I have a single 14/2 supply line going into a switch box with two single pole switches. From there, two 14/2 lines go to a ceiling junction box with a fan that has a blue, black, and white wire. This fan also has a remote control. I'd like to have one switch control the fan blades and another control the fan lights. I can't find a diagram for it but the one I posted is basically what I am working with except the Power Supply is not at the fan, its at the switch box so I can't actually use this diagram:

enter image description here

I imagine I could use the black wire from one of the 14/2 lines to power the fan, and the black wire from the other 14/2 line to power the light, and not use the second line's white wire. In effect making this more like a 14/3 to the ceiling junction. I doubt that is safe or code (correct if wrong).

Rewiring isn't really an option so if I can't setup the switched fan and switched light separately, it looks like I could just disuse one of the 14/2 lines and use a single switch....but that would be fan + light on/off and having to use the remote, which isn't ideal.

Any options here? Maybe a special kind of switch or something else I'm nothing thinking of?

There is also a second downstream junction box with another fan if that's relevant but it inherits the wiring from the first junction box.

    You say the diagram you posted an image of isn't correct, but you don't tell us what the correct diagram is. Are the wires from the two switches really two independent sets of wires? Only one of which has the power coming into it? I doubt it, but you haven't told us what it actually is. Find or make a picture of how the wiring goes.

  • I'm presuming one fixture neutral in my answer, since that's what's shown in the diagram.

  • Is getting some sort of smart-switch or fan-speed controller in not an option either? Commented Mar 25 at 2:16
  • Its all about the neutral and if you have 3 or 4 wires from the switch to the fan. Commented Apr 24 at 20:00

(Please pardon the wiggly lines. Trackballs are wonderful for many things, but drawing smoothly is not one of them.)

If you can pull new wiring, the obvious solution would be using four-conductor (including ground) cable rather than three-conductor: Two switches, one hot/alternate-hot/neutral/ground output cable, explicitly grounded switches

... I'm not sure how else one could solve it, other than using pullchain switches in the fixture or a remote of some flavor.

    The first wiring arrangement's a Code vio -- 300.3(B)/310.10(H) prohibit parallel neutrals like that, and you can't simply abandon one of the neutral wires either as then you'd have issues with current not returning on the same cable it came in on Commented Mar 25 at 2:16
  • Zapped, then. Better solutions welcome...

  • The model of fan is Aerodyne with LED 52inch: hunterfan.com/products/…

    If it didn't work, I'm not sure I buy your assertion that it was wired that way.

    @Jimmy, Instead of having everyone guess how the fan is currently wired, post a pic or a diagram of what is there now.

Option 1 If you can separate the neutrals in the fixture, and connect one of the 14/2 neutrals only to the fan's neutral, and the other only to the lighting neutral, you'll be all set. This may be easy, it may be impossible. You will not be able to control fan speed this way so it's not your first choice, IMO.

Option 2 You can put the entire fixture on one switch, and use the pull chains to control everything.

Option 3 You can install a wireless remote fan controller in the ceiling canopy. Feed it from just one switch, that will act as a "master switch" and usually be left on. Control the light and fan with the battery-powered remote control that comes with the controller.

As noted in your question and comments, you must not use 3 wires from two 14/2 cables as if they were a 14/3 cable.
