PURPOSE: A controlling method of a fan in a refrigerating chamber is provided to improve cooling speed of a refrigerating chamber by resetting a driving on/off point of a refrigerating chamber sensor at initial operation of a refrigerator or when inputting overload. CONSTITUTION: A temperature sensed in a temperature sensor of a refrigerating chamber is decided to be a certain weak cooling sensing point or not. If the temperature is over the weak cooling sensing point, the driving on/off point is reset and operation is performed by high speed cooling mode. If the temperature is under the weak cooling sensing point, an R fan is decided to be driving or not. If the R fan is not driving, the on point of an R sensor is decided. If the point is driving on, the R fan is driven. If the R fan is driving, the driving off point of the R sensor is decided. If the point is driving off, the driving of the R fan is turned off. If the temperature is over 6°C, the refrigerating chamber starts to be operated by high speed cooling mode.
