      If your LG Air Conditioner isn't starting, there are several things to check. First, examine the power supply: ensure the over-current protection device is working, the fuse isn't disconnected, and try resuming power to the unit. Also, verify the device configuration and wiring are correct. If an alarm is active, check the alarm condition, follow the troubleshooting process for alarms, and check the HMI input channel for alarm condition input. Finally, verify that the compressor has not entered a start delay time.
