Abstract

A method for monitoring failure of a drum rotation system of a clothes dryer comprises acquiring a conductivity signal from the conductivity sensor of the dryer, and processing said signal in the frequency domain in order to retain a frequency spectra of the clothes tumbling process while rejecting the frequency spectra of noises and/or the like.
