The Whirlpool WPW10238068 Refrigerator Gasket Black is a replacement door seal used to maintain proper internal conditions by preventing air leaks. This gasket is fitted along the edge of the refrigerator door, where it forms a tight seal against the cabinet when closed. It operates through a flexible magnetic strip embedded within the gasket, which connects securely to the frame to regulate internal temperature and limit external air entry. Installed around the door perimeter, it is used in refrigeration systems to support consistent cooling performance. By assisting in sealing efficiency, this part helps reduce temperature fluctuations, supports proper cooling conditions, and lowers unnecessary energy use during regular operation.
