Abstract:
1. A method of controlling motor speed of at least one motor in a dryer by interrupting motor power powering the at least one motor in response to a sensor output related to a parameter other than motor speed which varies with motor speed, comprising the steps of: a) compare the sensor output to a first set point; if the sensor output does not meet the first set point, then repeat this step (a); b) if the sensor output met the first set point in step (a), turn motor power off; c) start a power-off timer; d) compare the sensor output to a second set point and the power-off timer elapsed time to a selected time duration; if the sensor output does not meet the second set point and the power-off timer is less than the time duration, then repeat this step (d); and e) if either the sensor output met the second set point or the power-off timer exceeded the duration in step (d), turn the motor power on, and repeat the method from step (a).
