The Gasket is an OEM part for Frigidaire refrigerators. This door gasket is crucial for creating an airtight seal around the door, ensuring that the cold air stays inside the refrigerator to maintain optimal food preservation conditions. The gasket helps to prevent warm air from entering, which can lead to frost buildup and increased energy consumption as the refrigerator works harder to keep its contents cool. The primary cause of gasket wear and tear is frequent use, which can stretch or damage the seal over time. Other factors include aging of the rubber material, which can lose its elasticity, and improper cleaning methods that can degrade the gasket's integrity. Symptoms of a faulty Gasket include: Noticeable gaps or tears in the gasket, which can lead to cold air escaping. The refrigerator runs more frequently or for longer periods, indicating it's struggling to maintain the desired temperature.
