C4 error code on LG artcool airconditioner

Our LG Artcool inverter model air-conditioner keeps on having a c4 error code on it. the manual does not have any info on it whatsoever. The air that comes out of the air-conditioner is not cool and the part of the air-conditioner outside does not run at all. Any ideas would be appreciated

How too solve daikin error code c4


c4 error code has nothing to do with outdoor pcb. Use code 41 to check the value of the liquid line sensor and test with mulit meter. Pretty rare fault. Turn the power off for 5
Mins and reboot your system.

LG Artcool about 4 yrs old error code CH 05. no heating or cooling. cheers.


CH 5 on these machines indicates a communications error between the indoor and outdoor units. Generally, it will require a replacement outdoor board assy to repair it. Lookup LG parts on the internet or ring them for your nearest Agent or parts stockist.
