Question about LG Heating & Cooling
Hi, i've just moved into a house with a LG ART COOL C24AWR N80 inverter unit in it. Have just tried to get it to work and it is coming up with the code CH05 when trying to get the heating to work, what is involved in fixing this issue. Regards Nigel.
Fault Code 05 This fault code indicates a communication error between the indoor and outdoor units; this is usually caused by wiring errors or condensate pumps connected to the inter-connecting cable. The communication between the units is a fluctuating DC voltage commonly called a serial signal, it can be easily lost if the wiring is not done correctly. If there is a communication error fault CH05 will appear within 5
mins of powering up the system.

Multi Splits and Multi V = indoor unit is set to run in a different mode from the master indoor unit. Set ALL indoor units to cooling or ALL to heating to clear.
Splits = Compressor Over Current (CT2)

SOURCE: I have an LG Art
The remote is fine, the batteries are new, the remote is giving signal.The remote is not communicating with the AC.On the split system front panel.There is a sensor in the internal side of the panel.This sensor detects the signal from remote.But if this sensor is weak or got faulty, then unit will work manually but not function as per remotes command.The front panel has to be removed by local ac repair tech and the panel sensor has to be checked.May be that sensor is got dirty or dust got covered on it or its got internally short.That has to be checked and confirmed.---------- But still if you have not tried with new brand battery, then before doing any thing just try with new brand battery and re-confirm that its not battery related issue.-------- --------------- This should help.Thanks.Helpmech.
