I never saw a gasket screwed on, unless tou remove the interior panel to

I haven't replaced mine yet, but when one does, there must be a way to
attach it, instead of leaving it loosely hanging on the door, as the
OP described his.

(So whatever is done to attach a new gasket can be done to reattach
the old one, or if not, some other method can be used.)
