The CL3650UG is the glass-door version of Sub-Zero’s current-production 36″ Classic over-and-under refrigerator/freezer, with parts and service documentation kept current since it’s still in production.
A door that no longer pulls fully closed onto its gasket is the issue reported most on a CL3650UG, and it can also explain a control panel reading a temperature the cabinet isn’t actually holding. Condensation forming on the inside face of the glass door is the other common call, usually tied to that same door seal or to the glass pane’s insulating performance.
