Overview

  • 7.4 cu. ft. Ultra Large Capacity
    Free up your day—fit more clothes in every load with 7.4 cu. ft. of space. Running fewer loads saves energy and money on your utility bill.
  • FlowSense Duct Clogging & Lint Filter Indicators
    FlowSense Duct Clogging and Lint Filter Indicators let you know when your ducts and filter need cleaning to avoid lint buildup, improve the dryer’s performance for greater efficiency and lower utility bills, and help give you safer, worry-free operation with fewer service calls.
  • LoDecibel Quiet Operation
    Run the dryer whenever you want, without interrupting naptime or your favorite show. This dryer is designed for quiet operation, from the motor to the cabinet to individual components. Pleasant end-of-cycle chime lets you know when clothes are dry.
  • 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 and monitor your dryer remotely, track and download cycles, connect with Google or Alexa voice assistants, and access smart diagnosis, customer support, and much more.
  • Built-In Intelligence: AI Sensor Dry / Smart Pairing
    Forget about endless sorting or toggling through cycles—built-in sensors use AI technology to detect fabric texture and load size, then automatically select the right drying motions, temperatures and more for advanced fabric care.
  • AI Sensor Dry detects moisture levels and automatically adjusts drying time for loads of all sizes—no more damp clothes, no more overdrying. With Smart Pairing, the washer can even tell the dryer to select a compatible drying cycle¹, making it the ultimate laundry hack.
  • LG ThinQ UP
    ThinQ UP enabled smart appliances may receive software updates for new downloadable features and enhancements to be sent wirelessly to the appliance. Choose which features you want and customize your appliance based on your lifestyle and personal preferences.
  • LG ThinQ Care
    Available within the LG ThinQ app, ThinQ Care sends proactive usage, maintenance, and diagnostic alerts to your smartphone, notifying you of potential issues and helping you keep your smart LG appliances running smoothly.
  • ENERGY STAR Certified
    High efficiency sensor drying and low-heat settings save energy and money by using about 20% less energy² than conventional models without sacrificing features or performance.
  • Aluminized Alloy Steel Drum
    An advanced aluminized alloy coating is added to the steel dryer drum to enhance durability and maintain its luster and attractive finish. Helps keep nicks and chips at bay so your dryer looks like new even after years of use.
  • Reversible Door
    When space is tight or your laundry room doesn’t fit the “typical” setup, this dryer’s door can easily be reversed to fit your needs. Go from a right swing to a left swing in minutes—just unscrew the hinges and reattach using the pre-drilled holes on the opposite side.
  • Wrinkle Care Option
    When you hate wrinkles but can’t be there to remove clothes as soon as they’re dry, just select the Wrinkle Care option before hitting start. The dryer will periodically tumble the load for up to 3 hours after the cycle is done or until the door is opened to help keep wrinkles at bay.
  • Closet Depth
    LG closet-depth washers and dryers are worth showing off, but when space dictates otherwise it’s good to know they’ll easily fit in a closet with plenty of room to close the closet door. Install the pair side-by-side, or get a stacking kit and install the dryer over the washer to save even more space.
  • Dryer cords are not shipped with the dryer.
    It is the responsibility of the consumer to purchase the appropriate cord for their home.
