Display shows dE and the ice dispenser or ice maker does not operate correctly.

Safety first: Unplug the refrigerator before accessing any wiring or components. Avoid using sharp tools to remove ice.

On many GE refrigerators, dE indicates a defrost system problem that can lead to frost buildup on the evaporator coil.

• Check for frost buildup: Remove freezer drawers/shelves and inspect the rear freezer wall. A thick, even layer of frost indicates the defrost system is not working.
• Manual defrost: As a temporary measure, unplug the unit, open doors, and allow it to defrost for 24 hours. Place towels to catch water. This may restore cooling for a short time but does not fix the underlying issue.
• Inspect defrost heater and wiring: Remove the rear freezer panel to expose the evaporator coil. The defrost heater is typically at the bottom of the coil. Look for burnt spots, broken glass tube (if glass style), or disconnected wires.
• Check defrost thermostat/bi-metal: The thermostat is clipped to the evaporator tubing. If it appears bulged or cracked, it should be replaced.
• Thermistor testing: GE uses thermistors to sense coil temperature. A failed thermistor can prevent defrost. Testing requires a multimeter and temperature chart; if readings are far off spec, replace the evaporator thermistor.
• Control board: If heater, thermostat, and thermistor test good, the main control board may not be initiating defrost. Board replacement is typically a level-4 repair and best left to a technician.
