Model # DET3650R

Sub-Zero refrigerator repair

The DET3650R is a current-production 36″ Designer over-and-under refrigerator, panel ready and freezerless — a single-door, 20.4 cu. ft. cabinet with no freezer section.

A cabinet that recovers slowly after the door has been held open is the issue reported most on a DET3650R, and it can also show up as accumulated cold-storage frost in humid conditions. A custom panel that’s worked its way proud of the surrounding cabinetry after years of use is the other common call on this panel-ready model.

Correct — there’s no freezer section on this model, just a freezerless, single-door cabinet.
