Wine cooler display shows E1 and cabinet is not cooling or cooling poorly.

Safety first: Unplug the wine cooler from the mains before removing panels or touching wiring. Use insulated tools and avoid working on live circuits.

• Power reset: Disconnect power for 5–10 minutes, then reconnect. If E1 returns, continue with checks.
• Locate the cabinet NTC sensor: On most Gorenje wine coolers, the cabinet temperature sensor is clipped to the evaporator cover or mounted on the rear interior wall behind a small plastic cover. Remove interior shelves and the plastic cover carefully.
• Inspect the sensor and wiring: Look for broken insulation, pinched wires, or corrosion at the connector. Reseat the connector to the sensor and to the main PCB (usually behind the rear service panel).
• Measure sensor resistance: With the unit unplugged, disconnect the sensor from the harness and measure resistance with a multimeter. At room temperature (~25°C), most NTC sensors should read between 5–20 kΩ (check Gorenje service data if available). If the reading is open (OL) or near 0 Ω, the sensor is faulty.
• Check continuity of harness: Measure continuity from the sensor connector to the PCB connector. Repair or replace any damaged wiring.
• Replace the sensor: If resistance is out of spec, install a new Gorenje-compatible cabinet NTC sensor, route the lead away from sharp edges, and secure it in the original clip or bracket.
• Test operation: Restore power, clear the error by power-cycling, and monitor temperature and display for at least 30–60 minutes.
