1 of the 3 bulb sockets in my ceiling fan stopped working. I replaced the bulb and it still doesn't work, so I'm assuming it's the socket that's bad? I don't use this light anymore and want to replace the entire fan/light with a standard light fixture, but I'm very interested in learning how to do it myself. Where would be the best place for me to start learning about how electric works and is there a certification available for home electrical work? I know I shouldn't tamper with something I don't understand so I won't, however, I very much want to learn. Any advice or direction is greatly appreciated. Thank you.
