Abstract: PURPOSE:To prevent an irregular operation from occurring in the case of a rotational error by a method wherein a transistor in a pan motor driving circuit is turned OFF when a position sensing switch does not detect it within a predetermined time that an ice making pan has returned back to its horizontal position. CONSTITUTION:In the case that a temperature sensing sensor 45 detects a temperature more than an ice making completion temperature, an ice making pan 40 is reversed by a pan motor 52 from its horizontal state in which an opening is directed upward so as to remove ice blocks.
