Open the oven door 1/4 ways and then slide it off to reveal the hinges and the upper and lower screw holding them in place. After removing the screws I had to hammer and pull pretty aggressively to get the old hinges out and the new ones in. I even bent the frame a bit, but it didn't Impact my ability to tighten down the new hinges. Once they are screwed in, slide the oven door back on and it will lock in place
