Overview
The EdgeStar CRF321SS is a 3.1 cubic foot compact fridge and freezer with separate doors for each compartment and a true stainless steel front over a black cabinet.
It replaces EdgeStar's earlier CRF320SS with a different refrigerant for better energy efficiency, the main change between the two models.
- 3.1 cu ft fridge and freezer combo
- Separate doors, separate thermostats
- True stainless steel doors, black cabinet
- Slide-out shelves and molded worktop
Who it's for
Works for a dorm room, bedroom, or basement bar where a true separate freezer matters, not just extra fridge space. Not the right size for anyone needing to store more than snack-level food and a few days of groceries.
Pros and cons
- Freezer compartment freezes food solid, not just cold
- Runs quietly enough that the compressor is barely noticeable
- Reversible doors and door bins in both sections
- Ships heavily boxed and padded for damage-free arrival
- 3.1 cubic feet limits it to light, single-person use
- Coldest fridge setting may run warmer than the spec suggests
- Manual defrost required on the freezer side
Performance notes
One reviewer flagged a gap between the listed maximum fridge temperature of around 60F and what the control knob's warmest setting actually produced, which topped out closer to 41-44F in their unit, worth knowing if you need the fridge for higher-temperature storage rather than typical food cooling.

Frequently asked questions
Does the EdgeStar CRF321SS have a separate freezer door?
