Zusammenfassung:	PROBLEM TO BE SOLVED: To detect the abnormality of a fan motor causing severance of wire, lock, etc. in such the case that the number of revolutions set by the fan motor is different from the actual number of revolutions. SOLUTION: This refrigerator comprises an in-refrigeration fan motor 1 and a machine room fan motor 2 and it also comprises a controller adjusting the voltage applied to the fan motor and executing control on the number of revolutions. The controller comprises an in-refrigerator fan motor revolution number detecting means 6 for detecting the number of revolutions of the machine room fan motor 2 and a fan motor control means 7 for controlling the fan motor, and it can determine the abnormality of the fan motor from the difference between the detected number of revolutions of fan motor and the number of set revolutions.
