Sub-Zero DET3650CI

Model # DET3650CI

Sub-Zero refrigerator repair

The DET3650CI is a current-production 36″ Designer over-and-under refrigerator/freezer with an ice maker, panel ready — the same platform as the DET3650C.

A compressor running noticeably longer than it used to, and a control panel reading a temperature the cabinet isn’t actually holding, are the cooling issues reported most on a DET3650CI. When the ice maker turns out no ice, slow ice, or cloudy cubes, that’s usually its own issue rather than a sign of a bigger cooling problem.
