- 1 - Abstract: A control system for a clothes dryer comprises an exhaust temperature detector and 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 measures the time elapsed from the start of operation until generation of a signal from the comparator. A calculator determines the time during which electric power is supplied to a heater corresponding to the time measured by the first timer. When the exhaust temperature is higher than the predetermined value, a temperature adjustor generates an output signal that causes a first control to interrupt the supply of power to the heater. A second timer measures the length of time determined by the calculator, and a second control operates in response to the output from the second timer for deenergizing both the heater and the motor. The result is an arrangement that avoids under or over drying better than prior machines.
