Abstract
An electrically operated aerosol-generating system is provided, including: a heating element to heat an aerosol-forming substrate proximate to the heating element; a power supply to supply power to the heating element; and electric circuitry in communication with the heating element and the power supply, the electric circuitry including a memory and being configured to: regulate a supply of power to the heating element for a heating cycle period in response to a user input, determine a first derivative of an electrical resistance of the heating element with respect to time, determine that there is an adverse condition if the first derivative exceeds a threshold value stored in the memory during a heating cycle period at or subsequent to a predetermined time in the period, and control power supplied to the heating element or provide an indication based on whether there is an adverse condition at the heating element.
