How To Install a 3 Way Dimmer Switch - Lutron

[@gastonlv]

Thank you, thank you!!! Those darned traveler wires! Glad you mentioned that. No one else had.

[@therenodummy]

I don't totally understand why that works but it does. Glad I could help.

Thank you for the critical piece of information up front about 3-way and 4-way switches. I purchased a 3-way dimmer switch and was attempting to install it where a 4-way switch was which I now know you can’t do. Replaced the other switch which was a 3-way and all good! Thanks!

I wasted a day trying to hook up this dimmer switch, so embarrassing. I tried ever way and finally gave up and went home. Thanks to your video it took me 5 minutes the next day. Their instructions leave out a lot. The need to hire you.

[@therenodummy]

That's great to hear!

[@mittenstudios8099]

The part where you said you can switch the traveler wires saved the day

[@therenodummy]

That's awesome. I'm glad it helped.

Thanks a million for this video. It saved me money and time and hassle

[@therenodummy]

Great. I'm glad it helped!

This is a great video. I am replacing a non-working switch on a three way with a Lutron 3 way dimmer switch for a very high front hall chandelier. This is the second attempt with the 2nd switch I purchased, and once installed, the light fixture glints on for a milisecond, then turns of immediately and never goes back on. Would love your opinion. Thanks!

Is the chandelier dimmable?

[@leighdencker]

@@therenodummy Isn’t that a brilliant question! I have no idea if the chandelier is dimmable. It replaced a previous chandelier and I think the new one worked for a minute (so to speak) and then stopped. It has been out for a couple years.

[@leighdencker]

@@therenodummy I think I am going to Home Depot and getting a regular switch. (not dimmer) The chandelier works with three separate light switches. I called Lutron and they said I need a 4 way switch! Getting complicated

[@therenodummy]

That’s probably the best idea. Yea it can get really complicated for us non electricians with 3 and 4 way switches

[@RightRudder]

Can the dimmer switch replace EITHER of the 3-way switches, or can it only replace the 'left hand' one on the wiring diagram you show at 0:23 into the video?

[@therenodummy]

I believe you can replace any of the switches. You may have to play with the traveler wires and swap them on the switch to get it to work right.

I have a single pole that only has two black wires. One seems to be the ground and the other is daisy chained to the switch next to it. Is it still possible to hook up the dimmer?

[@TrappedQue]

What would happen if I accidentally connect the hot wire to the traveler terminal? Thank you!

[@therenodummy]

I'm not sure how the light would act if you did. It wouldn't work correctly but I don't think it would do any damage.

[@DanQuigley-e9g]

I connected the switch with both wires on the right and now understand I need to switch the hot wire to the left side. My issue is the power works but the lignt is on in the off position and off in the on position. Do you think this change will correct that before I go and mess with it?

[@therenodummy]

My light can also be on in the off position. If you have multiple switches then there is no on or off position.

[@G-Ovalle]

Where does the common also connect too

[@therenodummy]

The common connects to the black/darker common screw. This screw serves one of two purposes depending on where it is positioned in the circuit run: Either it accepts the incoming black (hot) wire from the power source, or it connects to the black (hot) wire that leads onward to the light fixture.

[@wampaswomps3975]

On the switch do you know what is the little blue adjuster for?

[@therenodummy]

Its to adjust the dimmer range that helps controls the max brightness and sensitivity of the dimmer.
