An apparatus for a refrigeration system comprising: a fan; and a motor assembly coupled to the fan and configured to: rotate the fan at a first speed during a refrigeration mode; rotate the fan at a second speed for a first period of time and at a third speed for a second period of time during a stir-cycle mode; wherein: the second speed is slower than the first speed; the third speed is slower than the second speed and the third speed is zero rotations per minute; and electric power is supplied to the motor assembly throughout the refrigeration mode and the stir-cycle mode; and wherein the motor assembly comprises a housing and a processor disposed within the housing; and the processor is configured to: determine whether the motor assembly should be operating in the refrigeration mode or the stir-cycle mode, the stir-cycle mode being a mode in which power is not cut to the motor assembly; and change the speed at which the motor assembly rotates the fan based on the determination whether the motor assembly should be operating in the refrigeration mode or the stir-cycle mode; determine, during the stir-cycle mode, that the motor assembly has rotated the fan at the second speed for the first period of time; in response to the determination that the motor assembly has rotated the fan at the second speed for the first period of time, instruct the motor assembly to rotate the fan at the third speed for the second period of time; determine, during the stir-cycle mode, that the motor assembly has rotated the fan at the third speed for the second period of time; and in response to the determination that the motor assembly has rotated the fan at the third speed for the second period of time, instruct the motor assembly to rotate the fan at the second speed for the first period of time. a fan;
