The Door Gasket is an OEM part for Whirlpool refrigerators. This gasket forms an important seal around the refrigerator door, preventing warm air from entering the sealed interior compartment. Maintaining proper temperature and humidity levels inside depends on an intact, well-sealed door gasket. Causes of a bad door gasket can include cracks, tears or deterioration over time due to exposure and normal compression/expansion cycles. Food particles or debris trapped against the gasket can also damage sealing integrity. Symptoms of a bad door gasket include: Difficulty closing or sealing the door properly Higher electric bills from the refrigerator running more often Warm air leaking into the refrigerator sections Loss of interior temperature regulation This genuine Whirlpool OEM replacement part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.2177311 (AP2980864) replaces 2171392, 2202882, 449110, AH326951, EA326951, PS326951.
