Questions & Answers

Q:Can I buy parts for WCEP6423D if something breaks? I looked on the LG part page and no parts came up for this model. If I can't order parts, if it breaks, do I just have to buy a whole new one?

    Q:When I use microwave for just '30 seconds'. Microwave goes to 'Oven Cooling' for exactly 3 whole minutes and it's pretty loud. This is very annoying. Is this normal for microwave operation on this LG unit?

    Answer This Question

    A:  Hi, Riya. Thank you for reaching out on the LG Combi Wall Oven (WCEP6423F) model. The "Auto Cool" feature in the manual makes the fan run after cooking to cool down the inside and shows a "Cool" message. It starts right after cooking or 10 to 15 seconds later, not for 3 minutes after 30 seconds of use. A 3-minute loud cooling cycle is not normal for an LG over-the-range microwave oven. For more info, visit https://www.lg.com/us/support/help-library/lg-microwave-troubleshooting-loud-noise-while-cooking--20153194328721.

      Q:Does the WCEP6423D have delay start? And what happens if the microwave breaks down? Would I have to replace the whole unit?
      by|Apr 23, 2024
      1 Answer
      Answer This Question

      A:  Hey there! This oven has a delay start feature! Press "Start Time" and set your desired time for the delayed cook. The oven starts and stops at the times you select. It works with Bake, Conv. Bake, and Conv. Roast modes. Be careful when using Delayed Timed Cook. Use the automatic timer for cured/frozen meats, fruits, and vegetables. Let us know if you have any questions. ^Anthony

        Q:This oven has so many top of the line features, but no gliding rack!?!? Will LG ever make a glider rack for this model? Is there any aftermarket glider rack that would work?
        by|Apr 14, 2024
        1 Answer
        Answer This Question

        A:  Thank you for your interest in the LG Wall Oven. Yes, there are specific gliding oven racks available for LG ranges and ovens, and it may be possible to find a compatible gliding rack for the LG WCEP6423D model through LG or authorized retailers. kindly coordinate with the dealer where you'll buy your LG appliance. You can visit this website for more options and more information: https://www.lg.com/us/search?q=gliding%20oven%20racks&searchWithin=false&oldTerm=. ^Cris

          ThinQ feature
          Works great, yet a bit loud on cool down mode. Really like the ThinQ features with all the LG products. LG 1.7/4.7 CU. FT. SMART COMBINATION WALL OVEN WITH CONVECTION AND AIR FRY

          Excellent Oven and Microwave Combination
          The top is a microwave that heats incredibly evenly. I'm mid kitchen renovation and once I got this installed, I've used the microwave several times and it cooks much better than my stand-alone microwave. The top doubles as a second convection oven, will broil, and warm/proof bread. The bottom is your standard oven with convection and also will air fry. The air frier works incredibly well. I was able to do a big 5+lb bag of tots and they came out nice and crispy.

            Great appliance
            We purchased the LG oven to match our refrigerator. We like the no fingerprints feature. The oven and microwave work great as expected. We were disappointed with the control buttons because they don’t light up. Hard to see in low light. Probably will get use to this with more use. We gave a high rating for overall performance, features, and looks.

            Thin and awesome
            [This review was collected as part of a promotion.] This oven i installed in my kitchen and I love it. Love that its the thinQ which is perfect for having a fridge next to it. My previous oven was a 27" and I still had issues with the fridge door hitting oven handle and this one solved that problem. I like that the microwave can be used as a conventional oven and my wife really likes the airfryer. It works really fast and we can have our food done in minutes compared to the table top airfryer we've been using because of our large family we can have all the food in at once. This have so many cool features that we still figuring it out.
              UPSCALE, MODERN, SMART
              This is not only the first wall mounted unit we've owned, but also the first smart oven too. This model has smart features that are perfect for the family that's savvy with having features that can be operated through an App on your cell phone.The quality of the build on this combo oven is impressive to say the least. From it's finger print free stainless out side to it's deep blue ceramic interior it's a sight to behold. The glass touch control panel is also very nice and will be easy to keep clean without leaving scratches.Very modern, clean and upscale in it's overall appearance.It's a beast weighing in at just over 200 lbs so you'll need several people to get it in your home and set it in it's final installation space.I can't comment on how well it cooks yet since we got this just a few weeks before Christmas and haven't found a contractor yet who can install it, although based on past reviews of older LG Oven models one can be certain that reliability will be good at worst. I do love that we'll be able to get the cooking results of an oven with microwave speed as stated in the description. The difficulty with any newer model appliance, which this is, is that there's no long term reviews of them under normal use, although the sales person at one store shared that he himself has had a whole kitchen full of LG appliances for almost two years and has had no issues.And in his opinion he also shared that he felt that the LG appliances were a very good value over other brands that were more expensive.It's always a good idea if your planning on purchasing one of these combo's is to have your cabinetry and electrical connections( 240 volt) ready before your appliance arrives.If HD will allow it I'll revisit this site in a few months from now and post another review on this oven combo and share my experience having used it under real life over time.The one major concern I have with micro wave oven combo's is the fact that microwaves in my experience have not held up well over a longer length of time and once they go they can't be repaired whereas regular ovens do and can be repaired and if I'm not mistaken once the microwave goes out I'm not sure that it can be replaced independent of the oven.This is a question I'm going to ask LG and perhaps one you might also consider before purchase. Otherwise I'm, so far,extremely happy with the way this unit looks and am excited to eventually be able to use the impressive features this combo has.

              Good - Not Great
              This air Fryer, Oven, Microwave combo is good, but I would say not great. I'm used to a 1500 watt microwave, so not sure how the 950 watt version in this Combo will match up. Although my biggest concern is the pull down door on the top oven. I could see how this might get in the way - especially for shorter people. I think I would prefer the more conventional swing right or left microwave door. Of course all of that is subject to the mounting height of the unit. Otherwise, the unit has a beautiful dark stainless fingerprint proof finish that is very nice looking. The upper over is all stainless inside for a very clean look. The bottom oven has an almost shocking blue color - nice finish, but doesn't really go with the rest of the unit. Lots of nice features and a great exterior look and finish.

              Easy install looks great
              The Lg oven i installed in my kitchen is exactly what i needed. I previously had a 27inch micro-oven and it was too small for us because we cook alot. This oven fit perfectly in my 33 inch oven cabinet and i had to do some cutout to fit the oven in. The instructions were simple and i was able to have my wife help me lift it in and it looks awesome. I like that it comes with several pans and a mesh basket for the oven. I like that this oven has airfry because we do use our small air fryer and hopefully this with much more space works the same. I love the black stainless look and the blue oven interior. I love that the microwave could be used as an oven too and has many neat options. The installation was much quicker than i thought it would be. Took me about 1hr to remove old one and install this one. This requires 40amp breaker. Love it thanks

              Good upgrade.
              Glad i got the fan convection/air fryer combo. When upgrading out kitchen, we wanted to go back to dedicated oven/microwave vs a microwave on the counter+ range. This was a great option. Love the blue inside the oven. I do feel like it does save more time and cooks more evenly than our last oven. It's new so it's easy to clean and i expect it to remain easy to clean. This requires 40 amps (like a car charger) so be sure your wire and breaker is set up for it. Can't and shouldn't share it with anything else or it'll trip the breaker often. I hope the electronics last. Our last oven was manual and gas and also 60 years old with no issues.

                Good but a serious problem
                [This review was collected as part of a promotion.] Good but a serious problem. Functions are fine. The problem is that only the center numbers on the control panel light up. The vast majority of choice blend in with the background. There is no option to light them apparently. What a flaw! Even with strong lights in the room, the options are hard to read!
                Response from LGJun 6, 2024
