how do you connect a ceiling fan up to your excisiting light fixture that has only three wires?

Question

ceiling fan has a green wire a blue wire a white and a black wire ceiling fixture only has three black wires How do I conect them togeather?

Answer 1

You start by figuring out what the three black wires are connected to and possibly replace them.
If you will be controlling the fan and light from the pull chains, then you need to connect the blue and black wires together to a black hot wire. The white connects to a white neutral and the green to safety ground green or bare copper.
If you want to control the light and fan separately from a wall switch, then you need to buy 3 conductor plus ground and run it from a box with separate switches (or speed/dim controls). The white and green are still the same, but the 3 conductor will also have black and (usually) red. Connect the black to black at the fan and the red to blue. Almost always, black is the fan, but check it before you button everything up. At the box, you will have a hot and neutral coming in (with ground) and the hot black will connect to the common on the switches/controls and the 3 conductor will have red to the light and black to the fan switch//controls. White to white and green/copper to green/copper.

Answer 2

First you need a Wiggins or electrical voltage checker to help you find the hot line the neutral line and the ground two of witch are supposed to be grounds. If you have two hot lines at the lite box you should have a double switch on the wall .
one for fan and one for lite but if you don't then most likely the third wire is a second ground or pass thru to another lite fixture. If not go ahead and hook the red and blue together to the hot wire and white to the ground and green to the other third wire that is if it is a second ground now you have voltage from the switch to the fan and lite and you will have to control by the switch's on the fan. SAVVVY? After you have hooked this up and if for some reason one or more of recepticles or switchs dont work it is most likely that the third wire is supposed to be hooked up in conjunction with the ground as a pass through.

Answer 3

you first must find out which is the hot wire you will need a tester for this,than find the neutral which should be white, but according to this wiring it was not done according to code the green wire is the ground wire,the hot wire from your ceiling goes to black wire in your fan,the blue wires are also wired to hot wire in ceiling they go to the lights in fan,the white wire goes to neutral wire in ceiling and the green goes to ground or bare wire in ceiling .

Answer 4

Black/Blue to the Blacks. White to White, Ground to Ground

Answer 5

find out which is the power by using a tester

Answer 6

go to home depot and buy a special dimmer/ toggle switch made just for that.
