Wine cooler runs continuously and gets very cold; some bottles may freeze even at moderate setpoints.

Safety warning: Overcooling can damage wine. Adjust settings and correct faults promptly.

• Verify temperature setting: Ensure the setpoint is not at the lowest possible value. Increase the set temperature and observe if the compressor cycles off.
• Inspect door seal: Check the gasket for gaps or damage. Close the door on a sheet of paper at several points; if it pulls out easily, the seal is weak. Replace the "Door gasket" if needed.
• Check sensor accuracy: Place an accurate thermometer inside the cabinet. If the actual temperature is much lower than the display, the "Cabinet temperature sensor" is likely faulty and should be replaced.
• Control board relay: If the compressor never shuts off even when the display shows the set temperature, the compressor relay on the "Main control board" may be stuck closed. Replace the board.
