My LG AC unit does not operate properly
My LG AC unit does not operate properly
If your LG-equipped Airzone installation is not operating properly, run the following checks:

Check that all the earth connections are connected in both the indoor unit and the Airzone main control board. In addition, check that the voltage between neutral and earth is 0 V. If there is voltage in the earth connection, the earthing must be improved for the system to operate properly.

Ensure that the toroid is connected to the indoor unit. To do so, check that the connection between the gateway and the AC unit is as shown in the image.

To eliminate any possible electromagnetic noise, flip up microswitch 2 on the LG gateway.
