To Next PageTo Next PageWhat to do if the inferior phenomenon is reoccurring on Mitsubishi Electric Mr.SLIM PUHZ-RP1.6VHA Air Conditioner?
If the inferior phenomenon is reoccurring with your Mitsubishi Electric Air Conditioner, determine the cause and take corrective action as described in “11-4. Self-diagnosis action table”. Also, troubleshoot to ascertain the cause of the problem, referring to “11-5. Troubleshooting by inferior phenomena”.
What to do if the inferior phenomenon is not reoccurring and is logged on Mitsubishi Electric Mr.SLIM PUHZ-RP1.6VHA?
If the inferior phenomenon with your Mitsubishi Electric Air Conditioner is not reoccurring but is logged, consider temporary defects such as the activation of protection devices in the refrigerant circuit (including the compressor), loose wiring connections, or electrical noise. Re-check the symptom, and check the installation environment, refrigerant amount, weather when the inferior phenomenon occurred, and wiring. After finishing the service, reset error code logs and restart the unit. If all of these steps are completed, it is possible that there is no abnormality concerning parts such as the electrical component, controller board, remote controller, and etc.
