Refrigerator not cooling but freezer is working normally; fresh food section is warm while freezer remains cold.

Safety first: Unplug the appliance before removing interior panels.

Step-by-step:

• Check temperature settings: Ensure the refrigerator setpoint is not accidentally set too high or to OFF.
• Listen for fan: Close the door for a minute, then open and listen for the refrigerator fan. If silent, the fan may be faulty.
• Inspect air vents: Make sure vents between freezer and refrigerator are not blocked by food packages.
• Access damper: Remove the cover over the air inlet (usually at the top or rear of the refrigerator compartment). Inspect the damper flap for ice or mechanical damage.
• Clear ice: If the damper is frozen, defrost the area gently with warm air and dry thoroughly.
• Replace components: If the damper motor or fan does not operate when commanded (advanced testing), replace the Liebherr air damper assembly or refrigerator fan as needed.
