Wiring for ceiling fan question.

ingeborgdot

I am going to put up a ceiling fan and have a little wiring question. The ceiling fan has a black and white. The junction for the ceiling fan has (1 black,) (2 white), and (2 black and 1 white). Which is which? Not sure how they did this but I would like a little advice. Where should my white from fan go? black from fan? Thanks.

Do It Right

The splice with 2 black and 1 white is constant power (white feeds the switch).
Tie the fan black to the 1 black, tie the fan white to the 2 whites.

Ok, that's what I will do? What does a person use the other constant power for?

The problem that I now have with only a two wire fan is that when I turn off my light the fan turns of also. It is also a insteon dimmer switch that runs to it, so when I start it up it has a slow start and it can't dim my lights unless it gives less power to the fan. I had it hooked to another fan with no problem before but this one has only two wires and now with black to black and white to white like that it does not work the way I want it. I was not aware that it was only a two wire fan. Any ideas on what to do?

Is this a fan that comes with a remote control? Those models generally only have two wires.

Yes, I had never had one with a remote and thought it may be cool but it is causing a lot of problems. It also is a very loud fan. Motor noise. Some other things are not right with it so I am taking it back.

If you only have one switch on the wall, and only a black and white wire at the box, then you can only power the whole fan and light from there, you cannot dim the light without dimming the fan.

If you keep with a fan with a remote, you can just use the remote to dim the light seperatly, leaving the fan on full power. Otherwise, you will need to replace the 2 wire cable with 3 wire cable, allowing you to have control over the fan and light seperatly.

Put some pictures up of the box, the switch, and the new fan and we can help more.

The fan wire can be splice to the pair with the black/white pair and will be hot all the time. You would need to use the pull chain.

The light kit wire can be spliced to the lone black and will be operated by the wall switch.

The other fan would not work the way I needed it to because it was only a two wire fan that also controlled the light. I could not get around my dimmer switch in my system. I had to change the fan and light. I now have a three wire fan. White, black, blue. How can I make it to where the fan is not controlled by the switch? I want it always on so I can control it from the pull chain. I have (1 black,) (2 white), and (2 black and 1 white) coming into the box. The white should go to white, the blue for the light to the black, but should the black for the fan to stay on all the time go to the 2 black and one white to stay on all the time?

Yes. Just like Jim Port said.
