The black door gasket, specifically compatible with brands such as Hotpoint, General Electric, and Sears-Kenmore, serves as a sealing component for refrigerators and freezers. Identified by part number WR24X10079, this gasket is essential for maintaining the integrity of the refrigerator's seal, effectively keeping warm air out of the freezer section. To smooth any wrinkles, immerse the gasket in warm water or gently apply a hair dryer on a low setting. During the installation process, ensure that all perishable items are safely stored to avoid spoilage.
