The BI-48S is a 48″ Classic side-by-side refrigerator/freezer from Sub-Zero’s legacy built-in lineup, without a dispenser.
A cabinet that holds temperature overnight but drifts warmer through the day, and a control panel reading a temperature the cabinet isn’t actually holding, are the issues reported most on a BI-48S. Condenser airflow restricted by dust at the grille is the other common call, and it’s worth checking before assuming the compressor itself is failing.
