Replacing old ceiling fan wiring issue

Posted by mooie (My Page) on

When I took down the old cheapo fan the PO installed I noticed that they used only 2 white wires to make it work. IIRC,they had it white to white, and blue and black to the other white. And it worked fine. Well until the blades started to fly off in different directions, that is.. : )

My new Hunter has the green ground wire, a black, black with white stripe, and a white wire. I've tried switching them from one to the other but I'm still not getting any juice from the switch. However I did notice that there are a couple black wires pushed way up in the box that have been taped off for many years judging by what the tape looks like. I feel like I should be using at least one of them, but then again the PO only used the two whites. What am I doing wrong? Thanks!

RE: Replacing old ceiling fan wiring issue

What you have is a common configuration which is called a 'switch loop'. Power comes in on one cable with the black then connected to another cable which takes the current down to a switch, returning it on the other wire in that second cable.
Connect the white from the fan to the white from the power source. Connect the black and black/white to the white from the switch. Connect the green to the other grounds (usually bare wires in the box.
The fan should then operate as before, with both the fan and light turned on and off by the switch. (If no light fixture is to be installed, do not use the black/white striped wire)

Thanks Randy, I'll give it another try after I get rid of this mornings frustrations! : )


RE: Replacing old ceiling fan wiring issue

Technically the switch loop is wired backwards... it's defined in order to avoid exactly the same problem you just encountered.
