wiring with red wire

I am installing a cieling fan ....the fixture has only white and black wire. My electrical box has white black and red wire for the wall switch. Do I wire the red wire with the black or white wire? Thanx.

 

Open the box with the switch, describe the wires you see and how they are connected.

Most likely you will see an unused red wire in the switch box, with the black wire from the same cable connected to the switch. The red wire is in case you want to add a second switch to control a light kit for your fan. In this case at the fan connect black to black and white to white. Leave the red unconnected. (You must not have a light kit on the fan or you would have another wire coming out of it.)

There are other ways your wiring may be configured. Post back with more information if your configuration is different.

 

Your old fixture had a separate switch for light and fan, and I bet you have a dimmer with separate light & fan controls on your wall.
Since you don't need that extra circuit anymore, do the following:

- If you don't intend to use a fan switch(in which I find no reason to), open the wall switch, disconnect that red wire from the dimmer, cap it at both ends and forget about it. Connect white, black and bare copper as instructed.

You don't have to pull out that red wire as long as you terminate the ends well; it'll be there and available when times comes to replace your current fixture to a new one that has a separate light/fan circuit.
