FEATURES AND LOOK

Ultra Big Capacity Drum

The LG Dryer has a large capacity.

Reduced drying time

Drying time is shortened by efficient air flow mechanism and

optimized heater.

Innovative Noise Reduction

Noise is reduced by optimized design of air flow system and vibration

reduction technology.

Ease of Use

Large LED display and electronic control.

Your dryer provides sensor drying and manual drying programs.

Sensor Dry Dryer electronically senses laundry moisture level and it automatically determines operation time

based on the dryness of the load and the selected program. At times,you can see sudden increase or

decrease of operation time. It happens because a sensor will detect laundry humidity with a certain period.

Sudden change of operation time is not a malfunction.

Manual Dry Manual Dry allows you to set operation time manually to complete drying. Or use Manual Dry if

clothes are still damp after sensor dry cycle is finished. Manual Dry is more effective for heavyweight and bulky

items such as king-size bed sheets and thick work clothes.
