What to do if my LG Air Conditioner doesn’t operate at all?
- IIan NicholsAug 5, 2025
If your LG Air Conditioner isn't operating, first, turn off the main power and wait for the LED on the outdoor PCB to switch off. Then, turn the main power back on. Also, check the connecting state of wires and connectors, the diagram wiring on the control panel, and the main power supply. Verify the Fuse of the outdoor PCB assembly, and confirm the Auto Addressing work method. If problems persist, consider replacing the PCB assembly. You can also refer to the self-diagnosis function.
