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 controller configured to:
operate the heater while the ice is being formed so that gas bubbles dissolved in the liquid within the cell move from a portion of space where the liquid that has phase-changed into the ice to another portion of the space where the liquid is in a fluid state, and
in a state in which the heater operates, when a defrosting start condition is satisfied while the ice is being formed in the space of the cell, perform a defrosting process,

wherein the heater continues to be turned on during performing of the defrosting process and the controller is configured to reduce an output of the heater.
