The EdgeStar CRF321SS is the best-supported choice for shoppers who want a compact refrigerator with a separate freezer: ENERGY STAR lists 3.1 cu. ft. of capacity and annual energy use of 270 kWh. For a much smaller appliance that can switch between refrigerator and freezer modes, consider the CRF150SS-1, whose manual specifies 1.1 cu. ft. Neither model is established here as a tested winner, and these specifications are not a complete or definitive EdgeStar lineup.
Which EdgeStar mini fridge fits your space?
Start with how you will use the appliance. The CRF321SS offers more capacity and a refrigerator/freezer configuration. The CRF150SS-1 is substantially smaller and convertible: its manual describes refrigerator and freezer operating modes, rather than a separate fridge and freezer compartment.
| Model | Capacity and configuration | Dimensions | Energy information | Placement and availability |
|---|---|---|---|---|
| EdgeStar CRF321SS | 3.1 cu. ft.; ENERGY STAR classifies it as a compact refrigerator. Lowe’s lists it as a mini fridge with freezer. ENERGY STAR; Lowe’s | ENERGY STAR lists 33.0 in. high × 18.5 in. wide. Lowe’s lists 18.7 in. wide × 19.9 in. deep × 33.4 in. high. The sources give different measurements; check the current manual and the unit before planning a fit. ENERGY STAR; Lowe’s | 270 kWh/year, as reported by ENERGY STAR in its 2026 product record, captured March 3, 2026. ENERGY STAR | ENERGY STAR records a U.S. market-availability date of July 7, 2025. That date does not confirm current stock or price. ENERGY STAR |
| EdgeStar CRF150SS-1 | 1.1 cu. ft.; convertible refrigerator or freezer, according to the owner’s manual. Owner’s manual | 19 5/16 in. high × 18 11/16 in. wide × 17 1/8 in. deep, per the manual; confirm the appliance’s rating label and installation measurements.

EdgeStar CRF321SS: the larger option with a freezer
The CRF321SS is the clearer fit when you need both refrigerated storage and a freezer in one compact appliance. ENERGY STAR classifies it as a compact refrigerator and lists automatic defrost, 3.1 cu. ft. capacity, no ice maker, and no through-the-door dispenser. Its 270 kWh/year figure is an ENERGY STAR record value, not a promise of an individual household’s consumption; actual use can depend on conditions and operation.
Measure the space carefully. ENERGY STAR lists the CRF321SS at 33.0 inches high and 18.5 inches wide, while Lowe’s lists 18.7 inches wide, 19.9 inches deep, and 33.4 inches high. These are source-specific listing measurements, not interchangeable installation specifications. Check the current manual for clearance and ventilation requirements, and compare those with the location’s usable dimensions before purchase.

EdgeStar CRF150SS-1: smaller, with a convertible mode
The CRF150SS-1 manual describes a 1.1-cu.-ft. appliance that operates either as a refrigerator or as a freezer. Its specified temperature range is 32°F–50°F in refrigerator mode and 5°F to −11.2°F in freezer mode. Those ranges describe the manual’s operating modes; they do not mean the unit provides separate refrigerator and freezer compartments at once.
The manual gives dimensions of 19 5/16 × 18 11/16 × 17 1/8 inches (height × width × depth), says the appliance is intended for domestic indoor use, and notes that specifications may change. It directs users to the rating label for the most accurate technical information. Lowe’s listing identifies model CRF150SS-1 but calls the product a freezerless refrigerator, so confirm the exact SKU and configuration with the seller before relying on the manual’s convertible specifications.

How to choose and verify before ordering
- Choose the storage arrangement. Pick the CRF321SS if the separate freezer arrangement and greater listed capacity suit your needs. Consider the CRF150SS-1 if minimizing appliance size matters more and you can use one operating mode at a time.
- Measure the installation space. Check width, depth, height, door swing, and any ventilation or clearance requirements in the current manual. Do not assume the retailer’s and certification record’s CRF321SS dimensions match exactly.
- Confirm the model and configuration. Match the model number on the seller’s page and product label to the documentation, especially for the CRF150SS-1 listing.
- Check current terms directly with the seller. The cited listings do not establish current price, stock, shipping, or return terms. Verify those details before placing an order.
What the available specifications cannot tell you
The cited records and manual establish selected capacity, dimensions, configuration, and energy information, but they do not provide an independent comparison of cooling consistency, noise, reliability, or value. Treat this as a model-specific specification guide, not a hands-on performance ranking. Nor do these sources establish every EdgeStar mini refrigerator currently offered.
