If the failure diagnosis is interrupted, the failure determiner has a restarting function to restart the failure diagnosis from an intermediate point of the failure diagnosis. ## Claims ### Claim 1 A container refrigeration apparatus including a refrigerant circuit, the apparatus comprising: a non-volatile memory; and a failure determining processor configured to perform a failure diagnosis to successively evaluate in a predetermined sequence a plurality of evaluation items, the plurality of evaluation items including a first type which evaluates functioning of individual components of the container refrigeration apparatus and a second type which evaluates functioning of a combination of the individual components, and store, in said non-volatile memory, data associated with progress of the failure diagnosis, wherein the first type of evaluation items are evaluated prior to the second type of evaluation items, and if the failure diagnosis is interrupted due to a loss of power from a power supply of the container refrigeration apparatus, the failure determining processor is configured to restart the failure diagnosis from an intermediate point of the failure diagnosis based on the stored progress data. ### Claim 2 (depends on 1) The container refrigeration apparatus of claim 1, wherein the failure determining processor is configured to restart the interrupted failure diagnosis from a beginning of an evaluation of one of the plurality of evaluation items, an evaluation of which was interrupted. ### Claim 3 (depends on 2) The container refrigeration apparatus of claim 2, wherein the failure determining processor is configured to restart the interrupted failure diagnosis from an intermediate point of an evaluation of one of the plurality of evaluation items, an evaluation of which was interrupted. ### Claim 4 (depends on 3) The container refrigeration apparatus of claim 3, wherein if an evaluation of a first type of evaluation item is interrupted, the failure determining processor is configured to restart the failure diagnosis from the evaluation of the first type of evaluation item. ### Claim 5 (depends on 3) The container refrigeration apparatus of claim 3, wherein the failure determining processor is further configured to check the progress data stored in said memory, after being started, to identify any evaluation items that have not been evaluated yet, and perform evalutaion of the identified evaluation items. ### Claim 6 (depends on 2) The container refrigeration apparatus of claim 2, wherein if an evaluation of a first type of evaluation item is interrupted, the failure determining processor is configured to restart the failure diagnosis from the evaluation of the first type of evaluation item. ### Claim 7 (depends on 6) The container refrigeration apparatus of claim 6, wherein the failure determining processor is further configured to check the progress data stored in said memory, after being started, to identify any evaluation items that have not been evaluated yet, and perform evaluation of the identified evaluation items. ### Claim 8 (depends on 2) The container refrigeration apparatus of claim 2, wherein the failure determining processor is further configured to check the progress data stored in said memory, after being started, to identify any evaluation items that have not been evaluated yet, and perform evaluation of the identified evaluation items. ### Claim 9 (depends on 1) The container refrigeration apparatus of claim 1, wherein the failure determining processor is configured to restart the interrupted failure diagnosis from an intermediate point of an evaluation of one of the plurality of evaluation items, an evaluation of which wass interrupted. ### Claim 10 (depends on 9) The container refrigeration apparatus of claim 9, wherein if an evaluation of a first type of evaluation items is interrupted, the failure determining processor is configured to restart the failure diagnosis from the evaluation of the first type of evaluation item. ### Claim 11 (depends on 9) The container refrigeration apparatus of claim 9, wherein the failure determining processor is further configured to check the progress data stored in said memory, after being started, to identify any evaluation items that have not been evaluated yet, and perform evaluation of the identified evaluation items. ### Claim 12 (depends on 1) The container refrigeration apparatus of claim 1, wherein if an evaluation of a first type of evaluation item is interrupted, the failure determining processor is configured to restart the failure diagnosis from the evaluation of the first type of evaluation items. ### Claim 13 (depends on 12) The container refrigeration apparatus of claim 12, wherein the failure determining processor is further configured to check the progress data stored in said memory, after being started, to identify any evaluation items that have not been evaluated yet, and perform evaluation of the identified evaluation items. ### Claim 14 (depends on 1) The container refrigeration apparatus of claim 1, wherein the failure determining processor is further configured to check the progress data stored in said memory after being started, to identify any evaluation items that have not been evaluated yet, and perform evaluation of the identified evaluation items. ### Claim 15 (depends on 1) The container refrigeration apparatus of claim 1, further comprising: a transmitter configured to notify a user, via telecommunication, of interruption of the failure diagnosis if the failure diagnosis is interrupted; and a receiver configured to receive an instruction to restart the failure diagnosis via telecommunication, wherein if the receiver has received the instruction to restart the failure diagnosis, the failure determining processor restarts the failure diagnosis. ### Claim 16 (depends on 1) The container refrigeration apparatus of claim 1, wherein the container refrigeration apparatus has a function to select whether or not the restarting function is available in accordance with a user's instruction entered. ### Claim 17 (depends on 1) The container refrigeration apparatus of claim 1, wherein the failure determining processor is configured to forcibly terminate an operation related to a restart in accordance with a user's instruction entered. ### Claim 18 (depends on 1) The container refrigeration apparatus of claim 1, wherein if a predetermined period of time has elapsed since the power supply of the container refrigeration apparatus turned off to interrupt the failure diagnosis, the failure determining processor is configured to forcibly terminate an operation related to a restart. ### Claim 19 (depends on 1) The container refrigeration apparatus of claim 1, further comprising: a display configured to display what number failure diagnosis is being performed after receipt of a user's instruction to start a diagnosis. ### Claim 20 (depends on 1) The container refrigeration apparatus of claim 1, further comprising: a display configured to display what number failure diagnosis is being performed after receipt of a user's instruction to start a diagnosis.
