ABSTRACT:
An electric control apparatus for an ice making machine includes an initial water supply cycle control device for opening a water valve for a predetermined time, and a water level sensor mounted within a water tank for detecting whether or not a level of water in the water tank is more than a predetermined level. A first check-up device is provided for permitting operation of a defrost/water supply cycle and an ice making cycle when the level of water in the water tank exceeds the predetermined level after an initial water supply cycle is conducted under control of an initial water supply control device. The first check-up device also repeats operation at the initial water supply cycle when the level of water in the water tank is less than the predetermined level. A second check-up device permits operation of the ice making cycle when the level of water in the water tank exceeds the predetermined level after the defrost/water supply cycle, and repeats operation at the initial water supply cycle when the level of water in the water tank is less than the predetermined level after the defrost/water supply cycle.
