New to the forum but not new to electrical but having some medical conditions now.
I have a switch box on the first floor with a dimmer switch and a 3 -way switch ganged with 2 cables and they are both 2 wires and ground. I was replacing the switch (single pole before) because the light would only turn on and off if that was the switch you turned it off with. I could not turn on in the kitchen and go to either of the other two switches to turn it on.
I replaced the switch but now the switch works but the garage and other places that are on that circuit are off.
Please help the garage has my freezer/frig and it has been of since yesterday.
Thanks, shocker
