The Grease Filter is an OEM part for GE range hoods and microwaves. It captures grease and other airborne particles generated during cooking, preventing them from accumulating in the appliance and ductwork. This filter helps maintain the efficiency of the exhaust system and reduces the risk of grease fires. Over time, the filter can become saturated with grease and other residues, reducing its effectiveness and potentially causing odors or airflow issues. Symptoms of a bad grease filter include: Reduced airflow or ventilation performance Persistent cooking odors Visible grease buildup on the filter The filter appearing damaged or worn This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.WB06X10608 (AP3883312) replaces 1166430, AH1022452, EA1022452, PS1022452, SE-2800-006, WB02X28930.
