I was kind of hoping you would reply back as I’m trying to help you.
Like many things in life I know just enough to be dangerous! :laugh: – but I believe the moisture removal is part of the compressor function with a heater that captures the moist air and actually some heat “burns off” the moisture. I wonder now if that exchanger which dissipates on the outside of the unit is blocked somehow in your new refrig. The term is Frost Free nowadays and in the old units the moisture would stay inside and turn to frost, which would continue to build up into solid layers of ice.
