I am installing a Hampton Bay Ceiling Fan with light kit. When I removed the old fixture, I noticed I had the green ground wire, the white neutral wire, and a red and black wire. The Red wire was used on the old fixture, and the black wire was capped. When attacing the new fixture I used the red wire as the hot wire and the unit is not working. Should I try the black wire? I am open to suggestions. Thanks for everyone's help with this, It is HOT in NJ. I need the fan NOW! LOL
