Our ceiling fan fell today and in panic I forgot to check how it was wired before I took it apart. So I checked the light switch and it has a red wire & 2 black wires on it with 2 white wires that are capped, pushed into the back of the box. I purchased a new halogen light and wired it to the red and black wires in the ceiling and nothing happens. Please help !

You can ignore the wires that are capped inside the box. They were not in use and you don't need them to replace the fan with a light fixture.
You will need either the [red and white] or the [black and white]. It depends which one (the black or the red) goes from the switch to the light fixture.
This assumes there is only one switch operating the fixture rather than two 3-way switches.

Thank You for your reply. It ended up that the switch has the red & black attached to it and I ended up attaching the light to red & white and now it works just fine. Then my wife said to me can we hook a dimmer switch up to it as it is too bright. I hook a dimmer switch up to it and just like before - nothing. I followed the instructions and it's only two wires, what could possibly be wrong.

You originally said the switch that was working had a red wire and 2 black wires on it. I'm assuming the 2 black wires were attached to the same side of that switch - AND that the switch was not a 3-way.
If this is the case, attach both black wires to one of the dimmer switch wires, and the red to the other dimmer switch wire.
ONE MORE THING TO CHECK !! I'm not certain that all halogen lights can use the same dimmers as regular lights. Read the label that came with both the dimmer and the light fixture to verify that that light can work with the dimmer.

Thank You, all is well now after putting on a low voltage dimmer switch.

Dear Retep:

"I followed the instructions and it's only two wires, what could possibly be wrong."

This is what could go wrong

I hope you're not putting that dimmer on the same line that supplies power to the fan motor as well.

The fan motor is not designed to use a lighting control re-o-sat (dimmer).

To safely accomplish this project this application would need three conductors going to the ceiling outlet
(red = dimmer and light / black = the fan speed control and fan motor / white = the common or ungrounded conductor or neutral)

Putting in a dimmer to control a fan motor will GREATLY reduce the life of the fan motor and could possibly overheat the dimmer switch causing a melt down and God knows what else.

The question everyone is overlooking is WHY did the fan fall? If an electrician installed it he should be back there fixing the problem and installing it corrctly. Also he should thank his lucky stars that it didnt land on someone. If it was a homeowner who tried to save a buck on a job best left to a competent professional.............

To Christopher Sparks - The way I read this, the homeowner REPLACED the fan with a light fixture. So the dimmer simply controls a light - no fan is used. (I read it again and still think that's the case.)
To Retep - maybe you should verify this is what you did.
Thanks,

Dear rpxlpx:

You're absolutely correct ..... looks like another one I misread .... I think I need a vacation.

Oh BTW- my email address is listed in my profile - just for future reference.

(I often wondered why none of the other "advice givers" have never posted their email address}

I do most postings from work and don't want to receive unsolicited e-mails here for obvious reasons. I'll bet the same is true for other posters.
