I don't usually pay much attention to this when cleaning the oven, but the instructions for the cleaner say not to spray on the heating element. So today before cleaning, I decided to remove the heating element.
I guess that was a dumb idea, but the oven was off. When I was pulling out the element, it arced between the electrical connection and the oven frame. I turned off the circuit breaker and when I got back upstairs the element was hot.
Why is there still power going to the element when the oven is turned off? If this is a common design, it does not seem very idiot proof (as proven by me deciding to remove the element while it is plugged in).
To me it is like the difference between a properly wired light switch, where it is connected to the hot wire, vs improper, where it is on the neutral.
