  If the trouble with your Mitsubishi Electric Air Conditioner is not reoccurring but 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 matters related to wiring. After service, reset check code logs and restart the unit. Note that there may be no abnormality in the electrical components, controller board, remote controller, etc.
