Model # IT-36R

Sub-Zero refrigerator repair

The IT-36R is a 36″ Designer over-and-under refrigerator, panel ready, from Sub-Zero’s legacy Designer generation. It’s no longer produced.

Condenser airflow restricted by dust at the grille, and a control panel reading a temperature the cabinet isn’t actually holding, are the issues reported most on an IT-36R. A custom panel that’s worked its way proud of the surrounding cabinetry after years of use is the other common call, worth checking alongside the condenser.
