Abstract: A method for controlling a linear compressor and a method for controlling a refrigerator are provided. The method for controlling a linear compressor may include measuring an ambient temperature, and when the measured ambient temperature is equal to or lower than a predetermined safety temperature, applying a safety current to a motor assembly for driving a piston. On the other hand, when the measured ambient temperature is higher than the predetermined safety temperature, a current lower than the safety current may be applied to the motor assembly.
