  If the trouble with your Mitsubishi Electric Air Conditioner is not reoccurring but is logged, consider the possibility of temporary defects such as the activation of protection devices in the refrigerant circuit (including the compressor), poor wiring connections, or noise. Re-check the symptom, and check the installation environment, refrigerant amount, weather when the trouble occurred, matters related to wiring, etc. Reset check code logs and restart the unit after finishing service. It may also indicate that there is no abnormality in the electrical components, controller board, or remote controller.
