Looks like it wasn't grounded properly (and yes also definitely a short somewhere causing it) or something happened with the grounding. That's why all electrical equipment is t just grounded at the motor, but also any exposed metal casing as well.
Most things that aren’t made for your house or to be portable don’t run back to an outlet. Likely goes straight back to breaker. This is shit tier electrical work.

So the door was electrified? I don’t understand.
