The Whirlpool WPW10436248 Refrigerator Door Gasket FIP ensures a proper seal to maintain stable internal cooling conditions. This gasket is a flexible sealing component fitted around the refrigerator door edge to prevent air leakage between the interior and external environment. It operates by compressing against the cabinet frame when the door is closed, forming a tight barrier that supports temperature regulation. Installed along the door perimeter using a press-fit or retaining groove, it aligns with the door liner for secure placement. By maintaining consistent sealing, this part assists in preserving cooling efficiency, supports proper airflow balance, and helps reduce strain on the refrigeration system during regular use.
