Hinges needed to be replaced having been overstrained

I paid for an online advice service (Just answer)after failing to remove the hinges. The advice was not remotely helpful and I have asked for my deposit back.

Here are the steps:

Remove the door: Place the two tiny studs taken from the tongues of the new hinges in the same holes in the old door.
Holding the door just open, lift up and out to remove the door from the oven.

Lay the door on its inside surface, then remove 2 Phillips head screws from both the top and bottom edges of the door to release the front glass assembly. The hinges can now be seen.

Turn the door over and remove four Phillips heads screws to release the hinges, replace with new hinges.

Replace the two small studs in the hinge tongues and replace the door reversing the removal process. Remove and save the two studs (handy if you ever want to clean the glass on the inside)
