As shown in FIG. 5, when the inside temperature of the freezer compartment is set, the time t taken for ice making once is set, the water supply to the ice making container 33 is completed. Defrosting is started and it is determined whether a predetermined time has elapsed, and if it has elapsed according to this determination result, the ejector 22 is driven, and it is determined whether it is within the set time range by detecting the one-time ice making time. If it is within the set time range, the above operation is repeated again, and if it is not within the range, the temperature detecting unit (not shown) detects the inside temperature to determine whether it is within the set temperature range. It is determined that it takes a lot of time to supply water to (33) (that is, leaking pipe), and informs the user, and if the determination result is not within the set temperature range to the ice maker 33 By determining that there is no abnormality, the compressor (not shown) is driven, and the high temperature inside is maintained at the set temperature, so that the user can eat ice at a desired time.
