I have a vintage/antique tabletop fan. It is teal colored and the brand is "FRIGID". I think it might be from the 1950's or 1960's. It used to work great, and then today I went to turn it on and it wouldn't turn on at all. I started to try to take it apart, but I'm not sure what I should be looking for, or where to start. Any pointers or suggestions would be greatly appreciated.
