New KFR-51LW Air Conditioner, during the test, the power light went out immediately after it lit up.
Analysis and Detection: The voltage was measured to be 165V at the moment of startup, while the voltage of the power socket was measured as 220V. After a comprehensive inspection, it was found that the wire diameter of the air conditioner's power line was too thin at 1mm².
Repair Method: After installing a 2.5mm² core power line, the fault was eliminated.
Warm Reminder: When testing newly installed air conditioners, if you encounter the phenomenon where the power light turns on and then immediately off upon startup, it is often due to the power line being too thin or the leakage current capacity of the circuit breaker being too small, failing to meet the working current requirements of the air conditioner.
