Having some trouble with a breaker switch and everything thats part of that circuit. Out of the blue, some lights stopped working along with everything else that is hooked to that specific breaker.
I flipped the switch, tightened the screw a bit and then some of the lights started working again (garage, dining room). Then when I went to turn on the front door light, the garage/dining room lights went off and everything on that circuit wouldn't come on. I tried this a couple more times, removing the switch, making sure it was secure on the main panel but same issue.
Could this be linked to a bad switch and could simply replacing the switch be an easy fix? I'm guessing not since some of the lights do power on. Other possibilities?
Dont believe there is a GFCI on this circuit.
Attached a couple pics of the breaker on the main panel and after I've pulled it off.
