Overview
Whynter's UDF-139SS is a 13.8 cubic foot upright that converts between freezer and refrigerator with a button press. Freezer mode reaches -11F on the Quick Freeze setting, and refrigerator mode holds a 35F to 46F band, all shown on an LED display.
What buyers usually come here for is the frost free design. Air circulation prevents the ice sheet that builds on a manual defrost box, so drawers keep sliding and packages do not weld themselves to the shelf. It is Energy Star rated, runs on R600a at 42dB or below, and rolls on built in casters so a full unit can still be nudged aside for cleaning.
- 13.8 cu ft convertible upright
- Quick Freeze drops interior to -11F
- Fridge mode range 35F to 46F
- 4 sliding shelves, 4 door shelves, wire basket
Who it's for
Aimed at people adding serious cold storage to a garage, basement or small commercial space, and at anyone who might want fridge capacity one year and freezer capacity the next. If you only need a few cubic feet, this is far more machine than the job calls for.
Pros and cons
- Switches between freezer and fridge duty
- Frost free, no annual defrost chore
- Energy Star rated with door alarm
- Casters make a loaded unit movable
- One temperature for the whole cabinet
- Arrives dented often enough to expect it
- Needs real floor space at 13.8 cu ft
- Door seal strength varies unit to unit
Performance notes
Convertible operation is a thermostat range rather than a separate compartment, so the whole cabinet sits at one temperature. Four sliding cabinet shelves, four door shelves and a wire basket are what make fridge mode practical instead of a novelty. The open door alarm and lock button matter more than they sound on a garage unit, where a door left ajar is not something you notice for hours.

Frequently asked questions
Does the Whynter UDF-139SS need manual defrosting?
No. It uses a frost free design, and owners specifically credit that with removing the every other month defrost routine.
How cold does the Whynter UDF-139SS get in freezer mode?
The Quick Freeze function drives the interior to about -11F, colder than a typical freezer setting.
Can the Whynter UDF-139SS run as a refrigerator only?
Yes. A button switches it to a 35F to 46F range, though the entire cabinet changes together rather than splitting into two zones.
