Bill, the fan in the RM182B is rated at 0.7 watts, or 58 milliamps.  That's
also what mine measured several years ago.  That would cut the consumption
down to just under 1.5 amp-hours per 24 hours, or about 10 amp-hours per
week, run continuously (3 1/3 AH at 8 hours/day).  If yours is actually
drawing 220 ma, I wonder if it's jammed or internally shorted, or not the
original fan.  Mine croaked, btw, and I just replaced it with a Fridgemate
fan that draws about 90 ma (and pumps more air).  200+ ma would be about
right for a computer power-supply fan or similar...

Are you sure?  I don't have any specific knowledge, but that fan is set to
come on when the ammonia-vapor cooling fins hit 140 degrees F. at the
outside of the topmost fin (so the vapor would actually be quite a bit
hotter than that, as the fins have a surprisingly small contact with the
vapor tube).  Disabling the fan will certainly make the refrigerator
perform badly, but might it also damage the cooling system?  I'm guessing
it will not, but I have enough doubt to not want to risk it.
