A dryer includes a drum receiving an object to be dried, a first sensor configured to sense a dry state of the object to be dried contained in the drum, a heater configured to heat air supplied into the drum, a blower including a fan forming a flow of air passing through the inside of the drum, a second sensor configured to sense a temperature of air discharged from the drum, and a processor configured to control, when a user input selecting a specific course is received, the drum, the heater, and the blower to perform a dry cycle, to control a rotation direction of the drum on the basis of a dry state of the dry object sensed by the first sensor when the dry cycle is started, and to control termination of the dry cycle on the basis of the temperature of air sensed by the second sensor.
