6.9 cu. ft. Smart Gas Double Oven Freestanding Range with ProBake Convection®, Air Fry & Air Sous Vide. When ordinary burners can’t keep pace with your on-demand cooking schedule, turn up the power with our flexible UltraHeat™ 20K BTU burner that rapidly goes to high heat for quick boiling, and can also turn down to a true simmer. LG ProBake Convection® brings pro technology home with a combined two-speed fan and ultra-powerful rear heating element. The oven mode automatically selects the lower speed for delicate baking or the higher speed for air frying and roasting. The result is faster preheating, quicker cooking and more even baking on multiple racks at the same time. And with no bottom heating element, cleaning up baked-on spills and splatters is much easier.
