Ceiling Fan Wiring  for Light and Fan Control Options
[ad#block]Ceiling Fan: I have a ceiling fan already installed in a house controlled by a single gang switch.
The fan contains two pull strings (fan on-off and light on-off). However the switch only turns light on-off.
I want to be able to switch blades on-off with the control of that switch as well.
Can I do this?

    I have a new home. The ceiling fan box has white, black, Red, & green wires.
    The switch is a single pole switch that has the red & black wires connected to each terminal of the switch, and the white wire is spliced off in the two gang box, and the green wire is grounded.
    I have tested the ceiling wires to find each wire to be hot simultaneously with the switch in either location. The black switch leg tests at 120 volts, the wire tests out 45 at volts. The switch tests out as being OK with the ohms reading.
    I feel this is reacting as if there is an open switch buried in the wall, or am I totally incorrect.
    The goal here was to install a Casablanca ceiling fan without a light operating on a mfg. matched speed control.
    Can you shed some light?

  2. Dave Rongey says:

    Hi Gary,
    The 45 volt reading is most likely due to a feedback which is typically caused by incorrect wiring connections. Please follow the resources in the article above to which will provide the switch wiring diagrams which will assist you.
    I hope this helps,
