Hello, ZDA 45 Double Oven -I have removed the doors for a good clean up of my oven. I have managed to refit the bottom lower oven door, but cannot get the top oven door back in place. There is obviously a correct method to locate the long upper arm of the hing then push in the bottom retaining part of the hinge, do you have a procedure or pictures that would help me to refit the door please, thanks and regards Alan.
