house has 2 black 2 white wires from ceiling. Remote receiver has 3 (bk/wh/green) wires to fan & ground. Remote receiver has 2 wires (bk/wh) that go to ceiling. Leaves me with 1 white 1 bk wire still hanging from ceiling and fan is not working. House built in 91.

The remote receiver has three that is good! You will need an inexpensive wire tester to wire this! or an electrician!

The two pairs of wires you have, two black and two white, are not normal either, for a house built in 1991. Should of had two sets of three! (Black/White/Ground) One pair of wires go to the switch. The other pair is your power source.



Normally ceiling fans or light fixtures only have the one set, because the power source is run to the switch box, then sent to the fixture via the switch being turned on. Yours has the source at the fixture and then run to the switch.



That is why the other answer said "that white wire is NOT a neutral" Because that pair of wires will carry the current both ways, black wire to the switch and white wire back to the fixture! So like he said mark it with a 'sharpie or black tape.



Purchase a current tester to determine which pair of wires are from the power source.



Always turn the power off when wiring something like this, but of course you will need the power on to find which pair of wires are from the power source, mark them and turn the power back off! Since the power source is in the ceiling, you will probably need to turn the breaker off to accomplish this! Switch won't do it!

Now for wiring it, Black power source to to Black to switch, White from switch to Black and Blue Ceiling fan, White Ceiling fan to White power source! Grounds to grounds, if any, or to fixture box!

Dollar to donuts you have the following:

One pair is incoming power, the other pair go to a wall switch and that is called a "reverse switch leg". If you don't want the wall switch to over ride the remote control just cap them off. Otherwise wire as follows:



In coming white splices to the white wire on the remote (next to the black) and both are labeled "line" or power in.

In coming black splices to the WHITE going to the switch and yes should be marked with a black stripe at both ends.

Black coming back is your "switch leg" and connects to the black on the remote (line).



Now to the remaining wires form the remote to your fan/light.



Black from the remote to the black from fan (operates the motor).

Red or blue from remote goes to the blue or other colored wire from the fan (operates the light).

White from the remote goes to the white from the fan.



Hint: take a sharpie and make up/down arrows (inside the battery compartment) that correspond to the direction of the little dip switches used to set the code the remote uses to communicate with the receiver. And of course you want to verify that both codes are the same. You laugh,but I've had more than one service call about a fan/light that stopped working after the 9v battery was replaced. The customer had bumped one of those little switches and changed the code.

Haven't done wiring for some years; but the 2005 code states that when a white wire is used to provide power, it must be use to supply the power TO the switch, NOT to the fixture. NEC 200.7(C)(2). If you are using a hand held remote, be sure the switch is kept in the ON position.

By 'remote' you mean the control switch?

That blk/wht pair that go from the switch to the ceiling are 'power in'

and 'controlled power to fan' out.

Green is always ground. If there's no ground wire, clip it to the metallic box.

One blk/wht pair in the ceiling is 'power' and 'neutral', the other pair is from the switch box,

and that wht is NOT a neutral. Mark it with a 'sharpie or tape.

CAREFULLY test for which one this is with power on.

Make damn sure no exposed wire ends are touching anything before you

switch on to do this.

Turn the power off, (test that it's off), and make your connections.

Ceiling: Power black to switch black, that marked wht 'return' to fan blk.

Neutral to fan wht.

Clip any fan ground Grn. to clg box.

Switch box.Blk in wht out. You're done.

Assuming you have no light kit, (no blue wire), just hook black to black, white to white, and green to green or bare copper.
