Sounds the same as B1641:
WARNING DO NOT FORCE OR YOU WILL BREAK THE DOOR.
Remove door from oven, lay down on handle.
DO NOT undo any screws. Grip internal glass at hinge end and pull up and away.
You will then see why handle end is tight, it is secured with screws though glass.
Once the glass is removed you can see all of the screws that you need to remove to take it all apart.
