As described the voltage you are seeing is fake. if there is no led lighting in the indoor unit check the small transformer in the indoor unit you should get 12V DC or 24V DC out from it

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 supply is 220v going to pcb. indoor .the outdoor unit was not working due the power supply..was 110v,, prom the pcb indoor..


I assume you are in Australia? There should be a 240v feed to the indoor unit. Once the indoor unit has been switch on , there shouldbe a 240 v supply to the outdoor unit. The communications wire will fluctuate what voltage is supplied to the outdoor. Unless you are a licenced electrician, I would not suggest you attempt to check these figures as the risk of electrocution is very high. No power to the outdoor unit can be as simple as a failed air / pipe sensor on the indoor unit , or the indoor board itself is faulty. Call up an LG Agent in your area for service and to protect your welfare..

Need a manual for a LG split system


You should be able to get a service manual from the manufacturer online and down load it? Or go to where this unit was purchased and they should be able to help you.Get the model, serial, and product numbers from both indoor and outdoor units to take with you. The more info you have the better. The outdoor serial number shows the manufacture date.Have you removed the excess panel on the outdoor unit to see if a manual may be inside? they sometimes put them there instead of handing them to the owner. Good Luck!
