Exterior of the wine cooler cabinet feels unusually warm, especially around the door frame.

Safety: Unplug the unit before cleaning the condenser.

Steps:

• Check ventilation: Ensure that built-in Neff wine coolers have the specified ventilation cut-outs and that freestanding units have adequate clearance.
• Clean condenser: Vacuum or brush dust from the condenser coils at the rear or base.
• Monitor temperature: A mildly warm frame is normal to prevent condensation. If it is too hot to touch, contact service to check for airflow or control issues.
