Claim 20:
21. A refrigerator comprising:
a storage chamber;
a cooler configured to supply cold air into the storage chamber; and
an ice maker comprising:
a tray having a first portion and a second portion of a cell, the second portion being movable relative to the first portion, and the first portion and the second portion being configured to define a space formed by the cell to receive a liquid to be phase-changed to form ice;
a heater provided to supply heat to the cell while the ice is being formed in the cell, and
a temperature sensor configured to sense a temperature within the space of the cell,

wherein, when a defrosting process starts while the heater is turned on in connection with forming the ice in the space of the cell, a heat output of the heater is maintained when the temperature sensed by the temperature sensor is less than a reference value during the defrosting process, and the heat output of the heater is reduced when the temperature sensed by the temperature sensor is greater than or equal to the reference value during the defrosting process.
