Model # DET3650C

Sub-Zero refrigerator repair

The DET3650C is a current-production 36″ Designer over-and-under refrigerator/freezer with an ice maker, panel ready — 84″ high, 19.6 cu. ft. with a bottom freezer.

A cabinet that holds temperature overnight but drifts warmer through the day, and new fan noise from behind the rear panel, are the cooling issues reported most on a DET3650C. The ice maker itself often needs a separate look when it’s making no ice, slow ice, or cloudy cubes.

FAQ

Sub-Zero DET3650C FAQ

Minor swings through the day are normal; a persistent pattern is the one worth checking, beginning with the door seal.

It’s seldom the refrigeration system — cloudy cubes more often trace back to water quality or the filter.
