SOURCE: LG split (3 indoor) LMU360CE
The LED #2 is only flashing while in disconnection or short in Thermistor (3 sec off / 0.5 sec on). If you want to change it, note: this is not an easy job to do! You will need to remove the top panel, then remove the control paneland then the front panel to gain access to the thermistor. The part isnot available to the public and requires an authorized service techfrom LG to take care of this problem. You will need a special tool toremove the front door seal spring clamp.
But you can call customer service @ 800 243 000 and see if theycan transfer you over to parts. Just give them the model and serial #and see if they would be willing to sell you the thermistor part. Youwill also need the door seal spring clamp removal tool to make the jobeasier.

The outdoor unit has to be powered from the indoor unit on which the main processor board is present.Disconnect power and check the main PCB. It is possible that the main unit has shut off as there is connection fault or a fault in the compressor unit. So the outdoor unit power supply from the indoor unit must be checked with a multimeter for voltage on switch on. If not there are errors in the main processor board.
