Wine cooler display shows E1 and the unit does not cool properly or runs continuously.

Safety first: Unplug the wine cooler from the mains before removing any panels. Do not work on live circuits.

• Power reset: Disconnect power for 5–10 minutes, then reconnect. If E1 returns, continue.
• Access the cabinet sensor: On most Candy wine coolers, the cabinet NTC is clipped to the evaporator cover or mounted on the rear liner inside the cooled compartment. Remove the internal shelves and the rear plastic cover (usually a few screws).
• Inspect the sensor: Look for a small probe with two wires (often white or blue). Check for cuts, pinched wires, or corrosion at the connector.
• Check connections: Follow the sensor harness to the main control board (usually behind the rear service panel or under the top cover). Reseat the plug firmly. Clean any oxidation with electrical contact cleaner.
• Basic resistance check (for advanced DIYers): With the unit unplugged, disconnect the sensor from the board and measure resistance with a multimeter. At room temperature (20–25°C), most Candy NTCs read roughly 5–15 kΩ. If the reading is open (OL) or near 0 Ω, the sensor is faulty.
• Replace the sensor if faulty: Order a compatible "Candy cabinet NTC temperature sensor" using the model number from the rating plate. Clip the new sensor in the same position and route the harness away from moving parts and sharp edges.
• If sensor tests OK: The fault may be on the main PCB. Inspect the board for burnt components or cracked solder joints. If damaged, replace the "Main control board (PCB)" or contact a qualified technician.
