Kitchenaid Refrigerator KSRU25FKWH02 Fridge too cold

The air diffuser is the damper assembly that meters cold air from the freezer into the fresh food compartment. Replacing a sticking or broken diffuser restores proper airflow and helps keep refrigerator temperatures balanced and consistent.

• Regulates and directs airflow from the freezer to the refrigerator compartment
• Opens and closes to balance temperatures between sections
• Helps prevent warm spots or freezing near vents in the fresh food area
• Typical symptoms: refrigerator too warm, items freezing near vents, continuous or no airflow through the diffuser, or frost buildup around the diffuser opening

• Disconnect power before servicing
• Access from the fresh food section; remove shelves and the diffuser cover/grille to reach the assembly
• Transfer any reusable mounting hardware or seals from the original part
• Restore power and allow up to 24 hours for temperatures to stabilize; verify airflow through the diffuser
