Q: Can this be used without convection? Is it self-cleaning?
A: Yes. The oven bakes very well without convection setting. It is self cleaning.
A: At minimum, the unit requires 1, double pole 30-amp breaker and 10-4 electrical cable. I changed to a double pole 40-amp breaker during my upgrade.
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
A: undefined
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?
A: I imagine LG sells parts
Q: Can I buy the top oven only to replace the exact same oven? The glass is broken on the top unit.
A: Hello there! We understand your inquiry. For your LG WDEP9423D 30" Smart Built-In Electric Convection Double Wall Oven, the top-oven glass is packaged with the full door assembly and isn’t sold as a standalone pane. To ensure you receive the exact replacement, please turn off the breaker supplying power to the oven and allow the cavity to cool completely before handling any parts. This helps prevent accidental shocks and protects internal electronics while you inspect the door assembly. Next, carefully open the lower oven door and locate the model and serial number sticker on the oven frame—this information is essential for matching the correct door assembly part. With these details in hand, please contact us directly so we can provide you the precise parts and assist you further with ordering or scheduling an authorized service visit. https://www.bestbuy.com/site/lg-30-smart-built-in-electric-convection-double-wall-oven-with-air-fry-black-stainless-steel/6534246.p?skuId=6534246 For immediate assistance, send us a private message on Social Media @LGUSSupport, and our team will be more than happy to guide you through the process.

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.

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.

It’s really easy to use and has a lot of great features. We were able to get rid of our standalone air fryer.
