Questions & Answers

Can it be mounted over the range?
ByOct 7, 2026
1 Answer | 
Answer This Question

The LG NeoChef™ 1.5 cu. Ft. 1100-Watt Countertop Microwave in Stainless Steel with Smart Inverter, Model # MSER1590S, is strictly a 'Countertop' microwave oven, as indicated in its title. It cannot be mounted over a range oven. It does not have the necessary built-in exhaust fan or heat shielding required to handle the rising heat, steam, and grease from a cooktop. Installing a countertop model over a range poses a significant safety hazard and will void your warranty...^Ivan.

          Does it fit over the range
          BySep 17, 2026
          1 Answer | 
          Answer This Question

          As indicated in its title, the LG NeoChef 2.0 cu. Ft. 1200-Watt Countertop Microwave in Stainless Steel with Smart Inverter, Model # MSER2090S, is a COUNTERTOP microwave oven. It is specifically built as a countertop microwave, and it cannot be installed over a range oven. LG Countertop Microwave ovens are not engineered to handle the intense heat, steam, and rising grease coming from a cooktop or range. They do not feature the underside exhaust fan, recirculation system, or grease filters necessary to clear cooking vapors from your stove, nor do they have the structural top-and-rear mounting mechanisms needed to anchor securely to a wall bracket or an upper cabinet overhang...^Ivan.

                Does the +3 second button automatically start the microwave
                BySep 13, 2026
                1 Answer | 
                Answer This Question

                Hi. We understand your inquiry regarding the LG MSER2090S microwave. The microwave features a "+30 SECONDS" button (rather than a +3 second button) that automatically starts the microwave for 30 seconds at 100% power when pressed, and each additional press adds 30 seconds to the running time. You can access complete operating instructions and product details on our official support page at https://www.lg.com/us/support/product/lg-MSER2090S.BSTELGA?tab=1 and downloading the operation manual. Please send us an email at lgdigitalcare@lg.sprinklrsupport.com if you need further assistance on your inquiry or if you have further questions.

                  Broke after just a year
                  The magnetron blew up and let out the magic smoke after just a year or so. By blowing up, I mean the magnetron started arcing to the metal body. Good thing I was right there to stop it before a fire started.

                    Our 20+ year old over the range 1.5 cu. ft. microwave broke down and had to be replaced. We decided to remove the broken one, add a shelf above the range and replace the old unit with this smaller portable unit. For the last week that we have had it we are very pleased with the new LG, it suits our cooking size requirements much better than the huge old machine. The controls are simple and intuitive. Even though the cooking power is reduced we only need to adjust the cooking times slightly to compensate. A damp paper towel is all that's required to wipe away any fingerprints or smudges and leave it looking perfect.

                    Hello there, and thank you for sharing your experience with the LG Standard-Depth InstaView MyColor 28.6-cu ft 36-in Wide French Door Refrigerator (LF29S8365S). We’re glad to hear the compact design and intuitive controls are fitting well into your updated kitchen setup. It’s great that the cooking performance meets your needs with just slight time adjustments, and we appreciate you highlighting how easy the exterior is to maintain. If you ever want to fine‑tune heating results, we recommend checking that the unit is placed on a stable, flat surface with at least 3 inches of clearance on all sides to support proper ventilation. For quick upkeep, using a mild detergent with warm water on the interior can help maintain consistent performance over time.

                    Just OK
                    The unit functions ok. The end of cooking tone is very subdued. It should be louder or there should be a way to adjust the volume. With the slightest ambient noise, it is imperceptible. The worst "feature" of the unit is the fact that they usually last about one month past the warranty! This has been the case four times now! The main reason that we keep buying the same one is because it is been built-in into our kitchen cabinets. Otherwise, we would have 'moved on' from this particular unit by now.

                    Hello there, thank you for taking a moment to share your experience with your LG NeoChef 2.0 cu. ft. Countertop Microwave MSER2090S.

                    We appreciate your continued use of this model, and we understand how important clear alerts and dependable performance are in a built‑in setup. The end‑of‑cycle tone on this unit has a softer profile, and you can confirm the Sound setting is switched on in the control panel. For added consistency, we recommend a quick reset by unplugging the microwave for 30 seconds and ensuring the vents have open airflow.

                      I like the ease of setting the time to cook. The heat is very even due to larger roller ring. I do not like the control pad, the numbers are not bright enough to see.

                        Rusted.
                        2 years ago or more I bought this and was annoyed right away by the request by Home Depot to write a review of a product I had literally just taken out of the box. Accurate reviews come after a period of service. It rusts on the inside. Shortly after I purchased it, but after I was asked for my review, a small bit of rust appeared and it has spread rapidly around the whole bottom. The digital clock broke. One of the LED segments stopped working a year into service which sometimes causes it to display an incorrect time. Annoyed that my old calculator from the 80's still works, but this one failed so soon. Awkward control to add time at only 30 second intervals, meaning a 10 minute cook requires 20 pushes of a button. A numbered pad or a dial would be a better interface. Uneven heating of food, even after repositioning and reheating right away. Overall, I give it a poor performance rating. Would not recommend.

                        Hi, Ash. Thank you for reaching out about your LG Microwave (MSER0990S) model. We understand the importance of having a microwave that delivers long‑term reliability, clear visibility, and easy‑to‑use controls. Since you’re seeing rust inside the cavity, one helpful step you can try is wiping the interior with a baking‑soda‑and‑water solution to neutralize any moisture or residue that may accelerate corrosion. For the display issue, performing a power reset by unplugging the unit for 60 seconds can sometimes help stabilize the clock segments if the control panel is experiencing minor communication errors. For more guidance, visit https://www.lg.com/us/support/help-library/lg-microwave-cleaning--20154856102019. We’d be glad to take a closer look at your experience and assist you further.

                          Works great until it dies at 15 months
                          This microwave worked well after purchase in September 2024. In early January 2026, the unit started to not heat well and by the end of the month stopped heating entirely with popping sounds and sparks when trying to use the unit. Waited for 17 minutes for LG chat to provide assistance with no response. Do not recommend.

                          Hi, LeeLee. Thank you for sharing what’s been happening with your LG Microwave (MSER2090S) model. We understand the importance of having a reliable unit that heats consistently, especially after it performed well for over a year. For a microwave that stops heating and shows signs like popping or sparking, one helpful step is to unplug the unit and inspect the interior for any damaged waveguide cover or debris, as a compromised waveguide can cause arcing and prevent proper heating. For more guidance, visit https://www.lg.com/us/support/help-library/lg-microwave-why-is-my-microwave-not-heating-properly--20153229630502. We’d be glad to take a closer look from our end.
