Wine cooler runs constantly and is too cold; bottles may be frosting or labels damp.

Safety first: Disconnect power before accessing sensors or the control board.

• 1. Verify settings:
  • Check that the set temperature is appropriate for wine storage and that SuperCool or similar boost modes are off.
• 2. Check door seal:
  • Inspect the door gasket for gaps, tears, or debris.
  • Close the door on a sheet of paper; it should hold firmly all around.
• 3. Inspect cabinet sensor:
  • Locate and visually inspect the cabinet temperature sensor for damage or dislodging.
• 4. Power reset:
  • Unplug for 10 minutes, then restore power and monitor behavior.
• 5. If overcooling persists:
  • The sensor may be out of range or the control relay stuck closed.
  • Replacing the cabinet temperature sensor is the first step; if that fails, the main control board likely needs replacement by a technician.
