Abstract: Laundry treating appliances and methods of controlling the same to determine an end-of-cycle condition are disclosed. An example method of operating a laundry treating appliance having a treating chamber in which laundry is received for treatment, and a heated air system having a supply conduit coupled to the treating chamber and an exhaust conduit coupled to the treating chamber includes supplying heated air to the treating chamber via the supply conduit, exhausting air from the treating chamber via the exhaust conduit, repeatedly determining exhaust air temperatures of the air exhausted from the exhaust conduit, determining a windowed derivative of the exhaust air temperature values, determining a zero crossing of the windowed derivative, and initiating the termination of the supplying of heated air in response to the determination of the zero crossing.
