Hello, I was recently trouble shooting and with some research I learned that my 'Hampton Bay Roanoke' natural iron ceiling fan, may have built in or compatible light dimmer. I was wonder if I really do have this option and how can take advantage of it? If not, which dimmers is this compatible with?

If you have pull chains, could add most Remotes and receivers.
If it has no pull chains, you will need the remote for that unit. Usually in the canopy.
