Wine cooler interior is too cold; bottles or labels may show signs of freezing even at moderate set temperatures.

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

• Verify settings: Confirm the set temperature is appropriate for wine storage and that any "super" or rapid-cool modes are off.
• Check sensor placement: Remove the interior sensor cover and ensure the NTC is not in direct contact with the evaporator or a cold air outlet. Reposition if necessary.
• Test sensor: Measure the NTC resistance and compare with expected values. Replace if readings suggest a short (very low resistance).
• Inspect control board: If the compressor runs continuously even when the interior is very cold, the compressor relay may be stuck closed. Replace the main PCB via a technician.
