Model # BI-36UG

Sub-Zero refrigerator repair

The BI-36UG is the glass-door version of the BI-36U, a 36″ Classic over-and-under refrigerator/freezer also printed as the BI-36UG/S.

Interior lighting that stays dark, or flickers as the door opens, is a common complaint on a BI-36UG, usually a bulb or socket issue rather than anything refrigeration-related. A cabinet that recovers slowly after the door has been held open, and condensation forming on the inside face of the glass door, are the other calls typical of this model, both tied to how well the door is sealing.

FAQ

Sub-Zero BI-36UG FAQ

Check the bulb and socket connection first; that’s the most common cause on this model.

That’s usually the door seal or the glass pane’s insulation losing effectiveness with age.
