I need your help. I disassembled the door to the oven in order to clean the glass (3 pieces of glass) and now I am unable to reassemble the door.
Not sure what to suggest other than you call someone who repairs ovens. The only other thing I can think of is to disassemble and reassemble it until no parts are left over.
You've already got it disassembled, so maybe the next step is to try to assemble it. If this does not work, keep assembling and disassembling the leftover parts until you understand your oven door completely!
There's probably a schematic out there that shows what part goes where. While not necessarily helpful, it might help a little bit.
People who learn how to disassemble iPhones for the first time use the procedure I've described above. They keep assembling and disassembling until they've learned all the steps perfectly.
I've never disassembled an iPhone, so I'm basing this on what I've heard, not on actual experience.
However, people who repair ovens professionally will know so much more than I do. You might consider hiring such a person and watch what they do!
Here's a YouTube video that may help:
All the best!
