LG NeoChef brings a stylish sensibility to countertop microwave design, with an elegant, minimalistic look you’ll be proud to showcase in your kitchen. It delivers impressive performance with the power and precision of the LG Smart Inverter, combined with Sensor Cooking—humidity-sensing technology that eliminates guesswork by automatically turning off the microwave when your food is ready. Generous capacity and the splatter-resistant EasyClean interior elevate cooking and cleaning convenience to a new level.

  • Smart Inverter: Try defrosting in an ordinary microwave and you’ll get alternating blasts of full power followed by a periods of no power until the timer goes off. LG Smart Inverter replaces this all-or-nothing approach with precise, variable power that provides more even cooking and better defrosting. Whether you're thawing a pound of meat or reheating last night's dinner, your food is heated more evenly, avoiding cold centers and overcooked edges.
  • Sensor Cook and Reheat: Select from a menu of Sensor Cook options and let the microwave automatically determine when your food is ready using humidity-sensing technology. Get perfectly cooked meals, without the need to worry about cook times or power levels.
  • SmoothTouch Glass Controls: The intuitive SmoothTouch glass controls deliver sleek style and easy operation, with just a touch of your finger. Plus, the smooth surface easily wipes clean for a design that is as practical as it is stylish.
  • EasyClean Interior: Spills? Splatters? Don’t sweat it. LG’s EasyClean interior resists stains and buildup, so cleaning your microwave doesn’t have to be a chore. Simply wipe with a damp cloth—no chemicals, no scrubbing, no problem.¹
  • Hexagonal Turntable Stabilizer Ring: Using your microwave shouldn’t have to be a balancing act. The hexagonal-shaped stabilizer ring on LG NeoChef microwaves provides 6 wheels for the turntable to rest upon instead of just 3. The added support means you can place even tall or heavy items anywhere you like without fear of them tipping over while heating.
  • LED Interior Light: Bright LED lighting makes it easy to check on the progress of your food while offering greater energy efficiency than traditional lighting.
  • 10-Year Limited Warranty on Magnetron: When you buy a microwave, you want something reliable that you can count on. The Magnetron - which provides the power source for the microwave - is confidently backed by a 10-year limited warranty so you can depend on your LG microwave when you need it.

Q: What is a smart inverter?

A: An inverter is an electronic component that can produce a clean power wave as well as modulate it, so cooking is even. For example at 50% and inverter will reduce the power to 50 % versus a regular model the power will still be at 100% but it will be turned on and off by the transformer so the average is 50% (the cooking will not be even). If you do not use power level, the power is always at 100% which is not optimal for most foods.

    Excellent mid-size microwave

    This 1.5 cu ft microwave is the perfect size for my small kitchen — not too big, not too small. The smart inverter technology heats food evenly every time, no cold spots. Build quality feels solid and durable. After weeks of daily use, I have zero complaints. Highly recommend!

    Nice product

    Overall works well. Don’t love the button to open the door - you have to press on 2 different sides

    A Gift for My Parents

    I needed a microwave with specific external dimensions to fit in the shelves of the kitchen. Most 2.0 Cu. Ft. microwaves are too large. I also wanted to make sure the interior was not too small. This model fit the bill (pun intended) and is quiet when operating. The interior is easier to keep clean than the standard white color. The unit was packaged well and my parents are adjusting to having a control panel that does not have numbers to enter. Overall, they are pleased with the gift. They have more internal space than their old microwave and their foods heats in less time.
