I was swapping out the gears in my garage door opener and when I plugged it back in I heard a pop and some smoke, unplugged it immediately and realized that I had pinched a wire with a screw that I had totally not noticed. I can see on the circuit board that something blew out on it and it looks like the wire leads to the light that is supposed to come on when the garage door opens/closes. The light doesn't work but I am honestly not sure if it worked before as the others don't but the garage door itself works fine.
I wrapped the wire that I messed up with electrical tape to prevent any raw wire from being exposed but my lack of electrical knowledge has me worried that this is a dangerous situation. Should I be concerned to leave the garage door opener powered?
