The Fuse is an OEM part for GE microwaves. It serves as a safety device designed to protect the microwave from excessive current that can cause overheating and potential fire hazards. When the current flowing through the microwave circuit exceeds a certain level, the fuse blows or breaks, cutting off the power to prevent damage or fire. Common causes for a fuse to blow include power surges, faulty wiring within the appliance, or the use of microwave inappropriate containers that cause sparks. It is essential to address these issues not only to replace the fuse but also to correct the underlying problems to prevent future failures. Symptoms of a bad fuse include: The microwave suddenly stops working. No signs of power or response even when the microwave door is closed and the start button is pressed. This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.WB27X10928 (AP3994062) replaces WB27X10388, 1262970, 875392, AH1481237, EA1481237, PS1481237, WB27X0713, WB27X10114, WB27X10247, WB27X10288, WB27X10474, WB27X1077, WB27X1159, WB27X713.
