The General Electric WR78X20985 Refrigerator Freezer Bottom Drawer Gasket creates a consistent seal that limits air leakage and supports stable freezer temperatures. This gasket is a flexible sealing component designed to fit around the perimeter of the bottom freezer drawer. It works by using an embedded magnetic strip that maintains continuous contact with the drawer frame during opening and closing. Installed along the inner edge of the drawer, it integrates with the cabinet structure to control airflow within the freezer system. This part of the appliance improves temperature retention, reduces frost formation, and supports efficient operation of the cooling system during regular freezer use.
