Diagnostics show E11; damper may be stuck; refrigerator section too warm or too cold.

Safety first: Unplug the refrigerator before removing interior covers.

Steps to resolve:

• Locate the damper: Usually in the upper left or right rear of the fresh food compartment, behind a vented cover.
• Check for ice: Remove the cover and inspect for ice buildup around the damper door. If present, unplug the unit and allow it to defrost fully.
• Inspect damper door: Manually move the door (with power off). It should move freely and close fully. If broken or jammed, the damper assembly must be replaced.

After defrosting and reassembly, restore power and monitor temperatures. If E11 returns or airflow remains incorrect, the damper motor or control board is likely faulty and should be serviced by a technician.
