Why does my Mitsubishi Electric PUHZ-SW75VHAR6 have logged errors that are not reoccurring?

If a trouble with your Mitsubishi Electric Air Conditioner is not reoccurring but is logged, it may be due to temporary defects such as the activation of protection devices in the refrigerant circuit (including the compressor), poor wiring connections, or electrical noise. To address this, consider these temporary defects and re-examine the symptoms. Check the installation environment, refrigerant level, weather conditions when the issue occurred, and wiring. After servicing, reset the check code logs and restart the unit. This indicates there is likely no abnormality in the electrical components or controller board.
