Abstract
An electrically operated aerosol-generating system is provided, including: a heating element configured to heat an aerosol-forming substrate proximate to the heating element; a power supply; and electric circuitry in communication with the element and the power supply, and configured to regulate the supply of power during a plurality of discrete heating cycles in response to user inputs, determine a maximum electrical resistance of the heating element during each heating cycle, calculate a rolling average value of the resistance for n preceding heating cycles, n being an integer greater than 1, compare the resistance with the calculated value, determine an adverse condition when the resistance is greater than the calculated value by more than a threshold value, the threshold value being stored in the memory, and control the power supplied based on whether there is the adverse condition or to provide an indication based on whether there is the adverse condition.
