When a residential refrigerator water dispenser functions normally but the automatic ice maker fails to produce ice cubes, the malfunction usually points to a closed icemaker power switch, a frozen water fill tube, or a faulty dual-solenoid water inlet valve. In many refrigerators, the water inlet valve features two separate electrical solenoids—one for the front door dispenser and one for the freezer ice maker; if the ice maker solenoid burns out, water will dispense through the door but fail to reach the ice mold. You can troubleshoot water flow easily by inspecting the fill tube. You can verify that your troubleshooting is successful when clearing fill tube ice, turning on the icemaker switch, or replacing a burnt-out water inlet valve solenoid restores normal ice harvesting.
