The Frigidaire FFFH21F6QW is part of the Freezer
test program at Consumer Reports. In our lab tests, Freezer
models like the FFFH21F6QW are rated on multiple criteria, such as those listed below.
Thermostat control: This assesses the ability of the refrigerator's thermostat to 1) achieve the desired initial set temperatures following manufacturer's recommendations 2) achieve optimum temperatures in both the fresh food and freezer sections simultaneously and 3) 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 its fresh food and freezer sections.
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.
Controls on front of unit
Controls on front of unitIndicates that controls are located on the front of the unit.
Power on light
Power on lightIndicates that model has light to show the freezer is powered on.
Temperature alarmThe freezer will sound an audible alarm if the temperature rises above a manufacturer's preset temperature.
Compressor run light
Compressor run lightA light that alerts the consumer when the compressor is running.
Door lockHas a door lock which allows the user to lock its contents.
Interior lightHas interior light inside the freezer's compartment.
LED interior light/s
LED interior light/sHas an LED interior light inside the freezer's compartment.
Tiered binsThis feature only applies to chest freezers. It indicates that the model has tiered bins which allow for better organization of the freezer contents.
Compartment dividersThis feature applies to chest freezers only. It indicates that the model has upright plastic dividers that allow the user to compartmentalize their stored items for better organization.
Quick freezeThis feature allows users to call for max cooling in the event they have recently stocked the freezer with newly purchased unfrozen items.
Soft freeze compartment
Soft freeze compartmentA separate section of the freezer, usually enclosed with a door, that allows for the storage of flavored ices and/or ice cream for easier consumption.
Claimed capacityClaimed capacity is the manufacturer's estimate of the volume, in cubic feet, of interior storage space.
Usable capacityUsable capacity is the usable storage space based on our measurements, and excludes the corner spaces for models with rotating turntables. Note that most Over-The-Range models allow you to turn the rotation off to fit large dishes (a few countertop models offer this feature, as well.) With the rotation off, measured capacity approximates claimed. However, food may require extra tending and stirring.
