Customer Questions and Answers for Air Damper Control (Refrigerator) by Whirlpool

This refrigerator air damper control is the motorized assembly that regulates how much cold freezer air enters the fresh food section, helping maintain even, accurate temperatures and consistent airflow across shelves.

• Meters airflow from the freezer to the refrigerator via a motor-driven damper door
• Helps the control system reach and maintain target temperatures
• Failure symptoms include: refrigerator too warm, items freezing near the vent, weak or no airflow from the diffuser, or repetitive clicking/ratcheting noises from the damper area
• A stuck-open or stuck-closed damper can cause temperature swings or ice buildup around the vent

• Disconnect power to the refrigerator before servicing
• Access the damper from inside the fresh food compartment; remove shelves and the cover/console as needed
• Unplug the wire harness and remove mounting screws; transfer any foam seals or ducts from the original to the new assembly if required
• Reassemble, restore power, and allow up to 24 hours for temperatures to stabilize
