To Next PageTo Next PageWhat to do if the trouble is reoccurring on my Mitsubishi Electric PUZ-SM100VKA2?
If the trouble is reoccurring on your Mitsubishi Electric Air Conditioner, judge the problem and take a corrective action according to “9-3. SELF-DIAGNOSIS ACTION TABLE”. Conduct troubleshooting and ascertain the cause of the trouble according to “9-4. TROUBLESHOOTING OF PROBLEMS”.
What to do if the trouble is not reoccurring on my Mitsubishi Electric PUZ-SM100VKA2 Air Conditioner?
If the trouble with your Mitsubishi Electric Air Conditioner is not reoccurring, consider temporary defects such as the work of protection devices in the refrigerant circuit including compressor, poor connection of wiring, or noise. Re-check the symptom, and check the installation environment, refrigerant amount, weather when the trouble occurred, and matters related to wiring. Reset check code logs and restart the unit after finishing service. If all else fails, there is no abnormality in electrical component, controller board, remote controller, etc.
What to do if the trouble is not logged on my Mitsubishi Electric PUZ-SM100VKA2?
If the trouble is not logged on your Mitsubishi Electric Air Conditioner, re-check the abnormal symptom. Conduct troubleshooting and ascertain the cause of the trouble according to “9-4. TROUBLESHOOTING OF PROBLEMS”. If the cause is not ascertained, continue to operate unit for the time being. If all else fails, there is no abnormality concerning of parts such as electrical component, controller board, remote controller, etc.
