Possible Causes

Stuck air damper, Broken damper motor, Blocked air channels by ice, Mispositioned food blocking vents

How to Fix / Troubleshooting

Safety first: Disconnect power before removing internal covers.

  • Check air vents: Locate the cold air vents between freezer and fridge compartments. Ensure they are not blocked by food packages or containers.
  • Listen for damper movement: When the fridge door is opened and closed, you may hear a faint opening/closing sound from the damper area. Absence of sound can indicate a stuck damper.
  • Inspect for ice blockage: Remove shelves near the vent area. If you see frost or ice around the vent, unplug the fridge and allow it to defrost for 12–24 hours with doors open, placing towels to catch water.
  • Access the damper (if serviceable): On some models, the damper is behind a plastic cover in the fridge section. Remove screws/clips and gently pull the cover to inspect the damper door.
  • Check damper door movement: Manually move the damper door if accessible. If it is jammed or broken, the damper assembly should be replaced.
  • Reassemble and test: After defrosting and ensuring vents are clear, restore power and monitor temperatures over 24 hours.
  • If issue persists: A failed damper motor or control board may be at fault and typically requires part replacement by a technician.
