Model # IT-36CI

Sub-Zero refrigerator repair

The IT-36CI is a 36″ Designer over-and-under refrigerator/freezer with an ice maker, panel ready, from Sub-Zero’s legacy Designer generation. It’s no longer produced.

A compressor running noticeably longer than it used to, and frost building up inside the freezer compartment, are the cooling issues reported most on an IT-36CI. Separately, the ice maker producing no ice, slow ice, or cloudy cubes is a common call worth treating as its own issue rather than assuming it’s tied to the main cooling system.
