What the F have I done?
The light switch in my daughter's room controls a ceiling fan and an outlet. The ceiling fan stopped working. Check for power at the ceiling, and my multimeter says yes, there's voltage. Figured the fan had died so I went and got a new one. Put it up and still no go. Still showing power to the ceiling. Checked the outlet with a lamp and it works (both plugs). Light turns on and off with the switch. What the heck is going on? Why won't the ceiling fan work? |
|
When you're checking the voltage what legs are you checking?
And did you try pulling the little chains? |
|
Whats the OHM reading across the switch with the wires unhooked?

Need voltage readings....assuming the switched outlet is working fine...maybe Neutral gone in the Fan tap?
|
|
Is there a romex at the ceiling? A white, black , and a bare copper ground?
Sounds like someone fished a wire up from a switched outlet for the fan. Check the connections in the outlet too.

I'm thinking the voltage isn't the issue though, if the outlet is functioning properly? Yes, voltage can be an issue. Lights may work but a motor is a entirely different thing. Also, check hot to return voltage. Hot to ground tells you that you have power to the outlet, It doesn't tell you if you have a return path. |

With switch on, voltage is 122v at both the ceiling and outlet. I just took the switch completely out of the equation, took the wires off of it and nutted them together. Same voltage at ceiling and outlet. |

Even the light kit on the fan doesn't come on. And yes, I pulled the little cords. ETA: What could I plug into the outlet to test draw? I plugged in a computer with a 500w power supply and it turned on. |

In for some asshat reversed wire colors and the Op just needs to swap the black and white.... I found this in a house someone had used white for the hot from the plug up to the ceiling fan.

I would guess, if only because the old fan in there (with light kit) worked just fine for 8 years. (and I installed that one too) |

your power is fine, you fan is bad Yeah, I doubt that, since I bought a new one. I know my first post was long and all... |

you should check volts with the hot leg and the neutral leg of the circuit
typically the hot is black and the neutral is white |
|
You keep saying ground to hot, you need to tell us what you get from neutral to hot.

your power is fine, you fan is bad Based on information to date I would go with this or incorrectly installed. |

If you are getting 120 on the wires in the ceiling, either you fan is bad, wired wrong or as others are saying...your missing something {pull switch} :) |

At the outlet neutral to hot? 120v. At the switch box neutral to hot? 120v. At the fan neutral to hot? 0v. Broken neutral somewhere? Guess I'll have to climb up in the attic. |

I've had this problem before. The power wire had rubbed through the insulation and was touching copper. I got resistance and power but when the current flowed it got drained out through the copper. Trace the wire and look for bad spots.

I pulled the switch of the wall, connections look good there. Outlet is the end of the leg and it reads right between the hot and neutral. Guessing it has to be in the ceiling. Oh well. At least it's not 120 yet and the attic shouldn't be completely unbearable. |

Most likely the switch goes to the outlet first then runs to the fan. Either that or you have a squirrel/possum to take care of. |

Could be...I had a call to a guys house that lost his flood lights...turned out either a rat or squirrel chewed up the sheathing and it shorted out.....I never found the carcass, and there was NOW WAY that animal could have lived through that........

So you have ONE blk/wht/bare there? k...so it's fed from the switch.....how many sets are at the switch? |

Quoted: The only way you can get 120V hot to ground at the fan but 0V hot to neutral would be a hot to neutral short near the fan but that should trip the breaker and if it is wired to the fan then to the outlet you should see the same scenario at both.

I ALWAYS make the mistake of looking for the hard shit....ends up being something stupid like a tap, stab-back came free....or the damn pull chain |

Need to start a wager on who is right....lol maybe a paid membership, paid by the OP
Fixed, OP should pay for membership for our knowledge if it turns out to be pull chain |

Hmmm.
I'm telling you, it is one of 2 things. Either a wire was ADDED from the plug UP TO the light.....check splice INSIDE OF RECEPTACLE BOX OR a wire was fished from LIGHT DOWN TO THE RECEPTACLE....check the splice inside the LIGHT BOX. Why do you people have this guy crawling around in his attic?
