Refrigerator and freezer both warm; compressor runs continuously but no cooling.

Safety first: Do not attempt to open the sealed system yourself; specialized tools and certification are required.

Step-by-step (owner checks):

• Condenser temperature: Carefully feel the condenser (rear grid or bottom coil) after the unit has run for 20–30 minutes. If it is completely cool, the sealed system may not be moving refrigerant.
• Frost pattern: If accessible, inspect the evaporator. Frost only on a small section indicates low refrigerant or restriction.
• Noise: Listen for unusual compressor noises (knocking, metallic sounds).

Action: Contact an authorized Liebherr service technician. Sealed system repairs involve refrigerant recovery, leak detection, and recharging and are not DIY tasks.
