I have a 3 way switch setpup at each landing for my basement stairs.
I replaced the three way switch at the top, and it is a combo switch.
Single pole/3 way. tWO LITE TERMINALS AND A COMMON. i WIRED THE TWO
WHITE WIRES TO THE LITETERMINALS AND THE BLACK TO COMMON. aLWAYS ON
SITUATION DEVELOPED. tRIED SWITCHING ONE WHITE FOR BLACK AND
DEVELOPED A SITUATION WHERE THE LIGHT TURNS ON AND OFFFROM THE NEW
SWITCH, NOTHING ON OTHER SWITCH. tHE OTHER SWITCH IS TWO SEPERATE
CIRCUITS, AND A SINGLE POLE/ 3WAY AS UPSTAIRS. tHE upstairs single
pole controls the outside light and works fine.
I have tried the two white and one black in all configs poss on the 3
way part of the switch. The two single pole wires are wired as
beofore.
PLEASE HELP

The colors don't mean anything regarding placement on a switch. On the old
combination switch, was the bridge removed between the terminals of the
common terminals? If so, remove it on this switch

I was stymied by this myself. An electrical contractor estimator
actually fixed it for free and he did it with a meter and while
current was live. I had been kept running up and down stairs and
shutting off power with each trip to no avail. There was nothing wrong
with my switches but hookup is critical.

Try the following site, it might make it clearer how to wire the
switch. http://www.wfu.edu/~matthews/courses/p230/switches.html

Take a tester.

You will have one of the two situations.

One wire will be hot no matter what you do with the other 3-way

The other possibility will be that one wire will never be hot no
matter what you do with the other 3-way.

The wire you identify like this will go to the dark colored screw.
