I know this is a common topic and I read a few threads but would
appreciate any help.
My guest room is pre-wired for ceiling fan. There are 2 switches (one
for fan and one for light).
The junction box has 4 wires in it. Black, White, Red and Bare
I bought a fan with a separate remote control. After I connected the
remote to the fan control, I have a black and a white wire coming out
of the remote control and a green from the fan (for the ground).
My question is which of the wires in the junction box should I use. I
guess the Black is hot wire for the fan, so that is easy to connect it
to the black on the junction. Should the white be connected to the
white on the junction or the red wire.
Your response is appreciated.
I would think that the red would be the Hot for Light.
Typically when you run a circuit to a device that needs 2 hots, you run a
14/3 or 12/3 Which is a Hot Black, Hot Red, Neutral White, and Copper
Ground. The voltage for both hots will travel back through the 1 Neutral.
You should also have in the Junction box a Black, White and Ground feed from
the power source as well as the Red, Black, White, Ground.
If All that you have in the Junction is Red, Black, White, Ground, then you
Have some Figuring out to do. That would mean that the power feed is at the
Fan and they are bringing the Power via 14/3 or 12/3 to the Junction and
using one wire for the Power In and the other 2 for the Power Out to the
I'm not sure if there is a standard color Scheme for that. You might have to
look at the Junction Box under the Fan to see where the wires are fed from.
You might be able to use the Ground as a Point of Reference and use a Meter
to figure out which is the Hot Leg of the three. Then trial and Error for
the Light/Fan Legs.
The white is neutral or common.
Red and Black are your two hot wires, one for the fan and one for the
So all your white wires should connect together. The black should
go to black and the Red should go to either a 2nd black wire or to the
red blue or whatever wire the instructions say is hot.
