Abstract: A control system for a clothes dryer comprises an exhaust temperature detector, a comparator for outputting a signal when either the exhaust temperature or the rate of change in exhaust temperature attains a value higher than a predetermined value, a first timer for counting the time elapsed from the start of operation up until the generation of the signal from the comparator, a calculator for determining the time, during which an electric power is subsequently supplied to a heater, in correspondence to the time counted by the first timer, a temperature adjustment capable of generating, when the exhaust temperature is higher than the predetermined value, an output signal necessary to cause a first control to interrupt the supply of the electric power to the heater, a second timer for counting the length of time determined by the calculator, and a second control operable in response to the output from the second timer for deenergizing both the heater and the motor.
