The location of fuses in a GE microwave oven differs from model to model, so a user needs a parts schematic for her specific microwave in order to locate the fuse or fuses in her machine. Parts schematics are available on the GE parts website, GEApplianceParts.com.
The model-number search tool on the parts website enables a user to quickly access the schematics for any GE microwave. As many as six illustrated schematics and accompanying parts lists are provided for each microwave, depending on the internal complexity of the model. The user should check each of the parts lists for fuses and then reference the schematic to identify the fuse locations. As of 2015, fuses can be purchased directly through the GE website.
