Abstract: A method for controlling a refrigerator of the present invention includes turning on the heater when ice making is completed; moving the second tray to a standby position in a forward direction when the movement condition of the second tray is satisfied; turning off the heater when a turn-off condition of the heater is satisfied after the second tray moves to the standby position in the forward direction; determining whether the heater is turned off and a predetermined time has elapsed; and moving the second tray to the ice separation position in the forward direction when it is determined that the predetermined time has elapsed.

Abstract: Provided is a refrigerator. The refrigerator may include a first tray assembly defining a portion of an ice making cell and a second tray assembly defining another portion of the ice making cell. The refrigerator may further include a pusher provided with a first edge on which a surface configured to press one or more of the first and second tray assemblies is disposed to easily separate the ice from the tray assemblies, a bar extending from the first edge, and a second edge disposed at an end of the bar. At least one of the pusher or the second tray assembly may move so as to change a relative position between the pusher and the second tray assembly.

Abstract: A refrigerator of the present disclosure turns on a heater, which supplies heat to an ice making cell, in at least partial section while a cooler supplies cold to the ice making cell so that bubbles dissolved in the water within the ice making cell moves from a portion, at which the ice is made, toward the water that is in a liquid state to make transparent ice. A defrosting process may be performed when a defrosting start condition is satisfied in a state in which the heater is turned on. In this case, the amount of cold supply of the cooler in the defrosting process can be reduced more than the amount of cold supply of the cooler before the defrosting start condition is satisfied.
