Q: what is the cabinet openg size required to install this oven
A: Hight - 52 13/16 inches Width - 28 1/2 inches Depth - 24 inches
Q: How much space does the convection feature take up inside the oven
A: Hello there, Patti. Thank you for your inquiry regarding the WDEP9423D. We understand your inquiry about the space utilized by the convection feature. Based on the specifications, this unit features Fan Convection which is integrated into the back of the oven cavity to maximize the 9.4 cu.ft. total capacity and does not significantly encroach on the cooking area. Your feedback is important, and we'd like to assist you further. https://www.bestbuy.com/product/lg-30-smart-built-in-electric-convection-double-wall-oven-with-air-fry-stainless-steel/J7G5658JHH If you have any further questions about its features, please contact us on [email protected], and our team will be more than happy to assist you. —Renzo
Q: My current wiring is 8/3 do I need to upgrade to 8/4 to install this oven?
A: Regrettably, we are not qualified electricians, and we highly recommend you consult a licensed electrician for specific installation requirements and codes in your area. The recommended wire gauge for the LG 30" Smart Built-In Electric Convection Double Wall Oven with Air Fry - Stainless Steel, Model # WDEP9423F, is 10 AWG, and 8/3 is allowed for a wall oven that calls for 10 AWG wiring. The 8/3 wire configuration consists of two hot wires, a neutral wire, and a ground wire, which is suitable for 240-volt circuits. The recommended protection circuit for this wall oven is 40 Amps, and the wall oven must be electrically grounded in accordance with local codes or, in their absence, with the National Electrical Code ANSI/NFPA No.70- latest edition, so you will need to check your local building codes or consult your local building inspector or a qualified electrician about whether an 8/3 wiring or 8/4 is allowed in your area. New branch-circuit installations (1996 NEC), mobile homes, recreational vehicles, or installations where local codes prohibit grounding through the neutral conductor require a 4-wire branch-circuit connection. If your local codes permit a connection of the frame grounding conductor to the neutral (white) wire, you can follow the instructions for a 3-wire circuit connection...^Ivan.
Q: does it have a third heating element around the convection fan?
A: Hello there. Thank you for sharing your inquiry with us. We understand your inquiry regarding the heating configuration of the WDEP9423D Double Wall Oven. Based on the specifications for this model, it features Fan Convection rather than "True Convection." This means the unit uses a fan to circulate the heat generated by the main Bake (2500 W) and Broil elements to ensure even cooking, but it does not list a dedicated third heating element located around the fan itself. https://www.bestbuy.com/product/lg-30-smart-built-in-electric-convection-double-wall-oven-with-air-fry-stainless-steel/J7G5658JHH If you have any further questions about its features or cooking modes, please send us a private message on Social Media @LGUSSupport, and our team will be more than happy to assist you. —Renzo
Q: How can the cut out height be bigger than the product height?

I got the LG 30" Smart Built-In Electric Convection Double Wall Oven with Air Fry, and I love it. It’s super spacious — way bigger inside than I expected — and it cooks really evenly. The air-fry and convection settings work great, and the controls are easy to use. But honestly, my favorite part is how it looks. It’s absolutely gorgeous in person and gives the kitchen a really clean, modern vibe. Overall: big, beautiful, and works perfectly. Totally recommend it.

We love the air fryer function! Preheats quickly and temp is accurate.

We had been wanting a double oven for awhile. Previously we had an oven and a built in microwave above. Fit great in the space allocated. Having the wifi capabilities makes it even better. Has already come in handy hosting, being able to cook two different items at different temperatures to serve hot.
