This oven won't burn your cookies


The LG LRG4115ST (MSRP $1,599.99) is an otherwise-nondescript freestanding five-burner gas range that happens to include one of the most exciting cooking innovations we’ve seen. Housed in the 6.3 cu.-ft. cavity is LG’s new ProBake system, which ditches the standard bottom-mounted heating element and instead relies entirely on a high-powered, true convection heating element at the back of the cavity.

If all this new tech sounds intimidating, don’t be scared off. Professional ranges in restaurant kitchens use similar technology, and our tests show the LRG4115ST is an excellent choice for the home cook, as well. Our time spent baking, broiling, and boiling with the new LG cemented that opinion. Our baked goods were evenly browned after a short preheat, and our water reached a rolling boil in a snap.

Until now, we’ve never had any strong opinions about LG’s lineup of gas ranges. But we can confidently say the new ProBake-equipped LRG4115ST is worth checking out.

Design & Usability

Minor cosmetic updates, but a major overhaul inside

The grates can be removed for easy cleaning.

In terms of design, LG played things safe this time. The LRG4115ST’s looks are unremarkable, with little deviation from established design language. Stainless steel abounds and we love the hefty oven door handle and bulky burner dials that are angled toward the user.

While its looks are pretty average, the LRG4115ST does feature a number of tweaks and touches to make cooking more enjoyable. Continuous cast-iron grates make moving heavy pots between burners a simple task, and standard pyrolytic self-clean and rapid steam clean options let you choose the cleaning mode that works for you. The steam clean mode is quicker, but encrusted grime requires you burn off the mess.

The LRG4115ST’s most exciting innovation is inside the cavity. The aforementioned ProBake system is a radical new cooking technology that puts a new spin on an old idea.

Most gas convection ranges turn off an oven’s main heating element when the convection fan spins, relying instead on a small electric heater to keep the oven warm. ProBake dispenses with a lower heating element entirely. Instead, there’s a high-powered gas burner at the rear of the cavity, and it’s embedded into a powerful fan.

LG says the new design makes for even heating, easier cleaning, and more space—6.3 cu. ft. to be exact. It was up to us to find out.

Rangetop

Gets the job done

LG not only put a lot of effort into the oven, but also redesigned the rangetop. Engineers angled the edges of the burner caps so gas flames could better reach the bottoms of pans.

Despite the promise of better performance, we were skeptical. We tend to temper our expectations for gas burners, which are more responsive but lack the range of temperatures and fast boiling speeds of electric and induction. Yet the LG LRG4115ST did have one remarkably fast burner, and an impressive temperature range.

If you want to boil up some water for a pasta or blanch some vegetables, your first choice should be the front right burner, which can do it in just four minutes. That’s an incredible result for any burner, let alone a gas one.

The LG LRG4115ST comes with an oval griddle, perfect for breakfast.

Maximum temperatures were on the cool side. The front right burner reached a maximum temperature of 442°F, while the remaining burners peaked between 420°F and 272°F. Fortunately, minimum temperatures were adequate for simmering or melting. The right rear burner dipped down to 110°F, while the remaining burners bottomed out between 127°F and 166°F.

Oven, Broiler, & Convection

Bakers, know thy recipes

As mentioned, the LG LRG4115ST’s cavity is unlike any other. Most ovens are heated from below by a gas or electric element. The LRG4115ST eliminates the bottom heating element entirely, and instead relies solely on a high-powered rear-mounted true convection element.

The ProBake system rewrites the rulebook.

Burnt cake and cookie bottoms—unavoidable with many ovens—were completely absent in our convection tests. This was confirmed by our standard bake tests: Not a single cookie emerged with a burnt bottom, and the cakes also scored well.

As promised, baked goods were more evenly cooked throughout. But we also found that placing thinner items—like cookies—anywhere near the rear element would result in burnt food. You’ll want to drastically adjust your cooking times or temperatures if you plan to whip up a batch of Grandma’s famous oatmeal raisin crisp. Cakes, on the other hand, fared better with ProBake than in a traditional oven.

The gas broiler took 8 minutes to reach target temperature.

The efficiency of the rear heating element, combined with what must be a well-insulated cavity, resulted in some fast preheat speeds. The standard setting took only 8 minutes to reach 350°F, while convection mode did so in 9 minutes. Most ovens take longer than 10—especially big ones like this LG. The broiler needed 8 minutes to reach 608°F, which is average.

Warranty

LG covers replacement parts and repair costs for failure due to defects of material or workmanship during the first year from the date of purchase. That part is then covered for the remainder of the warranty period, or 90 days—whichever is longer.
