A control circuit for a clothes dryer operating with a 120 volt power supply compensates for changes in the ambient temperature to compensate for premature advancement of the dryer timer motor during an automatic drying cycle. The control circuit has a thermally biased low outlet thermostat and a thermally biased high outlet thermostat which control the energization of a heater in the dryer. The low outlet thermostat and the high outlet thermostat each open circuit at respective lower and higher predetermined temperatures when the outlet air flow from the dryer drum reaches the lower or higher respective predetermined temperatures to thereby de-energize the heater and advance the timer motor. The control circuit includes a thermally biased ambient thermostat that is normally open and unbiased, and that switches control of the heater energization from the low output thermostat to the high outlet thermostat when thermally biased and when the ambient temperature rises above a predetermined ambient temperature. The ambient thermostat becomes thermally biased when the low output thermostat is open circuited. Both the low and high output thermostats are normally thermally biased during the automatic drying cycle and are un-biased during user time selected drying cycles so that the low and high temperature thermostats cycle on and off at higher temperatures than they would during the automatic drying cycle.

Dryer control circuit

There is disclosed a one-piece ceramic terminal suitable for use for mounting an electrical conductor in insulated relation to a supporting wall of a heating assembly. The ceramic insulator has a central block adapted to pass through a central portion of an aperture in the supporting wall. This aperture has two radially extending slots extending outwardly of the central portion. The ceramic terminal includes a first pair of diametrically opposed radially extending wings which are sized to pass through the radially extending slots in the aperture. The ceramic insulator has a second pair of diametrically opposed radially extending wings which are sized larger than the slots in the aperture so as to engage one surface of the supporting wall. Once the first set of wings pass through the aperture and corresponding slots, the ceramic insulator is rotated such that the second set of wings engage the other surface of the supporting wall so as to mount the insulator relative to the supporting wall. An electrical conductor passes through a central slot in the ceramic insulator and is bent to prevent the insulator from rotating relative to the aperture in the supporting wall and prevent disengagement insulator from the supporting wall.
