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:
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.
A1:
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.
