Hi *****,

I'm an electrician and can help you with this problem. First - shut off the power. Check your wiring as I describe the connections below.

If this is the only switch operating the fan and light, it should be wired as a single pole in the direction sheet. That is as follows:

1) one black wire - it should be connected to the "hot" power source, 2) one green wire - it should be connected to the bare / green ground wires & switchbox (if metal), 3) one red wire - it should be connected to the fan hot wire, 4) one yellow wire - it should be connected to the light hot wire, the remaining wires (yellow with a "3 way label" and red with a "3 way label") should not be connected to anything and capped with a wirenut.

The wiring changes if you are using a second switch to operate either the fan or light (download & view the wiring diagram provided here to follow along with my text). In this case, the hot wire from the fan or light would connect to the black screw of a standard 3 way switch, and the remaining two terminal screws on the switch would connect to the red / red with 3 way label - or yellow / yellow with 3 way label pair. Power and ground wiring on the dimmer black and green are the same as the single pole wiring described above.
I hope this helps & good luck!

I have a dimmer switch with a two black wires and a green wire and want to replace it with a dimmer switch that has a blue, red, black and green wire. I am not sure what to do with the blue wire?

You have bought a 3 way dimmer switch. Do not use the blue wire if it is not going to be on a 3 way circuit. Just cap or tape off the wire with electrical tape. the green is the ground and the two blacks you have connnect to the black and red.

House has 2 blue wires and one black.. this switch is one of 2 that controls the hall light. my switch i am installing has 1 black 2 red and the green ground. which red goes with which blue wire..

At this point either. Once you hook up the switch test the switches on both sides. Make sure each one turns on and off if that makes sense. If the blue wires are on wrong one switch will only work if the other one is on. If that happens reverse the blue wires and that should fix it.

Usually there is only a red wire when there are 2 switches for the same light (a 3way) if that is the case you need a switch that is a 3 way, there are some 3 way dimmers. But you do need to replace both switches.
The other thing may be at the light fiture end. If the red wire is in there it should be connected to a black wire, which should only be connected to each other, that way the curcuit is broken.
or to say one white wire is connect to the light, a black wire connected to the red,(taking power to the switch) a black wire is returning from the light switch is connected to the light. (if it is a 3 way its different...)
Confused... 1st confirm if its a 3 way, second confirm if there is a red wire at the light fixture, from there I can guide you more.

Ok I am installing a dimmer to replace a switch I have three wires red white black and ground I run the dimmer an it doesn't work

I suggest contacting Lutron's tech support center at 1-800-523-9466. They're available 24/7 and can help you out.

Having said that, can I assume that the red, white and black are all coming from the same romex? If so, the trick to doing this properly is to understand how the 3-way switch at the other location is wired up. In other words, of the red, white, and black wires... only TWO of those wires are connected to the other 3-way switch (I'm assuming this is a 3-way circuit given that you bought a 3-way product). Once you've identified the color of those two wires, on the dimmer, attach each of those two wires to one of the red wires coming out of the dimmer. The remaining wire coming out of the wall (red, white, or black) should then connect to the black wire coming out of the dimmer.

Ok the RED is Phase and the Black is Neutral... Green is Earth. you have an IN, Red wire, and an OUT Red wire, the rest just go color to color. So in the socket, one Red wire goes to one Red wire from the dimmer, the other Red wire in the socket, goes to the other Red from the dimmer, then Black to Black, and Green to Green. Be careful do NOT work on it live.

I am replacing an old dimmer switch with a new one. The old Leviton has 4 wires. One red, two blacks with one listed as 3 way wire which is not being used, & one green. The red is connected to white,...

ON one side of your switch it is connected with a small peice of metal or should be. That is why it only explains 3 wire instead of 4. If you look you can find the one you need with 4 spots to put your wires. Just look or ask your store for what you need. They can be very helpful in helping you find what your looking for. Hope this helps.
