7.4 Cu. Ft. Ultra Large Capacity Smart Front Load Gas Dryer - DLG3421W

Smooth, Quiet Performance

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.

Built-in Intelligence Takes Out The Guesswork

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.

Who Says Dryers Can't Be Energy Efficient?

High efficiency sensor drying and low-heat settings save energy and money by using about 20% less energy than conventional models without sacrificing features or performance.

Win the War on Wrinkles

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.

Spend Less Time On Laundry With More Room For Clothes

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.

Greater Installation Flexibility

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.

More Style, Less Space.

LG closet-depth washers and dryers have a shallower depth to fit in more places & add sleek style to any room.

Keep Your Dryer Clean, Efficient And Safe

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.
