ABSTRACT:
A clothes dryer temperature control system or circuit is provided with a thermally biased thermostat adjacent to the air outlet of the drying drum. Further, a thermally biased control thermostat is provided adjacent the air inlet of the dryer drum. The two thermostats are controlled through a multiple contact switch controller which allows the dryer to operate in a high heat, medium heat, low heat, and damp dry heating cycles. Additionally, in a gas dryer embodiment a trimmer thermostat is located in circuit with the thermally biased resistor of the thermally biased air inlet thermostat so as to decrease the response time of this thermostat on its first cycle to prevent damage to clothing during initial operation of a gas dryer.
