I'm an amatuer do it yourselfer, and I had a 3 speed fan switch that wasn't working only got slow,slow, slow,and off. So I bought a new 3 way switch, wired everything according to the fan guide and how the last one was wired, now I have fast, fast, fast, & slow. No off. The switch is attached to a small black "transformer"?, could this be the problem? Any help would be great!!! Thanks.
