How to troubleshoot LG Air Conditioner that does not start?
- MMatthew KingAug 20, 2025
If your LG Air Conditioner isn't starting, first ensure it's fully plugged into the outlet. Then, check your house's fuse or circuit breaker box and replace the fuse or reset the breaker if needed. If a power failure occurred, turn the mode control to off, and wait 3 minutes after power is restored before restarting to protect the compressor. Also, check the current interrupter device by pressing the RESET button on the power cord plug. If ‘FL’ appears in the display, it means the water collection tank is full; drain it and reset your settings.
