Wine cooler runs continuously without cycling off; temperature may be correct or slightly low.

Safety: Disconnect power before adjusting hinges or replacing sensors.

• Check setpoint: Ensure the temperature is not set unnecessarily low. Raise the setpoint slightly and observe if the compressor cycles off.
• Inspect door alignment and gasket: Adjust hinges so the door closes squarely. Replace a damaged gasket.
• Test temperature sensor: If the cabinet is at or below the set temperature but the compressor keeps running, test the cabinet NTC sensor and replace if out of range.
• Control board evaluation: If the sensor is good and there are no air leaks, the main control PCB may not be interpreting the sensor correctly and may need replacement.
