Overview
The Kenmore KKUF21-W is a 21 cubic foot upright unit that converts between refrigerator and freezer modes, with 4 repositionable shelves, auto defrost and a digital control panel for garage or basement storage.
Its main selling point is flexibility. A single dial switches the whole cabinet between fridge and freezer temperatures, so it can double as overflow drink storage in summer and bulk meat storage in winter. Reviewers confirm it holds temperature reliably, though its size makes it worth measuring your garage or basement space before buying.

- EnergyStar certified, 2 year warranty
Who it's for
Suits households wanting one large capacity unit for a garage, basement or dorm that can shift between chilling drinks and freezing bulk food. Anyone with limited floor space should check dimensions first, since a couple of reviewers found it larger than expected for the intended spot.
