I'm attempting to wire a 3 way switch with a dimmer

I'm attempting to wire a 3 way switch with multiple lights and a dimmer. I followed the diagram supplied by the dimmer switch and it seems to work except for the fact the the non dimmer switch only works when the dimmer switch is turned on. I need to find a solution that will allow both switches to turn the lights on and off.

Hello Chris,

What has happened, is that you've got th two "traavelers" reversed on the plain toggle switch. These are the RED and BLACK wires. turn off the power and reverse the position of these wires and the switch should work correctly from either the Dimmer switch or the plain switch.

Here's a link with a diagram, which might not exactly match your circuit configuration, but you can also watch a short video that explains how 3-way switches work.

It is just a matter of getting the travelers on the correct screws in order for the circuit to operate properly from either switch. Also, depending on the type of dimmer you've installed, the other switch will only turn the lights on at the dimmer setting that you've left the dimmer switch in. So be sure that you're not turning the dimmer all the way down before you shut it off (at the dimmer) otherwise, the other 3-way switch won't be able to turn the lights on, regardless of whether you've got the travelers in the correct locations.

Remember to turn the power off to the circuit you're working on while you rewire it and flip the breaker back on when you're done.

Load between 3 way switches and line entering switch box. Breaker trips when both switches in down position


Test your wires.
Somehow you've got a neutral wire, or ground wire, or shorted wire connected to one of the switches.
Without a wiring diagram, best place to start is identify hot wire from breaker.
There should be only 1 hot wire connected to the switches.
Disconnect the hot wire. Then test hot wire to each other wire and screw terminal. Tester will light up on neutral or ground fault. That will narrow down the suspects.

I HAVE A DIMMER SWITCH BUT NO MANUAL AND I THIN ITS MISSING A WIRE


A standard dimmer switch only needs two wires plus ground, just like a standard switch. If you are replacing a three-way switch with a dimmer, then you need a three-way dimmer switch (which has three wires). 4-way switches have 4 wires. Note, with 3-way or 4-way switches you have multiple switches controlling the same light, but only one of them can be a dimmer. good luck, Al K

You have to run the 3rd wire all the way to the switch, whether it hits any lights or not, I have seen electricians pull a single wire in to the box with the 14/2 and that would be the jumper. This will work on any lights, and the lights only need the 2 wires, It is just the switch that needs the 3 wires. Good luck.

How to wire 3 switches in a 3 gang box


WARNING: Do not attempt to do this work unless you completely understand the information provided below. If in doubt call an electrician.
Always make sure the power is disconnected from all possible sources before making any connections. Your description of the problem indicates that there may be multiple power wires coming into the same box. In that case local codes may require that the box be partitioned to prevent exposure to voltages up to 220 volts.
You need to determine where each wire goes to know how to connect them together. You cannot rely on color alone. If the power supply runs through the box to the loads then most (but probably not all) of the white wires will be connected together. If the power runs to the load boxes first then none of the white wires in the switch box should be connected together. They are used to run the switched/dimmed power back to the loads (and should be taped to cover the white in the box). In that case each switch has its own power input and they should not be tied together. A wire (could be black or white with black tape) brings power from the load box, gets connected to the input terminal of the switch and the corresponding black wire carries the switched power back to the load. The fan/light switch will have one power in and a switched power out for the fan and another for the light. The 3-way will have one "power" in (or it could be the final power out to the light) and two "carrier wires that connect to the other 3-way switch. If the power supply goes through the switch box then there will be at least 10 wires in that box. In that case see the attached diagram: a5fa64a.gif
