<P>PROBLEM TO BE SOLVED: To provide a refrigerating device having an electric heater for defrosting, which, in particular, detects the presence or absence of abnormality in the electric heater for defrosting with high accuracy in a simple and inexpensive equipment configuration. Ž<P>SOLUTION: The electric heater for defrosting is disposed in a cooling chamber having an evaporator, a resistor having a prescribed electric resistance value is connected with the electric heater for defrosting in series, a temperature sensor is disposed near the resistor, a temperature raised by the resistor in the defrosting operation is detected by the temperature sensor, and the detected temperature is compared with a reference temperature in a normal defrosting operation. Thus the presence or absence of the abnormality of the electric heater for defrosting is detected. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
