Model # 650G

Sub-Zero refrigerator repair

The 650G is a built-in over-and-under refrigerator/freezer from the 600 Series with a glass door, front venting, a lighted electronic control panel, and adjustable spill-proof glass shelves.

A control panel reading a temperature the cabinet isn’t actually holding is one of the more common issues on a 650G, often traced back to a sensor rather than the compressor itself. Fan noise from behind the rear panel that wasn’t there before, and condensation forming on the inside face of the glass door, are the other issues typical of this model.

FAQ

Sub-Zero 650G FAQ

A mismatched panel reading is usually a sensor issue rather than a sign the cabinet has actually lost its cooling — worth confirming with a thermometer before a repair visit.

Occasional condensation is normal, but if it’s persistent, it’s usually tied to the door seal or the glass pane’s insulation.
