The Fan Blade Grommet is an OEM replacement part for GE brand refrigerators. Located behind the evaporator fan blade where its central shaft passes through, this rubber sealing piece creates a protective barrier isolating the fan assembly. Causes of a potentially problematic fan blade grommet include cracks or deterioration that develop from continuous vibration and impacts over extended use. Exposure to temperature fluctuations can also cause the rubber to harden and lose elasticity.  Symptoms of a faulty fan blade grommet include: Airflow obstructions within the duct  Noisy vibrations from the fan assembly Rubber debris collecting on components This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore model refrigerators.WR2X7391 (AP2059311) replaces 297777, AH298476, EA298476, PS298476, SWR2X7391, WR02X7391.
