ups.com...I was wondering if anyone knows why the "old fashioned" back mounted
coil refrigerators were replaced with bottom mounted coils?

Back coil mounts didn't become as filthy nor did they need a fan to
blow air over them.

Just curious...

TIA!

I suspect it was when self-defrosting units came to be. They need some place
to drain the water. The heat from the coils along with the fan works to
evaporate the water from the drain pan so you don't need a drain through the
floor.

They made self-defrosting units for a long time with coils in the
back. The one I have now from mid 80s is made that way and I know
they were made in the 70's with auto defrost and coils too. Not sure
when the non-exposed coil units first appearerd, but I would guess
90's?

Definitely better, as you don't have to worry about the exposed coils
in back when moving it and it goes back close to flush.
