In black stainless, the B36CT80SNB is the dual-compressor edition of the 800 Series counter-depth French door. Households choose it for the finish and for how well it keeps food, since the two cooling halves work separately and moist refrigerator air never mixes with the dry air of the freezer.
The architecture is the thing to understand. A separate compressor and evaporator serve each section, which preserves food better and also means one half can stop completely while the other stays untouched. That is a clue, not a coincidence: it tells a technician which circuit to investigate and spares a full-system teardown.
Two other points come up on visits. The black stainless coating marks permanently under magnets and abrasive cleaners. And ice output is lower than on single-compressor models, which owners sometimes read as a failing ice maker. We check it against the spec sheet; if it is making what the design is meant to make, nothing needs fixing.
Seldom. Every section is cooled by its own compressor, evaporator and fan, so trouble on one side points us toward a single circuit. A narrower diagnosis usually means a narrower repair.
The published rating for the dual-compressor 800 Series is a smaller daily ice output than its single-compressor siblings produce. If yours matches the spec sheet, it is working as designed, and we can confirm that on a visit.
Each section cools independently, so humid refrigerator air and dry freezer air stay separate. Food in the fresh food compartment is less likely to dry out.
