Wine cooler runs continuously and gets too cold; bottles may be colder than the set temperature.

Safety: Unplug the unit before accessing sensors or the control board.

Steps:

• 1. Verify temperature: Use an accurate thermometer to confirm actual cabinet temperature versus the setpoint.
• 2. Inspect cabinet sensor: Locate the NTC sensor in the compartment wall. Ensure it is not touching the evaporator or a cold air outlet, which can cause false low readings.
• 3. Test sensor resistance: Disconnect the sensor and measure resistance at known temperature. Replace if readings are out of spec or if the sensor is shorted.
• 4. Check control board relay: If the compressor relay is stuck closed, the compressor may run continuously. Inspect the board and replace if the relay is welded or the board is damaged.
• 5. Reassemble and test: After replacing components, monitor operation over several hours to ensure proper cycling.

Tip: Overcooling can dry out corks; resolve this issue promptly to protect your wine.
