The Door Gasket is an OEM replacement part for Whirlpool refrigerators. It forms a seal around the refrigerator door to maintain proper interior temperatures and energy efficiency. The gasket is a soft yet durable material designed to compress tightly against the door frame. This creates an air and heat tight barrier preventing warm outside air from entering the refrigerator compartment. It also helps cold air from escaping. Causes of failure are usually due to compression fatigue through years of repeated door openings and closings. Exposure to excess moisture can degrade the material over time. Symptoms of a bad door gasket include: Inability to properly chill or cool foods inside the fridge Higher than normal energy consumption Visible cold air leaks around the door frame Door not sitting flush causing difficulty closing fully This is a genuine Whirlpool OEM replacement this part is also compatible with Maytag, Jenn-Air and some Kenmore models.W10830287 (AP6262414) replaces W10443259, 4841406, PS12173626, W10218678.
