for the most part, its an easy job, but there are times the slots don't line up with the plastic shroud and the front cover....sometimes you have to attach the hinges first, then attach the door.....
with the front off as you have it, trying installing the door, or at least the hinges, to see if something might be in your way.....
you can put the door on first, close the door, then install the front cover....then open the door and install the screws....
seems like you got a fighter there on your hands....
