Our ceiling fan switch clicks but the fan does not go on. When I opened the housing, I saw that there was 6 wires, 2 of which were white. One of the white wire was not connected, it could have caused the fan to stop working (?). I do not know where this white wire should be connected to as all the other wires are connected. Please help! Thanks. I do not know the model of the fan, only that it is about 20 years old.
