The BI-30U is a 30″ Classic over-and-under refrigerator/freezer from Sub-Zero’s legacy built-in lineup, also printed as the BI-30U/S and BI-30U/O — suffixes whose meaning isn’t documented anywhere we could confirm.
A compressor running noticeably longer than it used to is the issue we hear about most on a BI-30U, and it’s often connected to a door that no longer pulls fully closed onto its gasket. A control panel reading a temperature the cabinet isn’t actually holding is the other common call, and checking the door seal first is usually the fastest way to rule out the simplest cause.
