LG AC Error Code Solution|Inverter Air Conditioner

LG AC Error Code Solution Inverter Air Conditioner The “unit” digit of the fault code is shown by the power that has the following symbol. It is usually red, but on some models it is green. If there is a malfunction in an LG universal unit, a two-digit number will appear on the display led by the remote controllers. If the unit does not have a remote controller, the fault will be displayed using the LED in front of the indoor unit.

Error Indicator:

LG AC Error Code Solution Inverter Air Conditioner, The function provides self-diagnosis and displays error codes when there is any trouble.
Error codes are displayed as a CH **, and / or fascia display on the wired remote of the indoor unit. In addition, the code is indicated through the LED of the external unit control board.
If more than two problems occur simultaneously, a lower number of error codes are displayed first.
After the error occurs, if the error is released, the error LED is also released simultaneously. Lg Tower Air Conditioner
