I am in the middle of going through this right now. Take a look at this post:
I took pictures of the doors closed and tray removed (looking down through the glass at the region where the upper door meets the front door. I also took pics of all of the connectors on the lid.
The resolution from GF is that they suspect the black cable on the lid is bad. They’re sending a new one with installation instructions. I’ll post back here once I’ve gone through the install to let you know how it went.
Good luck!
