Wine cooler is too cold; bottles near the back may partially freeze.

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

• Verify setpoint: Confirm that the temperature setting is not accidentally set too low.
• Check sensor placement: Ensure the cabinet NTC sensor is mounted in its original location and not touching the evaporator coil directly, which can cause overcooling.
• Test sensor: Measure resistance at known temperatures and compare to specifications. Replace if readings are off.
• Control board check: If the sensor is good but the compressor runs excessively, the compressor relay on the main PCB may be stuck. Replace the main control board if necessary.
• Reposition bottles: Avoid placing bottles directly against the rear wall where air is coldest; allow space for airflow.
