have have an old fan no diagram available to help wire it up. The
ceiling box has 2 sets black and white wires coming into it, run by a
dimmer switch on the wall. The fan has a light and has a black, white
and green wire coming from it. I would like to wire it so that the light
is controlled by the dimmer switch and the fan is controlled by the
fan's pull chain. Any help greatly appreciated.
Trying to figure out why you have 2 blacks and 2 whites in the
ceiling box...a few questions for you -
Was anything previously wired into this box? and did it work?
If "yes" to above, any chance there is another (or multiple)
fixtures in the room controlled by the same dimmer?
Any chance either of the two white wires has a piece of black
electrical tape wrapped around it?
no this light is the end of the line. Originally there was a chandelier
type light controlled by a throw switch. I added the dimmer and this old
cieling fan when I moved in. There were always 2 lines into the box and
yes they were both hooked up and yes the fan and the dimmer both worked
correctly. I removed the old fan to put up another chandelier type and
didn't pay attention to the wiring, the wife didn't like the chandelier
so I have to reinstall the the old fan again.

Your ceiling box has a switched circuit and an always-on circuit (right?),
but the wires leading into the fan unit are a single pair (black and white)
which are internally switched (by pullchains) to control the fan and light.
Therefore, you cannot control the fan and light externally and
independently. You could buy a new fan unit, one that has a black, white,
and probably a blue wire coming out.
Chances are very good that the "black and blue" wires are
wire-nutted together inside the fan switch housing. I've put
a dozen light kits on ceiling fans, and the manufacturers give
the consumer instructions on how to do it that way, in most
This is incorrect. The power feed cable black wire is connected to the
(hot) wire coming out of the fan (that is connected to the fan) _and_ to the
switch leg cable white wire. That switch leg cable white wire should be
marked with black tape in the ceiling box and also in the switch (dimmer)
box. The white wire coming out of the fan is then connected to power feed
cable white wire. The black wire from the switch leg cable then connects to
the (needs to be pulled in) wire coming out of the fan (that is connected to
the light). The fan will then be controlled by the pull chain and the light
controlled by the dimmer switch.
Pulling in the extra wire for the light is correct and necessary.......but
if the white wires are all connected together in the ceiling box as you
mentioned above, connecting the (pulled in) light fixture wire to that
"dimmer" black wire will do nothing whatsoever to turn on the light.
Go back and read what he wrote: 1 "set" of black/white is
controlled by the dimmer, the other set is always hot.
I also ASKED HIM about one of the wires being taped to indicate
black, he said onthing of this.
if you're going to (wrongly) nitpick what I say, at least do
it honestly, don't take words out of people's mouths and ignore
what they're giving me as facts.

Go back and read your own post, the way you told him to connect the light
".....all 3 neutral/white wires get tied
together with a wire nut." will _not_ work. In this case, just because the
white wire isn't marked with black tape doesn't mean that it isn't being
used to feed the switch......as was common practice years ago (and permitted
by NEC back then). The correct method back then was that it was required to
feed the switch with the white wire and the black wire was required to be
the return wire to the light (switch leg). The requirement to mark the
white wire with black tape is only a recent NEC change, thus it is not
uncommon to see unmarked white wires being used to power up switches in
older houses (pre-1996, IIRC).
Nitpick? The light will _never_ work if he connects it the way you told him
to do it. Are these _not_ your words from an earlier post?: "OK, the black
white and green coming from the fan/light --
1st things first: the green attaches to a ground screw in the
ceiling box, hopefully along with ground wires from the other
two cables coming into the box. You don't mention them, but
they should be there. 2nd: All 3 neutral/white wires get tied
together with a wire nut. You might want to label your switched
and "constant" black leads to avoid confusion."
"All 3 neutral/white wires get tied togehter with a wire nut"......wrong.
Bad dog! NO bone!

When talking to Tommy Boy , you have to remember one thing. Tommy thinks
the NEC code stands for Non Electrically Concerned code. You only follow it
if you want to , and if you are called a Lesstrican. If you are call a
Electrician you have to follow the the real NEC code. There is a big
difference here and you need to know the difference to be able to talk to
tommy. There is a big difference between the Lesstrican and the Electrican
OK... heres what I did to get it to work... took constant black and
switchline black to fanlight black, switchline white to fangreen (light)
and fanwhite to constant white. If anyone sees a problem here please let
me know! thanks again.

Tommy, get those small hands out of the electrical box and put them back

You have proven time and time again that you don't have a clue about
electrical practices, nor do you understand anything about the letters
Your advice is dangerous, wrong-headed, and just plain harmful.
