Question about Sub-Zero 650 / O Bottom Freezer Refrigerator
My 550 is about 12 years old and when the weather gets warm and humid, frost starts to build up on the inside of the refrigerator on the back side behind the veggie drawer (left side). The temp starts to climb up, but, still maintains temp around 40 to 43F. I have checked the door seals and they appears to be okay, but, since this only happens when the humidity increases in the home, maybe the door seals needs to be replaced? I vacuum clean the condenser coil, fan & blade, compressors, and all the parts in the area equipment area twice a year. Do you have any suggestions on the cause? Also, where can a person get a copy of the service manual for this unit?
This means you are low on freon. You will get an ice ball on the bottom left side in the back of refer.

I had the same problem. It is NOT freon. Got to the point that ice would build up every few days. Talked to Subzero, they said insulation is breaking down between freezer and refrigerator (my unit is 21 years old and otherwise great). I ordered a part from them for $150 that you install in the drain tube that keeps it thawed. My husband and I were able to replace it ourselves. It was time-consuming, but has keep us ice-free for several months. Cheap fix to keep unit around without replacing. Read direction carefully. You have to remove all shelves from the inside the refrigerator, covers, to expose the coils, and have access to wiring from thermostat, light, etc. They give you all necessary parts including wiring harnesses, etc. Everything can be done inside the food area of the refrigerator. Be patient. It will all come together and was money and time well spent.
