I’m cleaning this cabinet above the range/micro and noticed this mark on the back. I mostly keep cooking oils, vinegars, etc in here. Does this look serious?
Update: well it ain’t pretty, but it shouldn’t burn the house down. For anyone concerned, my electrician approves. Thank you all for your help today.
Aha. Great question. Nope.
Weird, I would probably get a noncontact probe and see if there’s power, then cut power and see if there’s something behind the drywall.
