  If the trouble with your Mitsubishi Electric Air Conditioner is not reoccurring and is logged, consider temporary defects such as the operation 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, and wiring. Also, reset check code logs and restart the unit after finishing service. If these steps don't reveal the issue, there is likely no abnormality in the electrical components, controller board, or remote controller.
