Abstract: The present invention relates to a refrigerator and to an apparatus and method for refrigerator diagnosis. More particularly, the refrigerator converts product information and outputs a tone when a command for storing data and performing a diagnosis is inputted during operation. The refrigerator diagnosis apparatus receives the tone and diagnoses the state of or presence of defects in the refrigerator based on the data contained in the product information so as to analyze the cause of the defect and propose countermeasures to repair the refrigerator. Thus, the diagnosis of defects may be accurately and easily performed upon the occurrence of defect in the refrigerator.

Abstract: Provided are a refrigerator and a diagnostic system for the same. The refrigerator includes a selection unit, a control unit, a modulator, and a sound output unit. The selection unit receives a diagnosis performance command. The control unit generates a control signal including product information when the selection unit receives the diagnosis performance command. The modulator generates a frequency signal according to the control signal generated by the control unit. The sound output unit outputs a sound including the product information according to the frequency signal generated by the modulating unit.

Abstract: An apparatus is provided for controlling a lamp of a refrigerator. The apparatus may include a dispenser provided on a refrigerator door and a lamp installed within the dispenser for illuminating the dispenser. The dispenser may include a rotary member that rotates as an operation lever provided in the dispenser is operated and a duct door for selectively opening and closing an ice duct. The rotary member may include a rotary shaft supported by side walls of the dispenser and a connector part that extends from the rotary shaft. The duct door may be coupled to the connection part.

Abstract: Disclosed are an apparatus and a method for controlling lamps which are provided in a dispenser and a backlight of a manipulation button array. According to the present invention, at least one lamp is provided in the dispenser and an illumination sensor for sensing the surrounding brightness of a refrigerator or a sensor for detecting a user approaching the refrigerator is also provided. There is also provided a memory unit for previously storing a reference luminous intensity, the value of which is capable of being changed by the user. There is also provided a lamp driving unit for selectively controlling the brightness of the lamp by controlling the output signal thereof according to a driving control signal of a control unit. According to the present invention, the user can easily take ice or water from the dispenser because the lamp is turned on.
