Overview

  • Refined Design
    This is the redesigned LG SIGNATURE. It’s modern flat panels and streamlined pocket handles married with a PrintProof finish that meets your busy family where you live, without leaving a trace. It’s lasting performance combined with capacity and high-end innovations. It’s current, contemporary and stylish, and it’s everything you’ve been dreaming about.
  • Air Fry Setting
    Air Fry delivers crispy flavor fast with no preheating required. Just press Air Fry to prepare favorite snacks like french fries, hot wings and more. High temperatures and the convection fan work together to deliver the flavor and crunch you crave without the oil—or the guilt.
  • Air Sous Vide
    The LG SIGNATURE Over-the-Range microwave elevates your culinary capabilities with built-in Air Sous-Vide technology. This innovative feature uses precise air circulation instead of water to cook food faster, achieving a smooth and even texture while perfectly preserving the food’s natural moisture and nutrients. Enjoy healthier, restaurant-quality results right in your kitchen.
  • Convection Technology
    This microwave with convection technology can serve as a second oven, allowing you to bake or roast your favorite foods in less time.
  • LG ThinQ Smart Technology
    The LG ThinQ app offers control and convenience for smart LG appliances to help you simplify life and enjoy the comforts of home. Manage your microwave’s settings remotely, sync the light and vent with your smart LG range or cooktop, send cooking instructions to the microwave with Scan-to-Cook, and much more.
  • Wide Ventilation Filters
    Cleanup isn’t the most glamorous part of cooking, but wide microwave filters make it easier. They whisk away smoke and steam while cooking and feature a removable design for simple installation and removal.
  • EasyClean Interior
    Spills? Splatters? Don’t sweat it. The EasyClean interior resists stains and buildup¹, so cleaning your microwave doesn’t have to be a chore. Simply wipe with a damp cloth—no chemicals, no scrubbing, no problem.
  • Motion Sense LED Light Bar
    This LG SIGNATURE over-the-range microwave offers lighting that anticipates your needs. Its smart LED Light Bar automatically illuminates the cooktop when you stand in front of the product, providing uniform lighting across a larger surface area as you cook. You can also seamlessly adjust both the brightness and the light temperature from warm white or cool white to perfectly suit your kitchen’s interior concept.
  • PrintProof Finish
    Life doesn’t stop for spills, and your style shouldn’t sacrifice, either. PrintProof fingerprint- and smudge‑resistant finish wipes clean with a soft, dry cloth, helping your kitchen stay distinctive and ready for real life.
  • Scan-to-Cook
    The Scan-to-Cook feature takes the guesswork out of frozen food prep. Simply scan the UPC code² from the ready-made meal into the LG ThinQ app to remotely set oven temperature and cooking time.
  • Auto Cook
    Make life at home even better with easier ways to cook—just select one of the 11 Auto Cook settings on this LG SIGNATURE microwave. Choose from Speed Combi for combined cooking methods, Air Fry, Auto Defrost, Sensor Cook, Sensor Reheat, Soften, Melt, Simmer, Popcorn, Steam Cook or Kids Meal.
  • Sensor Cooking
    Humidity-sensing technology determines when food is cooked and automatically turns off the microwave to help prevent the over- or under-cooking of meals.
  • SmoothTouch Glass Controls
    Intuitive SmoothTouch glass controls provide an upscale look and make it easy to operate your range with just the touch of your finger. Best of all, they have been designed with practicality in mind—the smooth surface easily wipes clean.
  • Turntable
    Continually rotates food to ensure even cooking.
  • 2-Year Limited Warranty on All Parts and Labor
    All LG SIGNATURE appliances are backed by LG’s 2-year limited warranty, so you can confidently enjoy this appliance for years to come.
