In an ice making machine having an evaporator unit formed therein with a multiplicity of individual freezing cells and provided thereon with an evaporator in thermal exchange relationship with the freezing cells to freeze water circulated into the freezing cells during a freezing cycle, an electric control apparatus for the ice making machine is arranged to ascertain a frequency of an electric power supplied to the machine, to detect an actual freezing temperature of the evaporator unit, to determine an optimum freezing temperature necessary for complete freezing of all the water in the freezing cells in operation under the power supply of the ascertained frequency, to maintain the freezing cycle until the actual freezing temperature becomes lower than or equal to the optimum freezing temperature and to terminate the freezing cycle and initiate a harvest cycle for discharge of formed ice cubes from the freezing cells when the actual freezing temperature has become lower than or equal to the optimum freezing temperature.
