Description

This damper is the air-flow control assembly that regulates fresh air circulation in the appliance to help maintain consistent temperatures and compartment performance. Replaces a worn or stuck damper to restore proper airflow. What it does:
  • Opens and closes to direct fresh air between compartments or from the outside vent
  • Helps maintain even temperatures by regulating incoming air
  • Commonly linked to symptoms like uneven cooling, warm spots, or reduced airflow
  • Can fail by sticking, not opening fully, or making noise during operation
What's included:
  • One damper assembly
Install notes:
  • Disconnect power to the appliance before starting any repair
  • Handle the damper and actuator gently to avoid damaging plastic gears or mounting tabs
  • Verify orientation and secure mounting; ensure linkage or actuator is properly engaged
