LG LRG4115ST Freestanding Gas Range Review
LG's new ProBake system changes cooking for the better.
From the Lab
We put the LG LRG4115ST through our standardized barrage of tests, covering everything from preheat speeds to burner temperatures. Ultimately, the LRG4115ST excelled in most of our tests, although we found the much touted ProBake true convection mode lacking when it came to cookies.
Oven & Broiler Performance

We test oven performance by baking a batch of standardized cookies and a pair of cakes. We then use a photospectrometer to measure variations of doneness. This gives us a precise indication of temperatures variations and circulation within the oven cavity. The standard bake setting resulted in almost perfectly uniform cookies, however the cakes emerged with overdone sections and a wide variation of doneness.
ProBake, on the other hand, did not treat cookies well. We noticed thin items placed near the rear element emerged severely overdone, negating some of the usefulness of this oven's large cavity. Conversely, cakes baked using the convection setting were in better shape than those prepared with the standard bake setting.
One area were the LRG4115ST excelled regardless of cooking mode was preheat speed. The standard setting took only 8 minutes to reach 350°F, while the convection mode needed 10.
The LRG4115ST's gas burners proved more than a match for our tests, and the front two burners should be your go-to's for boiling. The front right burner needed just 4 minutes to boil six cups of water—an amazing result for gas—while the front right took 8 minutes to boil the same amount.
Gas burners struggle to reach the high temperatures electric and induction ranges are capable of, and the LRG4115ST is no exception. The front right burner maxed out at 442°F, and the front left got as high as 420°F. Meanwhile, the right rear reached 352°F, the left rear burner reached 272°F, and the center oval burner peaked at 392°F.
Minimum temperatures were more impressive. The right rear simmer burner dipped down to 110°F, the left rear burner hit 127°F, the right front burner got as low as 151°F, and the left front and center burners managed 149°F and 166°F respectively.
