Sub-Zero Seal System Leak Freon Leak
Seal System Leak Freon Leak is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
A water line that had to be run the long way
The radiant heating loop is cast into the slab, so supply lines go overhead or around the perimeter; the extra joints in that run are where leaks start.
A clogged defrost drain
Melted frost backs up and overflows into the cabinet or onto the floor instead of draining away normally.
A worn or torn door gasket
Lets humid air in that condenses inside the cabinet or around the door frame.
