Liebherr ice maker error E3; ice production intermittent and fan near ice maker runs at high speed

Safety first: Unplug the appliance before removing panels or fan covers.

• Inspect for frost: Remove the ice bin and inspect the area around the ice maker fan grille. Look for heavy frost or ice blocking airflow.
• Manual defrost: If frost is present, turn off the appliance and allow it to defrost completely. Use towels to catch water. Do not use heat guns or hair dryers inside the cabinet.
• Check fan movement: Once defrosted, spin the fan blades gently by hand (if accessible). They should rotate freely without scraping. Remove any debris.
• Listen for fan operation: Restore power and close the door. After a few minutes, listen for the fan starting. If it does not run or makes grinding noises, the fan motor is likely defective.
• Replace fan if needed: Replacing the ice maker compartment fan typically requires removing interior panels and should be done by a qualified technician.
