  • Publication number: 20080065244
    Abstract: A household appliance functions according to multiple operating cycles, wherein each operating cycle comprises at least one step characterized by a parameter having a factory-set default value. A user can access a controller of the household appliance through a user interface to simultaneously set new default values for a parameter common to at least two of the multiple operating cycles.

  • Publication number: 20070186438
    Abstract: A method of drying clothes in a clothes dryer comprising a clothes chamber for receiving clothes, an air supply system for directing air through the clothes chamber, and a heater for heating the air supplied by the air supply system. The method comprises cycling the heater between an ON state by energizing the heater until a heater trip condition is met and an OFF state by deenergizing the heater until a heater reset condition is met, determining a heater off time by determining the time between the heater trip condition and the heater reset condition, and determining a drying time based on the heater off time.

  • Publication number: 20060201019
    Abstract: A clothes dryer has a system for regulating the inlet air temperature. The system includes a first sensor located in an inlet of the dryer and including a thermistor and a thermostat, a heat source located in a heater box adjacent the first sensor, and a second sensor located in an exhaust of the dryer. The thermistor measures the inlet air temperature of the dryer and cooperates with the controller to prevent the thermostat from reaching its trip temperature and turning off the heat source. Thus, damage due to excessive air temperatures in the dryer is prevented.
