The Frigidaire
FFUF2021AW is part of the
Freezers test program at
Consumer Reports. In our lab tests, Upright Freezers
models like the FFUF2021AW are rated on multiple criteria, such as those
listed below.
Thermostat control
This assesses the ability of the Freezer's thermostat to 1) achieve the desired initial set temperatures following manufacturer's recommendations. 2) keep internal temperatures constant despite large changes in room temperature.
Temperature uniformity
This performance test is based on how well a model minimizes warm and cold spots within the freezer.
Energy efficiency
This reflects electricity consumption (based on our tests) per cubic foot of measured usable storage space. For example, two freezers with the same energy cost per year may have different energy efficiencies -- the unit with more storage space being more efficient.
