Consistent cooling power
We spend weeks testing each refrigerator we review in a climate-controlled chamber where we can take a cold, hard look at performance. The LFXS32726S came through with flying colors -- namely, all of the shades of blue in that heat map up above.
With zero hot spots in any of our tests and accurate, generally consistent temperatures throughout the entirety of the fridge, it's hard to imagine how the LFXS32726S could have done much better. Crunch the numbers, and you'll see that both the body of the fridge and the two doors average out to 36.7 degrees at the 37-degree setting. That's a bull's-eye, as far as iceboxes are concerned.
Those results aren't without a few notable quirks. Take a look at the green lines in that color-coded, minute-by-minute graph of that same 37-degree test. Those are the shelves in the left door -- the coldest section of the fridge, overall. That's a big surprise, as the door shelves in refrigerators -- even ones with in-door ice makers, like this one -- typically run warmer than the body of the fridge.
And sure, it's tough to fault a fridge that does too good a job of keeping things cold, but it's worth noting that the pattern persists at lower temperature settings. At the fridge's lowest setting, those left door shelves spent much of the 72-hour test below freezing.
I was also surprised to see that the butter bin -- typically the warmest section of the fridge by design -- was actually colder than the rest of the shelves in the right door. If you like your butter soft and spreadable, you'd actually be better off keeping it in the right door's bottom shelf.
My only other performance qualm lies with that Glide N' Serve drawer I mentioned earlier. You can dial it between three presets ("Meat," "Deli" and "Produce") and presumably, the temperature changes with each one. My tests showed otherwise, though, with little more than a 1-degree difference among the three of them. Unless there's something going on with the humidity that I'm missing, those presets don't do much for the drawer other than label what you're storing inside.
For a closer look at the cooling test results, including a look at how the fridge fared when we dialed the temperature down to its minimum setting of 33 degrees F, check out our product gallery.
The LG LFXS32726S is one of the top-performing fridges we've tested, and the interior is built to take full advantage of the massive amount of storage space it offers. If capacity and cooling performance are key concerns in your kitchen, then it's a worthy upgrade.
That said, I'd be reluctant to spend more than $3,000 on a fridge that didn't offer any truly notable features or an especially good-looking design. Shop around, and you'll find plenty of simple refrigerators that perform almost as well and cost a lot less. That makes the LFXS32726S a stretch at its full retail price of $3,600 -- but if you catch it on sale, I say go for it.
