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

Safety: Unplug the unit before accessing sensors or PCB.

• Verify with thermometer: Place an independent thermometer inside to confirm actual temperature versus display.
• Check sensor placement: Ensure cabinet and evaporator sensors are firmly attached and not hanging in free air or touching very cold metal directly.
• Inspect wiring: Look for damaged sensor wires that could cause incorrect readings.
• Replace suspect sensor: If readings are clearly off, replace the cabinet NTC sensor with the correct mQuvée part.
• Control board: If freezing persists with a new sensor, the main control PCB may be misreading or stuck driving the compressor. Replace the PCB.
• Interim measure: Raise the set temperature a few degrees and monitor until permanent repairs are made.
