An intrabox temperature display device converts a signal representing an intrabox air temperature detected by a molded temperature sensor placed in the intrabox of a refrigerator into a digital signal by means of an A/D converter. The intrabox temperature data detected having a succession of samples with given sampling periods is stored in a memory. The intrabox temperature data read out from the memory is averaged in an operation circuit. The averaged temperature data is displayed by a display section as the temperature data approximate to a real temperature for cooling or freezing foods in the refrigerator.
