I just bought a Harbor Breeze fan and am having trouble with the wiring. There are two bare copper wires, a white, and a black wire coming from the ceiling, and my fan has a black, blue, white, and two green wires. I have the blue and black from the fan attached to the black ceiling wires, the green wires hooked up to the two bare wires, and the white to white. Is there any reason this shouldn't work? Or am I just screwing up the directions!
