    Default Controlling Ceiling Fan from Wall Switch

    I just replaced a ceiling light, which could be operated from a wall switch, with a ceiling fan/light.

    When I disconnected the ceiling light, I unhooked white from white and black from black. A red source wire was capped with a wire nut.

    I wired the ceiling fan/light -- black/blue(for the light) to black, white to white, and left the red source wire capped.

    The only way I can turn the fan and light off and on is with chain switches, not the wall switch.

    I did the same thing with another ceiling fan/light with no problem -- I kept wall switch control.

    Thanks for the help.

    I would say double check your wiring. It sounds like you connected to a constant hot and not the switch leg. Do you have access to a voltage tester? If not, keep the white wires connected as is and connect the others to the red.

    Before you start swaping wires around, what all wires are in the box and what all wires do you have on the fan?

    By the way, check your switch to see how it is wired.

    Thanks for your reply. Sorry for the delay in getting back to you.

    In the box there is white, black and red.

    On the fan there is white, blue, and black. (Fan black is connected to box black to provide power to the fan, and fan blue is connected to box black to provide power to the fan light.)

    P.S. I just checked the wall switch. Black and red are attached to the switch.

    I suggest you first look to see at the wall switch. See if there is a red wire connected to the switch. Use a electrical tester and see when you turn the switch on the red wire becomes energized. Then take the tester to the ceiling red wire and see if it is energized when you turn the switch on. If it does then the red wire in the ceiling box is the wire that you need to hook the light part of your fan to. That typically is the blue wire. Then connect the black wire on the fan to the black in the ceiling fan black. The white wire will still be connected the the white wire in the ceiling box. Now when you enter the room and turn the switch on. The light part of the fan only will light. The fan will not be operated from the switch on the wall. But it can be controlled by the chain switch on the fan. This allows you to turn the fan on while sleeping with the light off. I hope that helps.

    What Raven suggested.............


    That red capped wire in the ceiling box and not being used just don't sound right.

    It sounds like you are missing a couple of wires, are you sure there isn't another set of wires in the box? I'm going to quess that what you have is more like this

    This will allow the fan to work on the chain, and the switch to operate the light.

    Thanks for the diagram; how did you do it?

    There's only the one set of wires in the box - red, black, white.

    Do you think the switch was wired by the developer for an overhead fan/light, i.e., the red from the wall switch connects to the blue from the fan light, so the light can be controlled from the wall switch, and the black from the wall switch -- probably always "hot," connects to the black from the fan, so the fan gets controlled by it's pull chain?

    Another forum member suggested this hookup.

    Thanks,
    Bob

    I think you may be right. The developer must have prewired the wall switch this way to support a ceiling fan/light. I had the developer install a ceiling light, before we moved in, which explains the cap on the red wire in the box.

    Thanks,
    Bob
