I have a three-way light switch that is exhibiting really odd behavior.
Sometimes it works and sometimes it does not. For example, just now the following happened.
Lights are off. I go to switch A and flip it back and forth. Nothing happens.
I then go to switch B and flip it. The lights come on.
I then return to switch A and flip it twice. The lights first go off, then come on again.
For about a week, neither switch was working and lights just stayed off.
It is very strange. What might be the problem here?
Note that these are dimmable lights and that there are a lot of light switches in the house so it is possible the circuit is tied into something else. Can you have a 4-way light switch?
