Customer Questions and Answers for Air Tower (Refrigerator Air Duct) by Whirlpool

This air tower is the vertical duct that channels cold air from the evaporator through the cabinet vents to distribute cooling across shelves. Replacing a cracked or blocked tower restores proper airflow and more consistent temperatures.

• Directs and distributes cold air from the evaporator to the fresh food area
• Helps maintain even temperatures and airflow across the compartment
• Common symptoms of failure: weak/no airflow from vents, warm spots, frost/ice around vent area
• Physical damage such as cracks, broken tabs, or warping can allow leaks and reduce cooling

• Disconnect power before servicing; wear cut-resistant gloves
• Remove shelves/drawers and the rear interior panel to access the tower
• Transfer and reuse existing screws/clips; align tower to seal against vent openings
• After installation, restore power and verify unobstructed airflow from vents
