Wine cooler shows E2 and may run continuously or shut down cooling unexpectedly.

Safety warning: Always disconnect power before accessing internal components. Evaporator fins can be sharp; wear cut-resistant gloves.

Diagnostic steps:

• 1. Power cycle: Unplug the unit for 5–10 minutes, then plug back in. If E2 reappears, proceed.
• 2. Access the evaporator area: Remove interior shelves and the rear inner panel to expose the evaporator coil. On many Electrolux wine coolers, the evaporator sensor is clipped directly to the coil or mounted in a small well near the coil.
• 3. Inspect sensor placement: Ensure the sensor is firmly clipped to the coil or seated in its holder. A loose sensor can cause incorrect readings and trigger E2. Re-secure if necessary.
• 4. Check wiring: Look for ice damage, corrosion, or broken insulation on the sensor wires. Gently tug on the connector to ensure it is fully seated.
• 5. Test the sensor: With the unit unplugged, disconnect the sensor and measure resistance. Compare to Electrolux service data if available; as a rule, resistance should change smoothly with temperature (higher resistance when colder). An open or shorted reading indicates a bad sensor.
• 6. Replace the sensor: If faulty, unclip the old sensor, route the new one along the same path, and secure it away from the fan blade. Reconnect to the harness and reinstall the rear panel.

Professional help: If the sensor tests good but E2 persists, the main control board's sensor circuit may be defective and should be diagnosed and replaced by a professional.
