Abstract: A controlling method for a dryer is provided. The controlling method includes the steps of rotating a drum in a first direction and a second direction which is an opposite direction to the first direction by a motor, measuring the load of the motor and identifying the weight of drying materials based on the lower motor load among the load of the motor measured during rotation in the first direction and the load of the motor measured during rotation in the second direction.
