As for the second motor, a variable speed motor is used and amount of heating of a heater of the clothes dryer is variable. In the method for controlling an operation of a clothes dryer, the cooling fan is operated when a predetermined period of time passes after the cooling fan being stopped during an initial operation, or the cooling fan is operated at a regular speed when a temperature of air circulating reaches a predetermined degree after the cooling fan being operated at a low speed during the initial operation of the clothes dryer.
