The BI-36R is a 36″ Classic all-refrigerator from Sub-Zero’s legacy built-in lineup, with no freezer section, also printed as the BI-36R/S and BI-36R/O.
A door that no longer pulls fully closed onto its gasket is the issue reported most on a BI-36R, and it can lead directly to a cabinet that holds temperature overnight but drifts warmer through the day. A unit running constantly without ever settling into a normal cycle is the other common call, which points to the compressor struggling to reach its set point rather than just working hard.
