Another run of door ajar probs.. they sure are cyclic, aint they?
Concensus, and it seems to ALWAYS work, spray the latch area with WD-40 while
working the latch.
The switch is "behind" the latch. After it frees up and works properly, I'd
then try to spray a greaseless cleaner everywhere BUT the latching pawls, as
WD 40 can attract gunky dust.
