My oven door seems to have dropped so that the stricker is not hitting the catch in the middle thereforeyou have to lift the oven door up and slam it so it shuts. Even then the door sometimes pops open on its own!!!. When the door is open it moves quiet a lot on the hinge. My question is either the hinge is worn, or the pin that the door sits in (ie this part) is worn. I cant seem to get at the two individual screws that hold the two seperate hinges in place to take the door off to have a look? Any ideas? Thanks
