4.6(5 reviews)

The LG WDEP9423F is a 30-inch smart wall oven that combines true convection, built-in air fry, and steam cooking in one black-stainless package. The 4.7 cubic foot cavity handles a 30-pound turkey, and the air-fry mode circulates superheated air for crispy wings and fries without preheating a separate appliance. The steam function adds moisture for roasts, reheats leftovers without drying them out, and helps with bread baking. ThinQ Wi-Fi integration enables remote preheat, voice control through Alexa and Google, and proactive maintenance alerts. EasyClean is a quick 10-minute steam-assisted wipe-down, and a traditional self-clean is also available. Recommended for homeowners who want air fry plus steam in a distinctive black stainless finish.

Three functions in one oven

Installed the LG WDEP9423F in our home in suburban San Jose, CA, four months ago. The combination of true convection, built-in air fry, and steam cooking in a single wall oven is the standout feature. The air fry mode crisps wings and frozen fries without preheating a separate appliance. The steam function adds moisture for bread baking and keeps roasted meats juicy. The 4.7 cubic foot cavity is generous for a 30 pound turkey. ThinQ Wi-Fi connectivity enables remote preheat through the LG app and works with Alexa and Google Assistant for voice control. EasyClean offers a quick 10-minute steam-assisted wipe-down for light messes. Black stainless finish hides fingerprints. Excellent oven. Two more notes for anyone considering this LG oven: EasyClean is a quick 10-minute steam-assisted wipe-down that handles light messes without specialty cleaners, and the traditional self-clean cycle is available for heavier residue. ThinQ Wi-Fi connectivity works reliably for remote preheat and voice control through Alexa and Google Assistant. The black stainless finish is fingerprint-resistant and stays clean with weekly wiping. The 4.7 cubic foot cavity handles a 30 pound turkey plus sheet pans of sides. LG customer service has been responsive when I had a small installation question. Highly recommend for design-conscious cooks.

Black stainless looks great

Bought this LG wall oven for our home in suburban Atlanta, GA, primarily for the black stainless finish and the air fry plus steam combination. The black stainless hides fingerprints far better than regular stainless, and the air fry mode crisps wings and fries without a separate appliance. Steam function adds moisture for bread and roasts. The 4.7 cubic foot cavity is plenty for a holiday turkey. ThinQ Wi-Fi lets me preheat from my phone and voice control through Alexa and Google Assistant is useful. EasyClean is a quick 10-minute steam-assisted wipe-down that handles light messes. Took off one star because the steam reservoir is small, but overall a versatile, beautiful oven for design-conscious cooks. Two more notes for anyone on the fence: the hidden bake element keeps the floor of the cavity smooth so spills do not get trapped under a coil, and the self-clean with steam option is far faster than the deep cycle on our old oven. We run the steam cycle about every three weeks and wipe the interior with a microfiber after cool-down. The control panel is intuitive and the small status display is bright enough to read across the kitchen. Overall this oven has earned its space in our home and I would buy it again without hesitation.

Premium in every way

Replaced an older wall oven with this LG WDEP9423F at our home in suburban Minneapolis, MN. The combination of true convection, built-in air fry, and steam cooking makes this oven incredibly versatile for the price. The air fry mode crisps wings and frozen fries, the steam function keeps roasted meats moist and helps with bread, and the 4.7 cubic foot cavity handles a 30 pound turkey comfortably. ThinQ Wi-Fi lets me preheat remotely and voice control works through Alexa and Google Assistant. EasyClean offers a quick 10-minute steam-assisted wipe-down. Black stainless finish is fingerprint-resistant. LG customer service has been responsive when we had a small installation question. Highly recommend.

Air fry plus steam both work

The 4.7 cubic foot cavity handles a 30 pound turkey or multiple sheet pans comfortably. ThinQ Wi-Fi lets me preheat from the office and the oven works with Alexa and Google Assistant for voice control. EasyClean is a quick 10-minute steam-assisted wipe-down that handles light messes. Black stainless finish resists fingerprints. Premium feel, premium performance. Highly recommend for design-conscious cooks.

Air fry plus steam, great value

We chose the LG WDEP9423F for our remodeled kitchen in suburban Philadelphia, PA, because the combination of air fry, steam, and true convection is hard to find at this price. The air fry mode crisps wings and fries without a separate appliance, and the steam function keeps roasted chicken juicy and helps with bread baking. The 4.7 cubic foot cavity is plenty for a holiday turkey. ThinQ Wi-Fi lets me preheat remotely through the LG app and voice control works with Alexa and Google Assistant. EasyClean is a quick steam-assisted wipe-down. Black stainless finish hides fingerprints with weekly wiping. Took off one star because the control panel takes a couple of days to learn, but overall an excellent versatile oven. Two more notes for anyone considering this LG oven: EasyClean is a quick 10-minute steam-assisted wipe-down that handles light messes without specialty cleaners, and the traditional self-clean cycle is available for heavier residue.
