    Test Results

    Thermostat control

    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

    Temperature uniformity

    This performance test is based on how well a model minimizes warm and cold spots within its fresh food and freezer sections.

     /  5
    Energy efficiency

    Energy efficiency

    This reflects electricity consumption per cubic foot of measured usable storage space. For example, two models with the same energy cost per year may have different energy efficiencies -- the unit with more storage space being more efficient.

    Noise

    Noise

    Noise level was measured when the compressor started up and during steady running. Subjective judgments by a panel of listeners supplemented our noise-meter readings.
