1. A method, comprising:

  • sensing a resistance between two conductors in a dryer bin of a clothes dryer;

    generating a pulse when the resistance is lower than a threshold resistance, a length of the pulse corresponding to a length of time that the resistance is lower than the threshold resistance;

    comparing the length of the pulse to a threshold time; and

    outputting a termination signal based on a rate of pulses that are longer than the threshold time.
