The Capacitor is an OEM part for GE microwaves. This component stores and releases electrical energy to help power the microwave's high-voltage circuits, essential for the proper functioning of the appliance. Over time, capacitors can fail due to electrical surges, overheating, or degradation of the internal components. When a capacitor goes bad, it can affect the microwave's ability to generate heat and operate efficiently. Symptoms of a bad Capacitor include: The microwave not heating food Unusual humming or buzzing noises The microwave shutting down or not starting This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.WB27X10011 (AP2025931) replaces 254536, AH239120, EA239120, PS239120, WB27X0585, WB27X585.
