  • Patent number: 4642907
    Abstract: A control circuit for a clothes dryer wherein a resistor connected in series with a timer to reduce supply voltage to ensure proper operation of the timer, is mounted adjacent an operating thermostat to provide thermal bias. Timer run-out is provided by the inclusion of a back contact on a drive motor centrifugal switch along with a resistor, so that the timer continues to run through its cycle in the event of the interruption of the dryer motor. Timer run-out is also provided in another embodiment which includes a centrifugal switch in series with the operating thermostat in a timer shunting circuit so that the shunt is removed upon interruption of the dryer cycle to supply power to the timer.
