The wine cooler runs constantly and never seems to shut off, even though the temperature is acceptable.

Safety: Unplug the unit before testing sensors or adjusting door components.

• 1. Confirm actual temperature: Use a thermometer to verify that the interior is at the desired temperature.
• 2. Inspect door gasket and cabinet: Repair any leaks that allow warm air in.
• 3. Test thermistor: Replace if readings are off compared to the actual temperature.
• 4. Consider ambient conditions: If the cooler is in a very warm room, continuous running may be normal. Improve room cooling or ventilation if possible.
