I am a fairly savvy DIY and am perplexed on how to proceed. I want to remove one 3 way switch with a red, white, black and ground. I am assuming the white is a neutral, but does not appear to be part of my bundled neutrals in the back of the box. When I tie my red and black together and cap off my neutral, then install my new switch at the end of the line box, my new switch does not work. How do I remedy this? In the box I want to keep, I do have a red, black, white as well along with a ground.

  • There are some code requirements on the number of switches needed in a room, on stairs, etc., are you sure you can remove one of the three way's? Can you provide pictures of the two switch boxes?

  • To keep functionality and maybe also to be code compliant, use a 3-way dimmer. I didn't even know that they existed until my new house had one already installed.

  • What make and model of smart switch do you have, and is taking it back and getting a different one an option? Can you post photos of the insides of the switch boxes involved please, for that matter? Mar 7, 2020 at 21:01
  • If the white goes to the switch, it is not neutral. Are any other cables in the box? A cable is several wires together in a common sheath. Describe if you can the cables in the boxes, not just the wires going to the switches. Mar 8, 2020 at 0:04
  • There are a few ways the cables for 3-ways can be routed, and sometimes the wrong colored wires get used, so to clearly answer your question we need to know how many 3 conductor and 2 conductor cables are in each switch box, and which colored wires are attached to which colored screws. Pictures work well for that. Mar 8, 2020 at 15:05
