Description & Features
The LG WCES6428N wall oven brings professional‑level performance and standout style together in one premium built‑in appliance, ideal for home chefs who want more from their kitchen than a standard double oven can offer. With a generous 6.4 cu. ft. total capacity (4.7 cu. ft. lower oven plus 1.7 cu. ft. upper oven) and a sleek 29.75" width designed to fit a 30" wall opening, it easily handles everything from weeknight dinners to holiday entertaining. What truly sets this model apart is its innovative combination design: the upper cavity functions as a powerful microwave and convection oven, while the lower cavity is a full‑featured True Convection oven, giving you the flexibility to reheat, bake, roast, and brown multiple dishes at once without sacrificing space or performance. The lower oven’s InstaView® WideView window lets you check on roasts, casseroles, and baked goods with a simple knock on the glass, reducing heat loss and helping maintain consistent cooking results. At the same time, the True Convection system with Air Fry and Steam Sous Vide capabilities opens up advanced cooking techniques that many traditional wall ovens simply don’t offer, allowing you to air fry crispy favorites with less oil or achieve restaurant‑quality, tender results using precise steam‑assisted cooking. The exclusive Essence White finish from LG STUDIO gives the WCES6428N a refined, matte look that stands out from typical stainless appliances, complemented by elevated light bronze handles for a sophisticated, furniture‑like presence in your kitchen. Inside, a bright, full‑color 7" TFT LCD touch display guides you through more than 40 auto‑cook recipes and modes, making it easy to select the right settings whether you’re proofing bread, dehydrating snacks, or running a quick EasyClean® or Self Clean cycle to keep the oven interior looking its best. Built‑in ThinQ® smart technology adds even more convenience, enabling remote monitoring, voice control compatibility, and access to smart recipes and notifications from your phone. Altogether, the LG WCES6428N delivers a rare combination of design, capacity, and cutting‑edge cooking features that elevates everyday meals and special occasions alike.

Proof mode – maintains low, consistent temperatures ideal for proofing bread dough.

Warm / Keep Warm function – keeps cooked dishes at serving temperature without overcooking.
