Sub-Zero BI-36UID

Model # BI-36UID

Sub-Zero refrigerator repair

The BI-36UID is a 36″ Classic over-and-under refrigerator/freezer with an internal dispenser, also printed as the BI-36UID/O.

A control panel reading a temperature the cabinet isn’t actually holding, and a cabinet that holds temperature overnight but drifts warmer through the day, are the cooling issues reported most on a BI-36UID. Separately, the internal dispenser delivering no water, or delivering it slowly, is a common call that usually traces back to the fill valve or supply line rather than the refrigeration system itself.
