An ice making machine in which upon starting of an ice making operation, a water level detecting switch starts measurement, and a water-supply-stop time T1 is compared with a reference time T2. When the water-supply-stop time T1 is not longer than the reference time T2, it is determined that the ice making machine is an excessive-ice-making state, and control is performed so as to reduce the RPM of a fan motor for cooling a condenser.
