Do you still need help with this?
If so is it the main oven door? If you look at the plastic trim does it look like its broken?
main oven door plastic strip not broken
Ok if the door glass is back in place and the strip hasn't broken then all you need to do to fit the top plastic strip you need to push the right hand side of the bracket into the hinge at a 45 deg angle as this goes into a slot on the hinge.
Then you can push the rest of the strip down and it will lock onto the left hand side of the door and hold it in place.
Do you still have the manual as it shows you in there?
If not and you still cannot get it in let me know and I will upload the manual for you.
