Abstract: A refrigerator includes an ice maker, which includes an ice making cell, a heater configured to supply heat to the ice making cell during an ice making process, and a controller configured to control the heater. A cooling power of the cooler when a temperature sensed by a temperature sensor is greater than or equal to a limit temperature during an ice making process is greater than a cooling power of the cooler when the temperature is less than the limit temperature. A heating amount of the heater when the temperature sensed by the temperature sensor is greater than or equal to the limit temperature during the ice making process is greater than a heating amount of the heater when the temperature is less than the limit temperature.
