  • QuestionIf and when microwave needs to be repaired or removed, will the oven work without microwave being there?

    Asked by Jake.

    • Answer Hello there. The LG 30" Built-In Electric Convection Combination Wall Oven with Microwave and Steam Sous Vide is a combination appliance that includes a microwave, oven, and steam sous vide functionality. If the microwave needs to be repaired or removed, the oven will still work independently. The microwave and oven are separate units within the combination wall oven, so the oven can still be used for baking, roasting, and other cooking functions without the microwave being present.. Thank you. —Kai

  • QuestionWill i need to have a water line installed for the steam function

    Asked by Kev.

    • Answer Hello, Kev. The LG wall oven model WCEP6427F does not require a water line installation for its steam function. This oven uses a built-in water reservoir that you manually fill when needed for steam cooking. There is no plumbing required, making it convenient and easy to use without additional installation complexity. If you have any more questions or need further assistance, feel free to ask. ^Sam

  • QuestionWhat material is the air fryer basket made out of? I'm very cautious of cooking with PFAS (forever chemicals/traditional non stick coatings) and before buying this product I want to make sure there aren't any toxic chemicals that will leech in to my food

    Asked by mmey.

    • Answer Thank you for your interest in the LG 1.7/4.7 cu. ft. Smart Combination Wall Oven with InstaView®, True Convection, Air Fry, and Steam Sous Vide (WCEP6427F) model. The air fryer basket of the LG WCEP6427F is made of metal with a Teflon coating. Teflon is a brand name for a type of non-stick coating, and it is important to note that Teflon coatings may contain PFAS (per- and polyfluoroalkyl substances), which are sometimes referred to as "forever chemicals."

  • QuestionWhen using the upper oven for air fry, bake, conv bake, or any other non-microwave function, do I need to remove the plastic shaft that spins the microwave plate?

  • QuestionThe customer reviews of prior model (LWC3063ST) had complaints that the microwave required the operator to hit cancel button to stop vs simply opening the door. Also could not hit number to quick start for X minutes. Does the WCEP6427F fix these issues?

    Asked by Jerry.

    • Answer Hi, Jerry! The cancel button will have to be pressed in order to stop the operation of the WCEP6427F; we'd strongly recommend against running the unit with the door open! The control panel doesn't have a quick start feature that can be set to X minutes, but there is a +30 mode that functions the same way. ^Ian

    • Answer Please pardon us, but we are unclear about your inquiry for the LG 30" Smart Built-In Electric Convection Combination Wall Oven with Microwave and Steam Sous Vide - Stainless Steel, Model # WCEP6427F, and will need clarification.

    Asked by Anonymous.

    • Answer What specific light are you inquiring about on the panel for the LG 30" Smart Built-In Electric Convection Combination Wall Oven with Microwave and Steam Sous Vide - Stainless Steel, Model # WCEP6427F?

  • QuestionIf using the microwave function, do you need to wait for a cool down period if you need to re-start the cooking if food needs to be cooked more? Reviews suggest that after even a few seconds of cooking, if stopped, must wait a minute or so to restart

    Asked by Anonymous.

    • Answer Hello there. We understand your inquiry about the cool-down period on your LG 30" Smart Built-In Electric Convection Combination Wall Oven. Your feedback is important to us. The LG WCEP6427F model, like many combination ovens, features a cooling fan that may run after the microwave cycle has finished. This is a normal operation designed to protect the internal components and is not a defect. The fan helps to dissipate heat from the magnetron and other electronics. While it may seem like a short waiting period is required, you should be able to restart the microwave after the fan has finished its cycle. https://www.bestbuy.com/product/lg-30-smart-built-in-electric-convection-combination-wall-oven-with-microwave-and-steam-sous-vide-printproof-stainless-steel/J7G56587FJ We can further assist you with this and provide more specific guidance.

  • QuestionCan I use this oven in Jamaica? I plan to ship it. The only difference is we use 60hrz and they work in 50hrz. Does this matter with the oven microwave combo?

    Asked by Pamy.

    • Answer Regrettably, we do not know what the rules and regulations are in Jamaica. In the US., the LG 30" Smart Built-In Electric Convection Combination Wall Oven with Microwave and Steam Sous Vide - Printproof™ Stainless Steel, Model # WCEP6427F, must be electrically grounded in accordance with local codes or, in their absence, with the National Electrical Code ANSI/NFPA No.70- latest edition. It requires a single-phase, 3 wire, A.C 120/208 V or 120/240 V 60 Hz electrical system, and has a power consumption of 7.8 kW at 240 V so a 50 A protection circuit, and a 10 AWG wire gauge is recommended. The deviations between 50 and 60 Hertz are small and may not matter, but you would best advised to consult a qualified electrician...^Ivan.
