Hinge on one side seems to have slipped back into the housing a bit not allowing the door to close fully. How do I access the inner housing, and what do you think caused it to recede?
The hinge on the unit is screwed to the cabinet and to get to it you would need to pull the wall oven out some. What you may want to look at is if the oven door liner may be warped where the hinges go into the door. If warped then the inner door liner will need to be replaced. If not then the hinges would be the issue.
