Wiring a Ceiling Fan

Electrical Question: I am trying to install a ceiling fan. The fan itself has a white, black, blue and green wires.

  • The supply circuit has a black, red, white, and copper wires.
  • I color coded them, but I am left with the blue wire from the fan and the copper and red wire from the supply circuit.
  • According to the instruction stated to connect the ground conductor of the 120v supply (this may be a bare or a wire with green colored insulation to the green ground lead(s) of the fan.
  • I only have the red and the copper wires left on the supply circuit.
  • Am I correct to connect the blue wire to the copper wire.

Your assistance is greatly appreciated.

How to Connect the Black White Red and Green Wires of a Ceiling Fan

  • The Red wire from the junction box connects to the Blue wire on the Ceiling Fan.
  • The Bare Copper wire from the junction box connects to the Green wires on the Ceiling Fan.
  • NOTE: Because your junction box wiring has a separate Black and Red wire, this normally indicates that there are two separate wall switches, one for the Fan Motor (Black) and one switch for the Ceiling Fan Light Fixture (Red).

    I am changing ceilings fans. The original was a fan with lights and I have separate wall switches for fan and light. I am replacing it with a fan that also has a light. We are just makinga “style” change. In the ceiling are 2 sets wires- One has 3 wires; black, white and bare. The other has 4 wires; black, white, red and bare. There is a green ground wire on the ceiling fan mount plate. Now, coming out of the fan are 3 wires and the green ground. The wires are black, black/white and white. The instructions are woefully scant and do not account to the 6 wires from the ceiling. Please tell me how these should be connected inorder to preserve the dual switch option.

    I have a new home which has a switch that turns power on to a socket. I am installing a new ceiling fan. (it is not prewired). I want to tie into the existing switch that ties into the existing outlet so the switch controls the fan and outlet. Is this OK and whats the best practice

    I am replacing a broken ceiling fan in my family room. I have 3 wall switches for the fan light and 1 for the fan itself. I also am installing a remote control as the ceiling is 18 ft high. I have a black, red and white wire from the ceiling. The remote control device only has a black and white going to the power. How do I wire this?

      Hi Jim,
      Please follow the links to the Ceiling Fan section which fully explains the process of How to Wire a Ceiling Fan Remote Control switch.

      • sam says:

        The guest is talking about how the remote control receiver only has a white and a black input while the ceiling has black red and white output. Your indicated tutorial doesn’t talk about how to wire this case. Where do the ceiling red and ceiling black wires go into the remote receiver if the receiver only has input white and input black.

        • Dave Rongey says:

          Hi Sam,
          The ceiling wires will need to be positively identified to know their functions and how the circuit wiring is controlled. In some installations where there is one 3-wire cable in the ceiling box with a red, black and white wire there may also be two wall switches present, typically one switch for the ceiling fan motor, and one switch for the ceiling fan light. In this example the black wire from the ceiling box is generally attached to the black wire of the remote module, and the white wire of the ceiling box attaches to the white wire of the module.
          I hope this helps,

  5. sarah says:

    I have a ceiling fan that has wire spots marked A N E & LA but no wires coming from them. The wires coming from my ceiling are red black white and green. Which wire goes into which labelled space in the fan? This is a fan with a light that has no control except for the wall switch which has an on off switch for the light and a dial (3 speeds and of) for the fan. How do I wire this so it will work correctly?

  6. Robbie Williams says:

    I am trying to hook up a ceiling fan. It has blue, black, white and green wire the wires in the house are red, black, white and green. Do I hook the blue to the red?

    • Dave Rongey says:

      Hi Robbie,
      In most installations like you have described, the red wire is connected to the blue wire if there is a separate wall switch which controls the light of the ceiling fan, and the red wire is connected to the wall switch. This is best discovered using a voltage tester and flip the switch on and off.
      I hope this helps,
