Wine cooler has power (lights/display on) but compressor and fan never start.

Unplug the unit before touching wiring.

• Confirm temperature setting: Ensure the set temperature is lower than room temperature so the unit should be calling for cooling.
• Check door switch: Some models inhibit cooling if the door switch is faulty. Press the door switch manually and see if the fan or compressor attempts to start.
• Inspect compressor connector: At the compressor, verify that the harness is fully seated on the start relay/overload assembly.
• Board relay check: Access the main control board and look for the compressor relay. Inspect for burn marks or cracked solder joints. If the relay is visibly damaged, replace the main control board.
• Sensor sanity check: If the board believes the cabinet is already cold due to a bad sensor, it may not start the compressor. Compare displayed temperature to an internal thermometer and replace the cabinet thermistor if readings are inaccurate.
