Frustration with Three-Way Light Switch
After 10 years a three-way light switch stopped working. I replaced both switches, but I must have missed something because the switch only operates 'sometimes.' We have to put switch A in the up position so that Switch B will work. Did I invert the switch leg? I attached the new switches using the exact same order as the old -- which had worked flawlessly for years. Therefore, I'm wondering if something else is at fault (no pun intended).
