摘要： To provide a self-diagnosing apparatus for a refrigerator which self-diagnoses an operation condition and advises a user of an appropriate improvement action if there is an abnormal condition, first, detecting means such as the inside temperature sensor 1 detect a plurality of condition-indicative quantities with respect to the refrigerator, and the condition-indicative quantities are stored in the memory part 7 for a predetermined period. Diagnosis means such as the diagnosis calculation value judging part 10 compare the condition-indicative quantities or a diagnosis calculation value which is calculated based on the condition-indicative quantities with a predetermined threshold value, and judges whether the operation condition of the refrigerator is normal or abnormal based on a result of the comparison. At this stage, if the condition-indicative quantities covering the predetermined past period which are stored in the memory means are used as the condition-indicative quantities for the diagnose, it is possible to accurately diagnose without influence of a condition-indicative quantity which suddenly appears. When it is judged that there is an abnormal condition as a result of the diagnosis, an improvement action which is preliminarily determined for the abnormal condition is selected. The selected action is displayed visually or as a sound by the outputting means such as the sound outputting part 14. Where a re-diagnosis is executed after a predetermined time since the abovementioned diagnosis and the outputting means output the improvement action based on a result of the re-diagnosis, it is possible to diagnose with an enhanced reliability.
