The Complete Ge Fridge Ice Maker Repair Guide: Step-by-Step Troubleshooting
If the ejector blades rotate but the tray remains dry, verify water delivery to the back of the cabinet. The primary water inlet valve, mounted behind the lower rear access panel, uses an electromagnetic solenoid coil to meter water into the freezing mold. This component requires steady hydraulic feed.
A low water pressure line causes incomplete fills, hollow crescent cubes, or valve cavitation. Household supplies feeding reverse-osmosis systems often drop below the required 20 to 120 PSI operating threshold. To isolate this, inspect the primary supply stop valve. Saddle valves installed on copper pipe frequently clog with mineral scale over time, starving the intake port.
Evaluate the primary filter cartridge next. A saturated carbon block creates severe line drop across the manifold. Remove the main filter and insert a dedicated water filter bypass plug into the manifold head. If cube production resumes immediately, the filter head or clogged media was throttling delivery. If pressure remains absent, test the solenoid coils for continuity using a multimeter set to ohms (Ω). A functional GE dual-solenoid valve should register between 180 and 500 ohms across its terminals. A reading of infinity indicates an open, burned-out coil requiring physical replacement.
