Abstract: A refrigerator may include a storage part including a compressor and an evaporator and configured to store a food item at a low temperature using air cooled by the evaporator. The refrigerator may also include an ice making compartment configured to make or store ice using air cooled by the evaporator, and a fan for making ice allowing air cooled by the evaporator to flow to the ice making compartment. Additionally, a rotation speed of the fan for making ice changes while the fan for making ice continues to operate during operation of the compressor.
