To Next PageTo Next PageWhat to do if the Mitsubishi Electric MXZ-5C42NAHZ Air Conditioner trouble has reoccurred?
If a problem with your Mitsubishi Electric Air Conditioner keeps happening, determine the cause and take corrective action as described in section “8-3 SELF-DIAGNOSIS ACTION BY FLOWCHART”. Also, troubleshoot to find the cause of the issue, referring to section “8-4. TROUBLESHOOTING BY INFERIOR PHENOMENA”.
What to do if the Mitsubishi Electric MXZ-5C42NAHZ Air Conditioner trouble is not reoccurring?
If the trouble with your Mitsubishi Electric Air Conditioner is not reoccurring, consider temporary issues like protection devices activating in the refrigerant circuit (including the compressor), loose wiring, or noise. Re-examine the symptoms, installation environment, refrigerant level, weather conditions when the problem occurred, and wiring. Reset check code logs and restart the unit after finishing service. There may be no abnormality concerning parts such as the electrical component, controller board, remote controller, etc.
What to do if the Mitsubishi Electric MXZ-5C42NAHZ trouble is not logged?
If the trouble with your Mitsubishi Electric Air Conditioner is not logged, re-check the abnormal symptom. If the cause isn't clear, keep using the unit for now. Troubleshoot and find the cause of the issue according to “8-4. TROUBLESHOOTING BY INFERIOR PHENOMENA”. There may be no abnormality concerning parts such as the electrical component, controller board, remote controller, etc.
