Whirlpool WRT318FZDB Refrigerator Review
This affordable fridge is worth every penny.
There are several variations of the Whirlpool WRT318FZDB. These include the Whirlpool WRT318FZDM and Whirlpool WRT318FZDW. They are very similar to the Whirlpool WRT318FZDB in most respects.
The Cold Hard Facts
While it’s not perfect, the Whirlpool WRT318FZDB (MSRP $749) stands head and shoulders above most similarly priced 18-cu.-ft. top freezers. For $550 retail, you get remarkably low energy consumption and on-point average temperatures. Just don’t put a lot of faith in those crispers.
Despite the thermostat’s lack of options, the recommended setting for the main fridge section turned out to be more or less fine. We recorded average temperatures of 35.83°F at the top, 35.24°F in the middle, and 37.75°F down at the bottom. While 35°F is a little cold for fresh food storage, at least the fridge doesn't run too warm. We tracked an average temperature fluctuation of just ±0.41°F over time.
The freezer is somewhat less stable: The upper shelf averaged -2.22°F, but the lower section clocked in at 1.53°F. There’s not a lot you can do to bridge the gap, but turning the freezer’s control knob down should at least get the whole compartment below 0°F.
Of course, the colder a freezer is, the less stable it usually becomes: Upper shelf temperatures fluctuated by about ±1.16°F over time—not enough to bring it above 0°F and accelerate freezer burn. The lower shelf only shifted by ±0.33°F.
Without question, this Whirlpool’s crisper drawers are its greatest weaknesses. Over the course of three days, our test materials lost an average of 0.31 grams of moisture each hour. That’s about three times worse than average, and could lead to faster spoilage of produce.
For a inexpensive top freezer, this Whirlpool was actually pretty speedy when it came to chilling. Our room-temperature sensors were brought down to 32°F in just 1 hour 24 minutes. We’ve seen faster, but most top freezers take about 10 more minutes.
Storage Space & Energy Efficiency
At an advertised 18-cu.-ft., this Whirlpool isn’t big, but it does make the most of its space. In the main fridge section, the combination of shelves, drawers, and door storage combine to give you 10.84 usable cubic feet of storage.
The simple freezer compartment offers 4.12 usable cubic feet spread across its two shelves and door storage. That's quite impressive for a fridge in this class.
Even more impressive is this fridge’s energy efficiency. It only takes 0.04 kWh to cool each usable cubic foot, making this one of the most efficient fridges we've ever tested. Assuming typical electricity costs and use patterns, that works out to roughly $21.92 a year—less than the price of a nice dinner.
