PROBLEM TO BE SOLVED: To provide a compressor motor control device for a refrigerator capable of adjusting a ratio of a cooling period in hysteresis control while dispensing with information acquisition on the cooling period. ! SOLUTION: In a compressor motor control device for a refrigerator in which hysteresis control of an inside temperature is implemented by mixing a stopping action in a heat radiation period and an operating action in a cooling period on the basis of binary information of upper limit value temperature information and lower limit value temperature information, a heat radiation period calculation processing for calculating a heat radiation period, a temperature change speed calculation processing for calculating a parameter relating to a temperature change speed on the basis of the heat radiation period, and a rotating speed setting processing for specifying information relating to a set rotating speed of a compressor motor on the basis of the parameter, are functioned. !
