I just recently installed a 3 way switch in my house to control the light in the hallway, it was working fine?

Question

the last two days then it just stopped working all together, what went wrong ?? any suggestions.

Answer 1

1) a wire connection could have come loose

2) the black and white wire could be touching, which would have caused the breaker to trip or a GFI on that circuit to trip.

Answer 2

Did you check the bulb?

Answer 3

Loose wire,

of you ahve either tripped a circuit brekaer or a GFI outlet that is associated with the curcuit. Check  the breakers, ckeck ALL the GFis.

Oh, of course the bulb might be burned out too!

LOL
