Abstract
A home appliance and a signal output method thereof are disclosed. The home appliance outputs product information in the form of a sound signal, which is transmitted to a service center at a remote site over a communication network so that the service center can readily check the state of the home appliance. A digital signal including product information of the home appliance is converted into a sound signal based on a plurality of frequency signals. Therefore, a larger amount of data can be rapidly transmitted for a fault diagnosis, so as to improve fault diagnosis accuracy.
