Inspected about an 80-year old house today. It had some electrical issues. The oddest one was that I could not get the hall light to come on initially, but later I noticed that it was on dimly. Towards the end of the inspection, I was checking the oven which had been on for a while. It was just barely warm. I turned the knob up and out of the corner of my eye, I noticed it get brighter in the hallway. After playing around with the oven knob for a couple of minutes, I realized the hall light came on dimly when I turned the oven knob on. I could turn the hall light on brightly by turning the knob to “Broil”.
I’m not necessarily asking for an explanation of this. I just wanted to share this with ya’ll.
