PROBLEM TO BE SOLVED: To enable an immediate shift to a normal operation when an abnormal condition of a refrigerator is eliminated.SOLUTION: A refrigerator includes: a refrigeration cycle including a compressor 21; temperature detectors 11, 12 detecting a temperature at a specified part of the refrigerator; and a micro computer 5 serving as an operational state determination device for determining the operational state of the refrigerator on the basis of a detection temperature of the temperature detectors 11,12. Furthermore, the micro computer 5 serves as an abnormality detection device for detecting occurrence of an abnormality in the temperature detectors 11,12 or the micro computer 5 itself. When occurrence of an abnormality in the temperature detectors 11,12 or the micro computer 5 is detected, the micro computer 5 is separated from the power circuit 2 by operating a switch 32 and an emergency operation circuit 31 is connected to the power circuit 2 so as to enable an emergency operation of the compressor 21 by the emergency operation device 30 without regard to a determination by the micro computer 5.SELECTED DRAWING: Figure 1 |
