OK... Something to try before you remove the whole stove.
Open the oven door and you will see the arms for the hinges... "Normally" you will see small "nail sized"holes in the arms.
push a small nail thru the hole and slightly close the door and you
should find another hole that the nail will continue thru.. thereby locking the hinge & oven door in an open position.
lift the oven door (with the hinge(s) locked)
The oven door should disconnect from the oven and you should be able to remove the door.
Most likely the hinge/arms have become bent/distorted from putting/setting pots and dishes on the open door.
A few places to try to find parts..
