Question too many wires

I want to put a dimmer on a hall light that is controled by a swith at the top of the steps and a switch at the bottom of the steps. When I took the plate off the switch had a red, white and black wire (green too for grounding). The dimmer only had a black and white and green wire. What do I do with that red wire on the original switch?

Thanks,

John

What you need is a 3-way dimmer. Return the one you bought and pick up a 3-way version. That will have enough wires for your application.

And be sure to label which wire is connected to the black screw before you remove the old switch. Otherwise, you'll be back here asking what to connect to what, and we'll tell you that we don't know.

Good point John. Or if it doesn't have a black screw, (older switches may not), look for the screw marked "common" and make sure it gets connected to the "common" screw on the new switch.

one step forward .....

Well I got the new three wire switch, found the common terminal and wired it up. It worked but where I tried to turn on the light from the other switch it wouldn't work. If I turn if off with the dimmer I can't turn it on with the switch. I'm confused!

You have not correctly matched the common wires. If you correctly identified the common wire on the old switch, perhaps you didn't correctly identify the common wire on the new dimmer.

That is entirely possible John but I thought I tried all the combinations.
