Mine is a through the door despenser. As we probably use about 4 glasses of
ice a day, it does not get used very much. The come out the bottom, so stay
about the same size. The ones near the top back side tend to melt and stick
together, maybe during the defrost cycle, but not sure why. Then the lump
is too big to make it out the door.

Possibly humidity? I.e., it is very dry here, most of the year.
The MANUAL DEFROST freezer chest in the garage rarely *needs*
to be defrosted -- until our "rainy season" (Monsoon). Then,
the humidity (though usually only ~60%) climbs enough that
we notice a rapid buildup of ice along the interior of the
freezer necessitating a defrost cycle (at the end of Monsoon).

I suspect the low humidity is also the reason that "old" ice
cubes tend to shrink -- sublimating so there is no "clumping"
formation.
