Wine cooler shows E9 and interior temperature cannot be adjusted or remains at one extreme.

Safety: Disconnect power before removing interior panels or accessing dampers.

Steps to troubleshoot E9:

• Identify zones: On dual-zone models, note which zone is not responding to temperature changes (upper or lower).
• Check airflow: Feel for airflow between zones. If one zone is much colder and the other is warm, the damper may be stuck closed or open.
• Access the damper assembly: Remove the interior divider or rear panel where the two zones meet. Locate the small damper door and motor assembly.
• Inspect damper door: Look for broken plastic, obstructions, or ice preventing movement. Clear any debris and gently free the door if stuck.
• Test damper motor: With power restored and a temperature change commanded, listen/feel for damper motor movement. If silent and no movement, test for voltage at the motor connector.
• Replace damper motor: If voltage is present but the motor does not move, install a new Frigidaire damper motor assembly. Ensure the door is correctly aligned.
• Check harness: If no voltage is present, inspect the communication harness between zone boards for damage or loose connectors.

Professional help is recommended if harness or control board issues are suspected.
