I had maintenance turn off my breaker and fix the pull tab on my ceiling fan. Then turned it back on... Few minutes later.... I turned on a light switch and it made a sizzling noice! Maintenance came back and flicked it off and on about 20 times and said it was fine and could have been a power surge! Is that true or should it get replaced??? Also i might fix myself..... But the wires are confusing.... What would happen if I get them mixed up?

    Good for you. Asking questions before you dismantle everything and get into trouble. As @Harper mentioned, take pictures before doing anything. If the experts here (not me) know where the wires were, they can tell you where they should go. Good luck – JACK Oct 24 '19 at 12:51

Shoot photos of the wiring and let us walk you through it.

The usual place people get derailed is in 3-way switches; they count on the screw positions or wire colors meaning anything at all. The screw positions vary on every switch, and the colors are worse than random in 3-ways. I even recommend you mark the travelers with yellow tape; doing so makes things easy.

Even on a 2-way you sometimes see more than 2 non-ground wires; almost always two always-hot wires and the installer just used the switch terminals as a lazy way to splice them. More logical is a pigtail; but a novice switch replacer usually does not have the supply of wire, wire-nuts and stripper needed to do a pigtail.

But the #1 complication is dumbth; people not being conscious that they have outranged their skills and thinking they can just blunder about and get lucky. It's less of a risk on switches, but on other things, experientation can lead to many combinations that work but kill you later. Skills are so easy to acquire that I advise to do so.
