rate. NSF certified.
