How's the best way to find out if there's any wiring that might be overheating inside a wall?
For the last few months, I have been waking up once a week or so between
4-5am smelling what smells like cigarette smoke. Today it was more like hot wood - like when a dull saw blade starts burning the wood. As soon as I wake up, there's no smell. It's not like it's coming thru a window- more like right next to me. No one else has smelled it and since the smell was always gone right away, maybe it's a dream, but never heard of having a smelly dream.
Anyway, first time I smelled it, I took it seriously and checked all the electrical in the house. All looked OK. No smell at any outlets, cords, electronics, appliances, no hot cords, etc. Most everything is off at that time. No one uses any hot hobby tools, only thing that burns is gas stove and water heater - both fine. No smokers in the house or neighbors. Garage is fine.
Already checked for rat-chewed cables in the attic, pulled covers off receptacles, cb panel, traced all exposed wiring, etc.
