A clothing dryer (10) and a control method thereof that adjusts a heater capacity based on a humidity change amount (a drying rate) in a second half of a drying period to reduce power consumption without increase of drying time. The clothing dryer (10) includes a drum (30) to receive clothing, first and second hot air heaters (36,38), having different capacities, to supply hot air into the drum, a humidity sensor (6) to sense internal humidity of the drum, and a controller (110) to calculate a humidity change amount in the drum (30), to compare the calculated humidity change amount with a predetermined change amount, and to control only one having the relatively small capacity selected from the first and second hot air heaters (36,38) to be operated when the humidity change amount is greater than the predetermined change amount. |
