Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Refrigerator section too warm
• Refrigerator section too cold or food freezing
• Little or no cold air entering the refrigerator compartment
• Clicking or repeated motor noise during damper operation
• Frost or ice accumulation around the diffuser opening

Check Before Replacing

• With the refrigerator connected to power and the freezer door closed, verify whether cold air is entering through the diffuser vent in the fresh-food compartment; lack of airflow can indicate a closed or nonoperating damper, but does not by itself confirm part failure.
• Observe or listen for damper-motor operation during a normal cooling or temperature-control cycle. No activation or repeated clicking can indicate a diffuser problem, but wiring and control components should also be considered.
• Disconnect electrical power before accessing the assembly. Inspect the damper opening for frost, ice, or a visibly damaged door/linkage without forcing the door.
• If frost is present, safely check for possible air leaks at the refrigerator door seals and ice-dispenser flap before condemning the diffuser.
