The Refrigerator Gasket is an OEM replacement part for Frigidaire models. It provides a sealing barrier around the door frame, preserving cool air inside the refrigerator compartment. Composed of durable synthetic materials, the contoured gasket creates an insulating shield. Causes of a faulty gasket include cracks or breaks from over-closure of the refrigerator door. Deterioration from extended exposure to temperature extremes can also impact integrity over time. Symptoms of a bad refrigerator gasket include:  Inability to maintain a consistent internal cooling temperature Accumulation of moisture or frost at door edges   Visible gaps allowing warm external air to infiltrate Air leaks around the refrigerator opening Compatible models include brands produced by Electrolux, Gibson, and Kelvinator.This part fixes the following symptomsDoor sweatingFridge too warm218730603 (AP2115004) replaces 218730604, 08009733, 215732402, 215732412, 215732462, 3001517, 3017373, 3200261, 5303001517, 5303017373, 5303288857, 5318680311, 53339, 751, 8009733, 86609, FR107, G175324-11, G180547-11, G186803-11, G186932-11, PS428566, R000901154, SWC28, SWC41.
