Update -- Tried the fridge on 120VAC and it worked well.  Filled the
propane tank, and though the fridge lights & works on propane, it is
winter so I suspect it's just barely working.  The flame, which
normally looks uniform and blue through the viewing glass, has a
clear glowing red portion.  Also, the amount of heat escaping the
flue is much less than normal.    So it seems like I have a clogged
jet and/or combustion chamber.  I'll pull it and clean it today.

So I think to answer my original question -- No, it appears as if the
fridge is not particularly sensitive to low LPG level.  If the stove
burners work, the fridge flame should too.
