Display shows rd or RD; refrigerator may not cool properly, and you may hear a repeated clicking sound.

Safety first: Unplug the refrigerator before accessing internal air ducts.

Step 1 – Locate the damper:

• The Refrigerator Air Damper is usually located between the freezer and fresh food compartments, often behind a cover at the top rear of the refrigerator section.

Step 2 – Inspect for ice or obstruction:

• Remove the damper cover.
• Check for ice buildup or foreign objects blocking the damper door.
• Defrost any ice with a hair dryer on low, keeping it moving.

Step 3 – Test damper operation:

• With the unit unplugged, gently move the damper door to see if it is jammed.
• Inspect the damper motor and gears for damage.

Step 4 – Replace the damper assembly if faulty:

• Disconnect the damper wiring harness.
• Remove mounting screws and install a new Refrigerator Air Damper Assembly.
• Reconnect wiring and reassemble covers.

Note: If rd persists after damper replacement, the Main PCB may not be controlling the damper correctly and should be checked by a technician.
