This Whirlpool(TM) gas dryer ensures well-preserved fabrics and has a 7.4 cu. ft. capacity, which means that there's plenty of room for large items and larger loads. The advanced sensing system uses 3 sensors to constantly monitor humidity and temperature levels by adapting the drying time accordingly, which prevents your fabrics from overdrying. The Wrinkle Shield option protects clean clothes from wrinkles by intermittently tumbling clothes for up to 150 minutes after the cycle ends or until you open the door. Also, the dryer is equipped with intuitive controls that make choosing the right cycle easy and lets you choose between 36 custom settings for optimal fabric care. Finally, 4 baffles tumble the clothes in a randomized pattern, allowing them to move more freely in the tub, which is convenient for smaller loads. It is highly recommended to use a 4" (10.2 cm) diameter rigid aluminum or galvanized steel duct with this product.
