Broke when I slammed the door shut after a broiler fire, last October. Finally got the part delivered, almost 11 months without the main oven. (Damn Covid!)
Had to remove the oven door, flipping back a U-shaped clip on each bottom hinge. The door is heavier than you'd expect. Two Phillips screws on the face and two on the sides were removed and the top bracket lifted off, glass replaced, shiny side up, (inside), slid into lower "V"s. Re-attach bracket with the four screws. Easy-peasy.
A thorough cleaning of the inside glass panels is recommended before assembly.
There is a video that shows how to do this with a British bloke, who speaks very rapidly in a strong accent. I couldn't understand a word. Not tough, though.
