Hi Kerri,

First, be sure the power is off at the circuit breaker. If I understand you correctly, the dimmer switch has 2 wires. Some have 4 wires.
Connect the black wire to the black incoming wire using a wire nut. Twist the stranded wire tightly and tighten the wire nut as tight as you can get it. Attach the red wire to the white incoming wire the same way. Be sure the gold ground wire is attached to something. Either it will be connected with other gold wires or it will be grounded to the box if the box is metal.

Hope this helps. If it does, I'd appreciate a vote or comment. Thanks,

Handie Andie

Leviton IPI06-1LM 3 way dimmer switch- not dimming


Hi Sara,

Please read this entirely before attempting.

I am an electrician and would like to help you with this problem. You have provided great detail of your situation, yet I am confused about the statement describing how you wired it:

"-Red Wire (used in 3-way installation-tagged) from switch to the red wire in wall."

Before checking wiring, be sure to shut off the power to the circuit.

The "tagged" wire should be the one you identified with tape (when you removed the original) that was connected to the dark colored (called a "shunt" or "common terminal") screw of the switch.

In a 3 way installation, both red wires from the dimmer switch are used. In a single pole installation, only the UNinsulated red wire is used and the insulated wire is not.

To which wire do you affix the "tag"? If it was a short wire that ran between the the bundled black wires and the shunt terminal screw of the old switch, then the dimmer switch's black wire should be combined with these bundled black wires. One of the dimmer switch's red wires would be connected to the red wire in the box and the dimmer switch's last red wire would be connected to the remaining black wire in the box. I understand that this is the way you have it currently wired - but without being able to dim.

If this is all correct, did you check / change the Minimum Brightness Adjustment setting for the switch as detailed in Step 7 of the directions?

"This Dimmer incorporates a
minimum brightness adjustment
that allows you to set the level of
light when the slider control lever is
in the lowest position.
Move slider to the lowest position.
Using a small, insulated screwdriver,
rotate the adjustment screw as
shown until the desired level of
minimum brightness is obtained."

I hope this helps and good luck!

I believe my power source is in the ceiling. I just want to wire a light but use a leviton switch and dimmer at the wall. Can't figure this one out. Can you help. There are two red wires, one black and...


Question needs more details. Let me answer as if you have one light and one switch, and one cable coming into switch box from ceiling.

Usually a switch-dimmer combo operates 2 different Loads (lights).
One light is controlled by switch, other by dimmer.

If power source is in ceiling, then one cable enters switch box.
Cable has black, white and ground wires
Old switch had 2 brass screws where black and white wires connect
Black wire brings Hot down from ceiling, and white wire connects back to Load (fan).
Neutral wires are in ceiling box, and not inside switch box, and are discussed.

With new dimmer: Black Hot wire from ceiling connects to dimmer black wire.
White Load wire connects to one of the red wires.
The other red wire goes to another Load, which is unknown at this point.

Add a comment for more free help. Say what cables and wires enter box, and what Loads you are controlling. Also add exact model number so expert can reference manual. Levition instruction sheets and manuals usually have toll free number.

Also take advantage of fixya expert assistance live.
For a price, expert works with you via e-mail or phone while you work on circuit or any do-it-yourself project.
Fixya is always less expensive than a service call.

HI,
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.

I think I have a Leviton double pole dimmer switch. It used to operate track lighting along with an on/off light switch in the same room (different entrance). I replaced the track lighting with a fan...


You mention a dimmer and a 2nd on-off switch.
You purchased a 'double pole' switch which I believe is a 3-way switch.

3-way switch has 3 screws (plus ground screw which will not be mentioned further)
3 screws on 3-way switch = one is dark colored, and 2 are brass colored.

You can guess. There are only 3 wires and you can keep trying different combination until both switches work. Do not change wiring on 2nd switch and sooner or later the right combination will appear.

On the other hand, electricians test wires using ordinary tester, before connecting anything.
If you want to test, it takes 3 ez steps.

Here's what I would do.
1) Look at wiring on 2nd switch.
Notice switch has 1 dark screw and 2 brass screws.
If you can identify the two wires on the brass colored screws, these are the 'travelers' and same two wires connect to brass colored screws on new switch. And then last wire connects to dark colored screw.

2) You have noted the wires carefully on dimmer, so remove dimmer, and separate wires for testing.
2nd switch is moved to down position.
We are NOT going to test wires on 2nd switch.
We are just testing wires at old dimmer.
Turn on power.

Power is on.
2nd switch is in down position.
Test each wire to bare ground wire.
One and only one wire will light up the tester.
Mark this wire.

3) Change 2nd switch, and move 2nd switch to up position.
Test each wire again to bare ground wire.
Again only one wire will light up tester.
Mark this wire.
If same wire lights up tester each time, then this is the Hot wire and it connects to new switch dark screw. And the other two wires go to brass colored screws.
If a different wire lights up each time, then these two wires are 'travellers' and they connect to each brass colored screw. And the last wire connects to dark colored screw.

I just purchased 2 of these dimmers from ebay but they do not have the instructions. Both are exactly alike and have 2 wires. How do they install?


You posted under Pass and Seymour rotary dimmer that has two wires.

If your dimmer is like other rotary dimmers, it has a black and red wire.
Or it has 2 black wires.

If your switch has 3 wires, then the dimmer will not work.
If your switch has 2 wires:
Probably both switch wires are black.
One of these wires goes to Load (lights)
The other wire is Hot from breaker box

If dimmer has 2 black wires, they connect to either wire from switch.

If dimmer has black and red wires,
> dimmer-black connects to Hot from breaker
> dimmer red connects to Load
> green (if available) goes to bare copper wire

Recommendation:
If you do not know which wire is Hot from breaker, simply hook up dimmer and see if it works.
If it doesn't, then reverse the wires.

If this information does not fit your specific dimmer, please answer back with more details and we'll get it working.

You're correct. The dimmer switch was not made for that fan.

The Green is ground > so you're right there too. I assume other plugs nearby are working when dimmer is on. Check that to make sure.

By your description, I assume there is NOT another switch or dimmer that connects to same light. If so, you need a 3-way switch and the following instructions are void.

I suspect when you wired the new fan, that you saw the red and small black wires in the ceiling box. Did you connect the fan and light to those wires? If so, the following information will help you wire the switch.

Your incoming Hot line is probably the larger black wire that connects to Dimmer black >>> this wire will connect to either screw on the new switch

To test Hot wire for sure: Take out dimmer and mark wires for identification. Separate wires. Turn on power and test each wire to bare ground. Tape tester leads to wood sticks so hands are away from power. You'll be fine. Tester lights up on Hot wire.

Next: The smaller black and a red wires are a toss up.

Here's how I would proceed. Connect the black Hot to either screw on switch. Connect red wire to other screw. Put wire nut over small black. Turn on power. Flip switch. Check both lights and fan to see which works with red wire.

Next reverse the toss up wires. Put wire nut over red. Connect small black to switch. Check both lights and fan.

If red and small black control the light & fan, then connect them together on the same screw, and you're done.

If you want to control the fan and light separately, buy double switch, and then Hot connects to dark-colored screw on one side of switch, and red and small black connect to two different screws on opposite side of switch.

How to install a dimmer switch


This is a 3-way switch, made to control a light fixture that is also controlled by another switch in a different location. A typical example is a ceiling light fixture installed in an upstairs hallway, which could be controlled by switches at both top and bottom of the staircase.

The green wire in your switch is the ground connection, and joins to the green insulated or bare copper ground wire in the switch box. The red wire is the common connection. It connects either to the incoming AC hot wire from the electric panel, or to the hot terminal of the light fixture, depending on the switch location. The two black wires are traveller connections. They connect to the traveller terminals of the other 3-way switch.

If you purchased this switch as a replacement for a regular single-pole toggle switch or dimmer switch - one that controls a light from a single location only - then this isn't what you need and you can't use it. You'll know if you have a single-pole switch because it will have only three wires or screw connections. Return it and get a single-pole.

To install this as a replacement for a 3-way toggle switch or dimmer, connect the red wire to the wire going to the common terminal of the original switch. This will be a black- or brass-colored screw on a toggle switch, or the different-colored (not green, that's ground) wire on a dimmer. The black wires connect to the wires that go to the traveller screws (copper-colored) on a toggle switch, or the same-colored wires on a dimmer. It doesn't matter which traveller wire connects to which.

Note that if you're using a 3-way dimmer, only one of the switches can be a dimmer. The other switch has to be a plain old 3-way toggle.

When you take the existing switch out of the wall, the existing switch will have one black screw and two gold screws. The wire that is connected to the black screw of the existing switch (probably on of the black wires from the box) connects to the black wire on the new dimmer. The other two wires (one black and one red from the box) that are connected to the two gold screws on the existing switch will connect to the two red wires on the new dimmer. Basically, wire from black screw goes to new black wire and wires from gold screws go to new red wires.

House has two black and one white. dimmer has one black, one green and one red. WHat connects to what? THanks


Black wires are the hot side the power line, white is the neutral, and green is ground. On your dimmer, the black wire is for the AC input and the red wire is the output to the lamp you want to control.

If you are replacing an old switch with the dimmer, the two black wires will be connected to the screw terminals on the switch. One of those black wires is the AC feed to the switch, the other black is the one that goes to the light fixture. You'll need to determine which is which so you can hook the dimmer up correctly.

For a few dollars you can pick up a tester that lights and chirps when it's near a hot wire. Turn off power to the light circuit at your circuit breaker or fuse panel. Remove the old switch and disconnect the wires. Make sure the bare ends are not touching anything and turn the power back on. Hold the tester near each of the black wires. One of them will cause the tester to light up and the other one will not. The unpowered wire is the one going to the light fixture. This one connects to the red wire on the new dimmer. The hot wire is the feed that connects to the dimmer black wire. The green wire on the dimmer connects to the other green wires already in the box. Turn the power off again and make your connections using UL approved twist-on connectors (wire nuts), which probably came with the dimmer. Fit the wires and dimmer back into the switch box, secure it with the mounting screws, replace the cover plate and turn the power back on.

Voila! You'll have a working dimmer. A Google search for "installing dimmers" will turn up several links to sites with good pictures.

Trying to hook up a dimmer switch it has a red black yellow and green wire the box has a black white and ground which wires get connected together?


For a single-pole installation:

1. Connect the 2 white wires together (one from the source and the other to/from the light fixture) - 2 wires
2. Connect the black wire from the source to the black wire on the dimmer switch - 2 wires
3. Connect the black wire to/from the light fixture to the red wire on the dimmer switch - 2 wires
4. Connect the ground wires - 3 wires
