Troubleshooting Using Error Codes
Refer to the tables below and on the next pages for error codes that
are generated from the indoor and outdoor units. These codes indi-
cate different types of unit failures, assist in self-diagnosis, and are
the most common that will manifest themselves on the LEDs. Error
codes are displayed on indoor unit LEDs, wired remote controllers,
the outdoor unit PCB, and through LG Monitoring View (LGMV)
diagnostic software.
Systems could generate additional codes not listed here. Contact LG
Support if these types of errors are seen and a simple power down
and boot up has not corrected the issue.
Do not attempt to fix
the system yourself.
• If two or more errors occur simultaneously, the highest error code
number is displayed first.
• After the error is corrected, the error code will cease to display
without user intervention.
Decoding the Error Display
See images and table below for indoor unit error codes, location of
LEDs, and operation status.
The first and second number on the LED indicates error number. Ex-
ample: 21 = LED1 (Red light) 2x blink, LED2 (Green light) 1x blink.
