The Samsung RT18M6215SG is part of the Refrigerator
test program at Consumer Reports. In our lab tests, Top-freezer refrigerator
models like the RT18M6215SG 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.
Gallon storage on door
Gallon storage on doorDoor shelf can accommodate a standard one-gallon plastic milk container and makes for easier access to beverages.
Half shelfHalf shelves, typically found on top-freezer or bottom-freezer models, can be set at the same height to provide a full-width shelf or can be set to different heights to improve storing flexibility.
IcemakerTypically makes 3 to 4 pounds of ice a day--but according to our repair data, an icemaker may also add reliability problems. Some higher-end models have a feature to speed ice-making, which produces as much as twice the amount in the same time.
Water dispenserIt is normally located in the fresh food compartment.
Touchpad controlsIn some models, you can use an electronic touchpad to adjust the temperature settings. In some higher-end models, the display will show the actual temperature.
Uniquely adjustable shelves
Uniquely adjustable shelvesShelves that can be moved up and down without removing food. An example is a shelf that adjusts by rotating a crank handle.
Built-in water filter
Built-in water filterA water filter, included with many icemakers, is intended to reduce levels of lead, chlorine, and other impurities. A filter usually adds to the cost of the refrigerator, so have your tap water tested to see if you really need one. Change about every six months; filter-cartridge-replacement costs range from $30 to $40, plus shipping.
Child lock-out for dispenser
Child lock-out for dispenserThis feature, usually a button or switch, allows you to disable the ice and water dispensers. The icemaker continues to work while the dispensers are disabled.
Freezer lightAvailable on most models.
Stainless/SS-look optionStainless steel is stylish but it shows fingerprints. Another option: a vinyl-covered metal finish that gives you a stainless-steel look but resists smudging.
Spillproof shelvesShelf is designed to contain spills.
Exterior heightOur measurement, including the top hinge and rounded up to the nearest inch. (We measured only tested models, but the similar models we list should have the same dimensions.) Built-in models have the compressor on top, making them about a foot taller than regular refrigerators. They fit flush with cabinets and counters.
Exterior widthOur measurement, including all protrusions and rounded up to the nearest inch. (We measured only tested models, but the similar models we list should have the same dimensions.)
Exterior depthOur measurement, rounded up to the nearest inch. We include tubing or other protrusions in the back but exclude the handle. (We measured only tested models, but the similar models we list should have the same dimensions.)
Total usable capacity
Total usable capacityUsable capacity is the volume, in cubic feet, of usable interior space, based on our measurements. We included ice-makers in the storage measurements for top-freezer and bottom-freezer models, but not for side-by-sides.
Energy cost/yr.Estimated cost in dollars, based on the current year's average national electricity rate. Your cost will vary depending on the rate for electricity in your area.
Energy StarQualified by the U.S. government's Energy Star program for low power consumption.
CR's suggested refrigerator setting
CR's suggested refrigerator settingThis is the refrigerator section controller setting, typically in degrees but sometimes a numeric value used for our 70 degree ambient temperature test to get the refrigerator center to be between 36 and 38 degrees.
CR's suggested freezer setting
CR's suggested freezer settingThis is the freezer section controller setting, typically in degrees but sometimes a numeric value, used during our 70 degree ambient temperature tests to achieve a center temperature between -1 and 1 degrees. NA indicates that there is no separate freezer control.
