I ordered a "genuine" GE replacement switch from AppliancePartsPros.com. I ordered the switch on a Sunday and received the part on Tuesday by FedEx. I had the switch replaced in about ten minutes and it solved the "no light" light issue.
Compared to other on-line appliance parts outlets, AppliancePartsPros.com had very competitive pricing. I chose them not only for being price competitive, but for the fact that they didn't gouge me on shipping charges. I didn't know the part would ship by FedEx, so that made my buying experience even better. This will be my souce for appliance parts from now on.
