The buzzing definitely seems to be coming from the motor. I put a plastic
tool to the casing and could feel it vibrating. However, I can turn it by
hand (clockwise) and see all the gears and striker mechanisms working.
It did manage to work briefly yesterday.. it did kind of a 'reset'. But
yeah.. not today.

Given the blown fuse I'd suspect a stuck mechanism, so the motor is stalled
and you're getting overcurrent. Try turning the motor by hand to confirm.
