A refrigerator has a water tank, a pump with a motor, a current detecting part, and a controller. The current detecting part detects a motor current flowing through the motor so that the current detecting part outputs control signals like a binary of high/low level according to the detected motor current. The controller turns on/off the motor according to the control signal from the current detecting part. By this refrigerator, the existence of the water in the water tank may be detected accurately.
