An obstruction can stop the door meeting the cavity as intended. Check only when the oven is cool, without forcing the door against it.
What the observation means
A protruding tray, loose packaging or residue at the seal is different from a damaged hinge. Removing an obvious loose obstruction may be an owner task, but dismantling the seal or door is not the same operation.
A useful next step
Follow the manual's cleaning and loading instructions and confirm normal closure before using the oven again. If the door still sits unevenly, request assessment. Do not compress the seal with extra latches or rely on leaning against the door while cooking.
