A refrigerator has at least one chamber, a temperature adjuster adjusting a temperature inside the chamber, a first temperature sensor approximately sensing the temperature inside the chamber, a second temperature sensor spaced from the first temperature sensor so as to sense the real temperature inside the chamber, and a controller controlling the temperature adjuster according to the temperature sensed by the second temperature sensor when the temperature sensed by the first temperature sensor is within predetermined temperature limits of the chamber and the temperature sensed by the second temperature sensor is not. With this configuration, the temperature inside the chamber is effectively controlled by an accurate and prompt sensing operation. Though one of the first and second temperature sensors is abnormal, it is possible to replace or repair the abnormal temperature sensor, or to control the temperature adjuster by the other normal temperature sensor.

An ice making mechanism includes a tray for receiving water to be frozen into ice bodies, a sensor for determining whether the water is frozen, to initiate an ice-ejecting mode, a motor for rotating the tray to perform the ice-ejecting mode, a switching mechanism for indicating a state of the ice-ejecting mode, and a switch actuating structure driven by the motor for changing a state of the switches during the ice-ejecting mode. When an ice-ejecting mode is initiated, a time period for the state of the switching mechanism to be changed is compared with a reference time period. If the state of the switching mechanism has not been changed within the referenced time period, the ice-ejecting mode is stopped, and the tray is returned to an up-right position. Also, an alarm signal is generated indicating to a user that the ice-ejecting mode has been stopped.
