LG LDG4315ST Double Oven Gas Range Review
Sure, new tech is cool, but it's the uniform cooking and quick preheat we really love.
From the Lab
We tested the LG LDG4315ST extensively in our labs, recording everything from preheat times to rangetop temperatures. Our findings were mixed, with this range exceeding expectations in some areas and underperforming in others.
In our oven testing, we bake a sheet of cookies and then two cakes side by side. When the food is ready, we use a photospectrometer to measure any variation in doneness that may indicate temperature regulation issues in the cavity.
Unfortunately, neither oven treated our cakes or cookies particularly well when we used standard bake settings. The lower oven, equipped with ProBake, turned out two cakes that were browned differently depending on their location in the cavity. Each individual cookie was evenly browned, but results varied across the sheet.
The upper oven was much worse. Cakes were completely varied in browning, and cookies weren’t much better.
The lower oven was much improved by the use of the convection setting, but there’s no saving the upper oven, which lacks convection. The lower oven earned itself near-perfect scores when we tried baking cakes and cookies with convection, so make sure to use this setting if you decide to take this range home.
Preheats were astoundingly fast in the lower oven, which took just 4 minutes 18 seconds to preheat for standard baking, and 5 minutes 34 seconds for convection. By contrast, the upper oven, which should’ve preheated more quickly due to its small size, took more than 8 minutes to finish preheating.
The rangetop made it through most of our tests with flying colors. You’ll want to save the two front burners for high-heat cooking and boiling, which both scored particularly well. The right front burner maxes out at 427°F and takes just 3 minutes 42 seconds to boil 6 cups of water. The left front burner is almost as hot, hitting a maximum temperature of 414°F and boiling in 5 minutes 43 seconds. Both are pretty good at dipping to low temperatures as well, reaching their minimum temperatures at 143°F and 146°F, respectively.
However, the rear of the rangetop should be the most effective at simmering and other low-heat tasks. The right rear burner has a minimum temperature of 117°F, the lowest on the rangetop—but unfortunately that’s the only thing it does well, with a maximum temperature below 300°F and an unreasonably long boiling time. At least plenty of this rangetop’s burners are better at multitasking, for example the left rear burner gets almost as mild at 138°F, climbs to almost 400°F at its hottest, and boils in 9 minutes 50 seconds. Not bad.
The oval center burner can’t drop below 150°F, but otherwise scored similarly to the left rear burner.
