Abstract
A temperature controller and method of controlling temperature for use in a refrigerating device includes a temperature sensor for detecting temperature in a compartment of the refrigerator, a conversion element, a refrigerating cycle driving element, a comparison element, and a memory element. The conversion element converts the temperature detected by the temperature sensor into a voltage value. The refrigerating cycle driving element operates a refrigerating cycle to cool the compartment in accordance with the voltage value. The comparison element compares the voltage value with a predetermined voltage range. This predetermined voltage range is wider than a voltage range corresponding to an ordinary operating temperature range at which the temperature in the compartment is maintained. When the voltage value converted from the temperature detected by the temperature sensor is outside the predetermined voltage range, it is decided that the failure has occurred in the temperature sensor, and the failure of the temperature sensor is memorized in the memory element.
