if you look at the mechanical arms on the inside, there may be a spring looking thing that may have poped or lost tension, I'm sorry I don't know the proper nomenclature for the parts.

Now that I realize this isn't a common problem, I'll probably add the self-adhesive, thin foam insulating strips.
