Wine cooler shows E2 and may run continuously or not cool correctly; temperature display may be inaccurate.

Safety first: Disconnect power before accessing internal components. Sharp metal edges are present around the evaporator area.

E2 typically points to an evaporator temperature sensor issue in Café wine coolers.

• Step 1 – Confirm airflow and frost: With the unit running (before disconnecting power), check if the evaporator fan is running and if there is heavy frost on the back wall. Then unplug the unit.
• Step 2 – Access evaporator area: Remove interior shelves and the rear interior panel of the wine compartment (usually held by screws). Behind it you will see the evaporator coil and sensor clipped to the tubing or mounted nearby.
• Step 3 – Inspect sensor and wiring: Locate the small probe or bullet-style sensor attached to the evaporator. Check for broken insulation, corrosion at the connector, or a sensor that has fallen out of its clip.
• Step 4 – Test sensor: Disconnect the sensor from its harness and measure resistance with a multimeter. Compare to Café specifications for the evaporator thermistor at the current temperature. Replace if open, shorted, or far out of spec.
• Step 5 – Replace evaporator sensor: Install a new Café-compatible evaporator thermistor. Clip it securely to the evaporator tubing in the same location as the original to ensure accurate readings.
• Step 6 – Inspect control board: If the sensor tests good but E2 persists, inspect the main control board for burnt components or loose sensor connectors. Reseat connectors; replace the board if damage is evident or if diagnostics confirm a board fault.

Reinstall the interior panel and shelves, restore power, and monitor operation for several hours.
