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
The hardest water in the Bay Area
Contra Costa Water District delivers around 7.2 grains per gallon in Concord, several times EBMUD's supply, and a valve held off its seat by deposit weeps continuously.
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.
