The LG Refrigerator Multi Air Duct Assembly (Part Number / SKU: ADJ74712202) is an authentic OEM replacement air channel housing designed for compatible LG refrigerator models. Mounted along the interior back wall of the refrigerator or freezer compartment, the multi-flow duct features a series of precisely engineered louvers and internal channels that distribute the cold air blown from the evaporator fan evenly across all storage shelves and door bins. Over time, physical impacts from loading groceries, plastic brittleness from prolonged sub-zero temperatures, or broken mounting clips can damage the duct housing or louvers. When an air duct cracks or becomes misaligned, airflow gets choked or misdirected, resulting in uneven cooling, warm spots on certain shelves, or frost accumulation around the vents. This genuine OEM replacement restores proper multi-flow air circulation and precise temperature zoning.
Key Features
OEM Multi-Flow Air Shroud: Factory-designed louver layout engineered to deliver balanced, multi-directional airflow across all internal food storage zones.
Insulated Thermoplastic Construction: High-grade polymer material resists warping, cracking, or thermal degradation under continuous freezing and humid conditions.
Integrated Vent Louvers: Precision-molded openings ensure optimal air velocity and prevent pressure drops within the cooling loop.
Benefits
Solves common refrigeration issues such as warm spots on specific shelves, uneven cooling performance, broken or rattling vent covers, and obstructed airflow.
Restores factory-grade refrigeration efficiency and consistent food preservation standards.
Direct OEM replacement ensures exact screw hole alignment, harness routing channels, and snap-in clip placement without modification.
Applications
Designed for compatible LG refrigerator models requiring multi air duct assembly part number ADJ74712202.
