Abstract
A system and method for diagnosing a home appliance are disclosed. The home appliance outputs product information as a sound signal, and transmits the sound signal over a communication network, such that a service center of a remote site easily checks a status of the home appliance. The home appliance outputs the sound signal including a large amount of product information, and the diagnostic server of the service center diagnoses a status of the home appliance using a large amount of product information contained in the sound signal, such that it recognizes a detailed cause of a fault of the home appliance and greatly increases the diagnosis accuracy.
