Amen! The only way I can figure how to clean the coils underneath the frig is
tape a plastic garbage bag on the front of frig, take back off, and drag my air
hose from garage into kitchen and blow the dust out. Garbage bag traps most of
dust but not all and cleaning the blade on blower is a pain too. Like to have
the old ones with coil on back.

I just bought one with coils on the back. It is a small hotel sized one (not the mini dorm size, but just slightly under 18 cu ft.) I was very careful moving it, those coils run the full height of the fridge and look very fragile.

You nailed it! Under-side coils are impossible to get very clean. And, as they
clog-up with dust, the condenser temps go up, which means the compressor
pressures go way up, shortening the compressor life. The old-style rear
condenser units are WAY more reliable. I've seen them run 40+ years.
It might be true that the fan-cooled coils are more efficient, but that
efficiency will be gone within a month in most households where the coils will
quickly get covered with dust.

I bought a medium size Estate (Whirlpool) top freezer model fridge 2
years ago for beer, pop, and bottled water and the condenser coil is on
the back. I think it's around 15 Cu Ft or so. I'm not sure and this is
just conjecture but where a larger fridge say 25 Cu Ft needs higher
capacity, performance is increased with a forced air condenser. Also makes
sense about blowing warm air over the defrost pan as another mentioned.
My theory: look at the volume occupied by a rear-mounted condenser with
the appropriate amount of air space behind the fridge (and above it as
well). That's a lot of volume that isn't storing anything cold. By
using a fan-cooled condenser, the refrigerator case can be about 3
inches deeper and a couple inches higher and still fit into the same
space without projecting any further into the room. That gives a
significant increase in inside room if the box insulation remains the
same thickness, or allows thicker insulation (for better efficiency)
while keeping the interior volume the same.
