Model # BI-30UG

Sub-Zero refrigerator repair

The BI-30UG is the glass-door version of the BI-30U, a 30″ Classic over-and-under refrigerator/freezer also printed as the BI-30UG/O.

Frost building up inside the freezer compartment and a cabinet that recovers slowly after the door has been held open are the issues reported most on a BI-30UG — both point back to how well the door is sealing. Condensation forming on the inside face of the glass door is the other common call, usually tied to the same seal or to the glass pane’s insulating performance after years of use.
