What to do if Airwell AWAU-YDD009-H11 Air Conditioner has AC over current protection?
If your Airwell Air Conditioner experiences AC over current protection, ensure the power voltage is within AC220~240V +/-10%. This issue may arise due to an unstable or too low supply voltage combined with a high load.
Why is my Airwell AWAU-YDD009-H11 Air Conditioner compressor overheating?
If your Airwell Air Conditioner's compressor is overheating, it might be due to an EEV connection problem or damage, refrigerant leakage, or poor heat exchange. To address this, confirm that the power breaker operates normally.
What causes overload of system in Airwell AWAU-YDD009-H11?
If your Airwell Air Conditioner system is overloaded, it is likely due to an abnormal system. Check if the evaporator and condenser are dirty and blocked, as the suggested solution indicates.
Why does my Airwell AWAU-YDD009-H11 show a sync failure?
If your Airwell Air Conditioner is showing a sync failure, it could be caused by abnormal power input voltage, compressor wiring mistake, liquid and gas valves not being open, damaged or improperly working EEV, poor heat exchange, or an overcharged system. Confirm that the power breaker operates normally.
What causes compressor overload protection in Airwell AWAU-YDD009-H11?
If your Airwell Air Conditioner's compressor experiences overload protection, potential causes include an EEV connection problem or damage, refrigerant leakage, or a damaged OLP. The suggested solution is to confirm that the power breaker operates normally.
What to do if Airwell Air Conditioner has EEPROM problem?
If your Airwell Air Conditioner has an EEPROM problem, replace the indoor main board.
