How do I wire a replacement ceiling fan?
Look at the switches that control the fan/light... What color wires are connected to them? How was the previous fixture connected? Why didn't you simply connect the new device in the exact same manner?

If the fan and light used to be controlled independently by separate switches, I'd assume the previous wiring used the green wire as an ungrounded (hot) conductor. This would be confirmed by seeing the black wire connected to one of the switches, and the green connected to the other. This is an uncommon use of the green wire, and as you've found can be confusing.  If this is the case, you should mark the wire in some way to indicate that it is not a grounding conductor.

If you've confirmed that the green wire is indeed used as an ungrounded (hot) conductor, then the wiring will be as follows.


Black from ceiling to black from fixture.
White from ceiling to white from fixture.
Bare copper from the ceiling to green/yellow from fixture.
Green from ceiling to blue from fixture.


If the green wire is not used as an ungrounded (hot) conductor, contact a local licensed Electrician and have them install the fixture.
