摘要： A method for controlling a laundry treating apparatus includes an air supplying step of supplying heated air to the drum through the heat exchange part and a first motion executing step executed while the air supplying step is in progress. The first motion executing step alternately executes a first acceleration mode of rotating the drum at an rpm inducing a centrifugal force equal to or greater than 1G along one of a clockwise direction and a counterclockwise direction and a first deceleration mode of rotating the drum at an rpm inducing a centrifugal force smaller than 1G in a direction equal to a rotational direction set for the first acceleration mode.
