Diffuser (Refrigerator Air Damper)
Genuine Whirlpool part
By: Whirlpool
Part Number: W10899382

This diffuser—often called the refrigerator air damper—controls how much cold air flows from the freezer into the fresh food compartment. Replacing a worn diffuser helps restore even cooling and more stable temperatures throughout the refrigerator. What it does:

  • Opens and closes to regulate airflow from the freezer to the refrigerator
  • Helps maintain set temperatures and reduce warm spots or over-cooling
  • Common symptoms: fresh food too warm while freezer is OK, food freezing on shelves, weak airflow from upper vents, or clicking/buzzing from the diffuser area
  • Helps address frost or condensation near the diffuser outlet
What's included:
  • 1 diffuser
Install notes:
  • Disconnect power before servicing
  • Access from the refrigerator section; remove shelves/air duct covers as needed
  • Note wiring and orientation; remove mounting screws/clips and transfer any seals/insulation if present
  • After installation, restore power and allow up to 24 hours for temperatures to stabilize
