If the trouble with your Mitsubishi Electric Air Conditioner is reoccurring, you should determine the cause and take corrective action according to the self-diagnosis action table. Additionally, conduct troubleshooting to ascertain the cause of the issue, referring to the troubleshooting guide for inferior phenomena.
What to do if the Mitsubishi Electric PKA trouble is not reoccurring?
If the trouble with your Mitsubishi Electric Air Conditioner is not reoccurring, consider 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, installation environment, refrigerant amount, weather conditions when the problem occurred, and wiring. Reset error code logs and restart the unit after servicing, assuming no abnormalities are found in the electrical components, controller board, or remote controller. Re-check the abnormal symptom. If the cause is not ascertained, continue to operate the unit for the time being, assuming no abnormality concerning parts such as electrical components, controller board, or remote controller.
