Customer Question

I also have a 5 error code. Do you have a similar manual for LG LS180HSV4? It seems to be different than the one in the link you posted. The unit is only a month old. I can't believe it would be a bad wire. I used heavier gauge than what was called for. But I will run a new com wire just to check first. Thanks

The service manual link that I saw on the answer to a similar question had very specific troubleshooting steps. But it was for a unit that looked to be older and the terminal block was not the same.

Customer: replied 2 years ago.
Indoor unit shut down sometime during the night and LED light is blinking 5 times. Error code 5 appears to be a communication problem between indoor and outdoor units.

Thank you...90% of the time the issue is with the outside board. Have you checked power to the outdoor unit? Check outdoor board for any burn marks.
