how do I put the door screws back after cleaning. I had a spill over and cleaned the inside of the glass but cant figure out how to put the screws back, especially 2 triangular parts about 1 1/2 " long that came out while disasembling. I have 2 long screws that go at the top of the door and 6 smaller screws that go at the bottom, 3 on each side of the door. Please advice asap. Can't use my oven.
