Display shows rd; fresh food section may be too warm or too cold; airflow between compartments may be restricted.

Safety first: Unplug the refrigerator before removing interior covers or working near the damper assembly.

Step 1 – Locate the damper:

• The damper is typically located at the top left or top rear of the fresh food compartment, behind a vented cover.
• Remove shelves as needed to access the cover.

Step 2 – Inspect for blockage:

• Remove the damper cover.
• Check for ice buildup, food packaging, or debris obstructing the damper door.
• Gently defrost any ice with a hair dryer on low, keeping it moving.

Step 3 – Check damper operation:

• With the unit plugged in and running, observe whether the damper door opens and closes when temperature settings change.
• If the door does not move or makes grinding noises, the damper assembly may be faulty.

Step 4 – Replace damper assembly:

• Unplug the refrigerator.
• Disconnect the wiring harness from the damper motor.
• Remove mounting screws or clips and take out the damper.
• Install the new damper assembly, reconnect wiring, and reinstall covers.

When to call a technician: If rd persists after damper replacement or if wiring to the control board is suspect, professional diagnostics are recommended.
