Abstract: A refrigerator configured to detect excessive condensation in a condenser based on a temperature difference between evaporators provided in each storage compartment, and configured to control an operating time of a heat dissipation fan configured to cool the condenser, and a control method thereof are provided. The refrigerator includes a plurality of storage compartments, a plurality of evaporators arranged in series with each other and provided to correspond to each of the plurality of storage compartments, a compressor configured to compress a refrigerant evaporated by the plurality of evaporators, a condenser configured to condense the compressed refrigerant, a heat dissipation fan configured to cool the condenser, a plurality of evaporator temperature sensors configured to detect a temperature of each of the plurality of evaporators, and a controller configured to determine whether excessive condensation occurs in the condenser based on a temperature difference between the plurality of evaporators, and configured to control an operating time of the heat dissipation fan based on whether the excessive condensation occurs or not.
