The LG 4987JJ1010M Refrigerator Door Gasket Assembly creates a consistent seal that limits air exchange between the cabinet and the door opening. This assembly is a sealing component that operates through an embedded magnetic strip, drawing the gasket into contact with the door frame when closed. Installed around the inner perimeter of the refrigerator door, it integrates with the liner and hinge alignment to maintain uniform contact pressure. As part of the cooling system, the gasket supports stable internal temperatures, reduces cold air loss, and improves overall efficiency. Replacing a damaged gasket helps maintain proper cooling operation and supports steady performance of the refrigerator during regular use.
