An operation control apparatus for a refrigerator performs a cooling operation by using a refrigerating compartment temperature regulator directly connected to a power-supply input terminal even if a freezing compartment temperature regulator is turned off, thereby effectively restricting an increase of the inside temperature of the refrigerating compartment. In an operation control apparatus for a refrigerator which includes a freezing compartment temperature regulator for setting a freezing compartment temperature to a predetermined temperature and a refrigerating compartment temperature regulator for setting a refrigerating compartment temperature to a predetermined temperature, the freezing compartment temperature regulator is serially connected to the freezing compartment fan motor, the refrigerating compartment temperature regulator is serially connected to the refrigerating compartment fan motor, and the serially connected refrigerating compartment temperature regulator and refrigerating compartment fan motor and the serially connected freezing compartment temperature regulator and freezing compartment fan motor are connected in parallel to an input terminal of a power-supply.
