Wiring A Fan


I took my old fan down last summer, and for the life of me, I can't remember which wire went to what. I've attached some pics of what I'm working with and the wires of the new fan. Looking for what wires should be connected together. The sticker on the blue wire says "For Light Connection"

Most likely one set of wires is the power feed,
The other set is the switch loop.
Have you got a tester ?
Test across the two black wires,
Thats the most likely one.

For the fan,
use the white and black wires.
dont forget to ground the green wire.

I put a tester on it and couldn't get anything to register. Since the white wires are together already, would it matter which wire off the fan connected to either black? What about the blue wire?

Yes it matters.you have to determine which black is hot. Test again with power on and switch on.
The blue wire also gos to the hot to power the light on the fan.
You should also remove that tape from the whites and put a nut on them.

The blue wire is for an optional light on the fan.
Does yours have one ?
If not leave it.
Test for any voltage between the white wires,
and the black wires.
One black should be hot (supply in ).
If neither one is hot, you have no supply !
If all is well, and the switch is in the on position,
then both blacks should be hot !
with respect to the whites.
If the second black is not hot,
this indicates a fault in your switch loop.

And yes, cap the whites when finished.

I'd like to revisit this again....yeah I know, its been almost two months. BUT, I have more information.

With the switch off, one black wire is hot, and the other isn't. Same way with the switch on.

I took everything down on a fan in another bedroom to see how it was wired. It has a similar setup, two black wires coming from the junction box, with both white wires tied together. One white wire from the fan tied to one black wire from the ceiling. One black, and one black/white hooked to the other black wire from the ceiling.

I am assuming I will have a similar setup with this once I can figure out which wires from the fan hook to what wire from the ceiling. Yes, the new fan has a light, and yes, the white wires now have a nut on them.

Test the two black wires,
One should be hot with switch in ON position !
It should be dead with switch in OFF position,
Use this wire as your HOT.
The other black is your neutral.

What do you want to do with the light in your new fan,
as you have no switch line.

The one that is hot is so with the switch on and off. The other is dead with the switch on and off. It's almost like they took the hot wire to the junction box in the ceiling instead of the switch, and once you have something "bridged" between the two black wires in the ceiling, it may work. I don't know.

And as I also mentioned, my other bedroom is the same way. Two white wires are tied together, while only the black wires are wired to the fan. One black wire to the white wire on the fan. And the other black wire connected to the black and black with white stripe on the fan.

And not sure what you mean as I have no switch line.

does the switch actually control this box, or does it control a receptacle?

That box is not rated for fan support and should be repalce with one that is rated.

Have you looked at the switch box to see how many and what color wires are on the switch and in the box?

Why was a similar ceiling fan hooked up to it then? Light and all. Switch has a one black and one white coming to it.

No. It's as if you need something hooked up in the ceiling to get power to the switch. Almost that you need the fan to bridge the "hot", and once it's connected the switch will control the fan.

And I can't reiterate enough, the other bedroom is the exact same way. Surely I don't have the only house in the world like this.
