Sub-Zero CL3050U

Model # CL3050U

Sub-Zero refrigerator repair

The CL3050U is a current-production 30″ Classic over-and-under refrigerator/freezer — 84″ high, 16.9 cu. ft. total volume, with a bottom-mounted freezer and automatic ice maker, built in, and running on R-600a refrigerant. Because it’s still in production, parts and service documentation are more current than on the legacy Classic series.

New fan noise from behind the rear panel, and a cabinet that holds temperature overnight but drifts warmer through the day, are the cooling issues reported most on a CL3050U. Separately, the ice maker producing no ice, slow ice, or cloudy cubes is a common call worth checking on its own.
