  buzzing definitely seems to be coming from the motor.  I put a 
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 

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.
