Display shows E2 and unit may overcool or not cool properly

Safety: Disconnect power before accessing the evaporator compartment or control board.

• Locate the evaporator: Remove interior shelves and any rear interior panel inside the wine cooler to access the evaporator coil area (behind a plastic or metal cover).
• Find the sensor: The evaporator thermistor is usually clipped to the evaporator tubing or mounted near the coil in a small plastic housing.
• Check mounting: Ensure the sensor is firmly attached to the evaporator coil or bracket. A loose sensor can cause incorrect readings and trigger E2.
• Inspect wiring: Trace the thermistor wires from the evaporator area to the main control board. Look for breaks, corrosion, or loose connectors. Reseat the connector on the board.
• Test the thermistor: With the unit unplugged, disconnect the thermistor and measure resistance. Compare to the GE spec chart for the approximate evaporator temperature (often colder than cabinet temp). Replace the thermistor if readings are open, shorted, or far off spec.
• Control board check: If the thermistor and wiring are good but E2 remains after a power reset, the main control board may not be reading the sensor correctly and will likely need replacement.
