Wine cooler is too cold; bottles or beverages are near freezing even at normal settings.

Safety: Unplug the unit before accessing sensors or the control board.

• Verify settings: Increase the set temperature and monitor for several hours to see if the interior warms.
• Check sensor placement: Ensure the cabinet temperature sensor is not touching the evaporator coil directly, which can cause false low readings.
• Test sensor: Measure resistance of the sensor at known temperatures. Replace if readings are out of specification.
• Inspect control board: If the compressor runs continuously regardless of temperature, the main control board relay may be stuck and should be replaced.
• Board replacement: Install a new OEM Kismile main control board if sensor replacement does not correct overcooling.
