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.
