Looks a possibility.
Could be the controller.
Ive had a window heat controller overheat many years ago on a nimrod. Filled the cockpit quite quickly and I got to the box before the CB tripped. It was easily accessible to a flight Engineer who knew his way around the equipment racks. Very different proposition on a modern 2 seater.
Lack of a mayday or squark is puzzling though!
