Abstract: A control method for a refrigerator comprises driving a first cooling fan to cool a first storage chamber; adjusting a damper to cause cold air to simultaneously flow through first and second cold-air passages; adjusting a damper to reduce the opening angle of the first cold-air passage, when the temperature of a high-temperature chamber reaches a value smaller than or equal to a second reference temperature for the high-temperature chamber; adjusting a damper to reduce the opening angle of the second cold-air passage, when the temperature of a low-temperature chamber reaches a value smaller than or equal to a second reference temperature for the low-temperature chamber; and driving a second cooling fan to cool a second storage chamber. When a predetermined time elapses or the sensed temperature of the high-temperature chamber reaches a first set temperature, the damper is adjusted to increase the opening angle of the first cold-air passage.
