1. A method for controlling an operation of a clothes dryer having a treating chamber, an environmental drying sensor for sensing an environmental condition in the treating chamber and used to control the drying of the clothes, a controller operably coupled to the environmental drying sensor for controlling a drying cycle based on the sensed environmental condition, and a dispensing system for dispensing a treating chemistry to the treating chamber, the method comprising:

  • determining, by the controller, an activation or effective temperature of a treating chemistry in the dispensing system;

    heating the laundry during a heating phase to a reference temperature corresponding to the determined activation or effective temperature of the treating chemistry;

    providing an output from the environmental drying sensor to the controller indicative of the temperature of the laundry during the heating phase;

    cooling the laundry during a cool-down phase subsequent to the heating phase to a predetermined temperature; and

    comparing the output with the reference temperature and dispensing the treating chemistry to the laundry when the output satisfies the reference temperature.
