Internal temperature detection: check for overheating within air conditioners, clean filters and radiators to ensure good ventilation。
Detection of refrigerants: professional technicians are required to test refrigerant volumes and, if inadequate, to supplement refrigerants and repair leak sites。

Internal failure: failure of internal circuits or parts of air conditioner, resulting in normal activation。
Steps for resolution:
Wait for delay: wait a few minutes before restarting the air conditioner to see if it is properly activated。
Check the power: ensure the power pressure is stable, check the power outlets and the power lines。
