F7 displayed; compressor may not run; unit remains warm despite power being on.

Safety first: Disconnect power and allow the compressor area to cool before touching components.

Steps:

• 1. Check ventilation: Ensure there is adequate clearance around the wine cooler and that ventilation grills are not blocked by cabinets or dust.
• 2. Clean the condenser: Remove the rear lower cover and gently vacuum or brush dust from the condenser coils. A clogged condenser can cause overheating.
• 3. Inspect condenser fan (if present): Verify that the fan spins freely and is not obstructed. Replace the fan motor if seized or not running when powered.
• 4. Check overload protector: The overload device is mounted on the compressor terminals. Inspect for burn marks or deformation. Replacement should match the original Liebherr specification.
• 5. Allow cooling time: Leave the unit unplugged for 30–60 minutes to let the compressor cool, then reconnect power and observe operation.

Important: If F7 recurs quickly and the compressor is extremely hot to the touch, the compressor may be failing internally and requires professional diagnosis and likely replacement.
