Whirlpool WRS321SDHZ Refrigerator

Stainless steel is stylish but it shows fingerprints. Another option: a vinyl-covered metal finish that gives you a stainless-steel look but resists smudging.

The water dispenser is normally accessible from the outside as part of the ice and water dispenser.

Through-the-door ice and water dispensers usually offer cubed or crushed ice and filtered water, but are only available on French-door models, with a special compartment in the fresh food section. They add significantly to the purchase price--and according to our repair data, may also add reliability problems.

Typically 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.

A 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.

This 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.

Shelves that can be moved up and down without removing food. An example is a shelf that adjusts by rotating a crank handle.

Half 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. Split shelves, found on some side-by-sides, allow one side either to fold under the back half, fold up and out of the way, or move right to left. This leaves extra headroom for tall items.

Shelf is designed to contain spills.

Door shelf can accommodate a standard one-gallon plastic milk container and makes for easier access to beverages.

Available on most models.

In 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.

The refrigerator can connect to the WiFi in your home.

Our 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.

Our 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.)

Our 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.)

Usable 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.

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.

Refrigerators manufactured after April 28, 2008, earning this designation must be at least 20 percent more energy efficient than the minimum federal standard.

This 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.

This 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.
