Middle is how we normally have it set for both (the "5" has a little box
around it) and that has produced acceptable temps. I've since set it
colder of course--fridge side is all the way down now. Under normal
circumstances that would produce freezing on some foods. Before I started
cleaning the coils--just a half assed job so far--it's late at night and I
will do more tomorrow--I was seeing temps in the high 50's at the top of
the fridge side; clearly unacceptable. I've since moved the probe more to
the middle--just atop the crisper drawers. Temp reading is in the low 40's
so it may be getting better if it continues to drop.

What was puzzling me when I first started noticing that something wasn't
right was that it was cycling off even though temps on the fridge side were
too high. Usually when I go through the dirty condensor routine I notice
it not shutting off before I notice the temp issues. Now it could just be
that it's the dirt issue once again and maybe I happened to notice it not
running when a defrost cycle happened to occur. But the idea of a blocked
cross passage from the freezer makes a lot of sense.
