Symptom
Condensation or water droplets forming on the inside of the glass door.
Door Seal / Insulation or Humidity Issue
Symptom
Dual-zone Neff wine cooler: both zones show the same temperature and cannot be set independently.
Zone Control or User Interface Fault
Symptom
Dual-zone Neff wine cooler: upper zone cools correctly but lower zone is warm.
Lower Zone Airflow or Valve Control Fault
Symptom
Exterior of the wine cooler cabinet feels unusually warm, especially around the door frame.
Condenser Heat Dissipation / Mullion Heater Operation
Symptom
High-pitched whistling or whooshing noise from inside the wine cooler.
Refrigerant Flow or Airflow Noise
Symptom
Interior light does not turn on when the door is opened, but cooling works normally.
LED Light or Door Switch Failure
Symptom
Interior light stays on even when the door is closed, causing the cabinet to warm up.
Stuck Door Switch or Control Logic Fault
Symptom
Persistent beeping or alarm sound even though temperature seems normal.

Symptom
Wine cooler interior is too humid; labels peel and mold appears on corks.
High Humidity Inside Cabinet
Symptom
Wine cooler interior temperature fluctuates widely; some areas are much warmer or colder than others.
Poor Air Circulation / Fan Performance Issue
Symptom
Wine cooler is too cold; bottles or labels show signs of freezing even at moderate set temperatures.
Thermostat / Temperature Control Miscalibration
Symptom
Wine cooler makes loud humming or buzzing noise from the back.
Compressor or Condenser Vibration Noise
Symptom
Wine cooler not cooling at all; interior is at room temperature, but display and lights work.
