The Maytag MRT711BZDM is part of the Refrigerator test program at Consumer Reports. In our lab tests, Top-freezer refrigerator models like the MRT711BZDM 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 refrigerators with the same energy cost per year may have different energy efficiencies — the unit with more storage space being more efficient.
