The Door Gasket is an OEM replacement part for Whirlpool side-by-side refrigerators. This flexible rubber sealing strip is adhered around the entire perimeter of the refrigerated compartment door. The gasket creates an air-tight barrier, preventing cool air from leaking out when the door is closed.  Symptoms of a damaged door gasket include: Increased energy usage to maintain temperatures   Formation of frost or condensation around door edges Visible cracks or compressed areas impairing an air-tight seal Causes often involve general wear from repeated door openings and closing cycles. Exposure to heat and light can also compromise the integrity of the adhesive bonding of the gasket over time. This OEM Whirlpool replacement is compatible with Maytag, KitchenAid, and Jenn-Air refrigerators as well.2309216 (AP3884941) replaces 1175157, AH992921, EA992921, PS992921.
