1. A method of diagnosis for refrigeration systems or household appliances, said method comprising the steps of:

  • (i) Detecting mechanical wave signals of the refrigeration system and of the environment near the system or household appliance, the mechanical waves comprising mechanical oscillations of the surroundings of the refrigeration system or household appliance;

    (ii) Generating a spectral signature of the vibration parameters detected in step (i);

    (iii) Assessing the operating condition of the components of the refrigeration system or household appliance;

    wherein the spectral signatures generated in step (ii) are compared with the spectral signatures relating to normal operating conditions of the refrigeration system or household appliance.
