Whenever the fabric selector switch is set to either Regularor Low, contact 1 is closed to contact 2 and line 1 isapplied to the contacts of the control thermostat. Whenthe fabric selector switch is set to Low, contacts 4 to 5of the switch are also closed connecting the windings ofthe small heater in the control thermostat to line 2 throughthe second centrifugal switch in the motor. When thedrive motor is running and the contacts of the controlthermostat are closed current flow through the heater.The heat from the heater causes the thermostat to cycleat a lower drum temperature.The control thermostat senses the temperature of theair in the blower housing and controls the temperature inthe dryer by opening and closing the heater circuit. Whenthe temperature in the drum is below the cycle temperature,the contacts are closed, connecting line 1 to thehigh limit thermostat. The high limit thermostat is asafety device that prevents the dryer from overheating ifthe contacts of the control thermostat fail closed. Thecontacts of the high limit thermostat are normally closedand are set to open at a temperature above the cyclingtemperature of the control thermostat. From the outputterminal of the high limit thermostat, line 1 is connectedto one side of the element. The other side of the heatingelement is connected to line 2 through the contacts ofthe second centrifugal switch in the drive motor. Thisswitch prevents power from being applied to the elementif the motor is not running.The Cycle Signal Circuit:The end of cycle signal circuit is made up of a signalswitch and the cycle signal (buzzer). The signal switchand the cycle signal are connected in series with oneanother and in parallel with terminals B and C of thetimer. Terminal B and one side of the signal switch areconnected to line 1. Terminal C and one side of thecycle signal are connected through the motor centrifugalswitch to neutral. When the dryer is operating, terminalB is connected to terminal C by contacts B and Cof the timer and the cycle signal circuit is shorted out.At the end of the cycle, contacts B and C open and if thesignal switch is closed, current flows through cycle signal(about 5 seconds) until the motor stops and the centrifugalswitch opens.Timed Dry CycleThe time dry cycle operates the same as the auto drycycle except for the operation of the timer motor. Whenthe dial is turned to the timed dry section, contacts TMto X in the timer close connecting the timer motor toneutral through the centrifugal switch in the motor. Thetimer motor then runs continuously until contacts B to Cof the timer opens and the motor stops.Electrical Operation (Electric Dryer with ElectronicMoisture Sensor)Note:Always refer to the wiring diagram orschematic with the product.Sample wiring diagram for models with electronic moisture sensor40
