Thanks for all the posts for my question.
I did find the tech sheet .
It appears that , according to the sheet, the panel was incorrectly installed at the factory.
The panel has tabs with holes that the two screws mentioned in the TS should secure it to threaded tangs
(Or brackets) that are on the hinges.
This unit has the tabs for the panel sitting ON TOP of the tangs instead of on the underside of the tangs.
Can't pull forward on the lower edge of the panel far enough to have the tabs clear the tangs.
Of course this keeps the panel from dropping down.
Anyone run in to this before, or am I missing something? (God knows wouldn't be the first time I
Couldn't see the Forrest for the trees!!!
