The Freezer Door Gasket is an OEM component for Frigidaire side-by-side refrigerators. Situated within the gasket channel located on all four edges of the freezer door, this specialized rubber and foam insulation seals the door perimeter to maintain proper interior temperatures. Causes of failure involve degradation of sealing materials from repeated exposures to freezing conditions compromising insulation values over time. Symptoms requiring replacement include: Frost or condensation appearing around doorframe edges internally Rising energy bills from increased cold air leakage around doors Difficulties maintaining temperatures suitable for frozen foods Warping or shrinkage of gasket profiles eliminating tight contact Pro Tip: Soak the gasket in warm water and let dry prior to installation. This aids in letting the gasket take form and helps eliminate creases. This OEM Frigidaire part can also be used on Electrolux, Frigidaire, Gibson, Kelvinator, Westinghouse, and Sears/Kenmore.5304502761 (AP5986976) replaces 5304502840, 241778302, 4378488, 7241778302, PS11726449.
