hi there..same issue for my ac as well.. all wires are fine... ac works for few mins, and then ch 5 erro comes up.. sometimes ac works without any issues, but then the next day, sane error pops up.. what couls be the issue? and today its been 3 days i havent used the ac..its not starting at all
Greetings Check the input circuits at the indoor PCB make sure they are ok you may have a blown fuse once you figure out with the current problem that you mentioned your AC is off at all not starting After you are able to run the unit connect a single wire to the 3c circuit in indoor and the other end of wire should reach to the outdoor connect it to the 3c circuit of outdoor this wire should be isolated from the rest of wire Run the AC unit and wait 20 mins if the erro comes back then you need to check the PCB board at the outdoor there are so many component you have to check sometimes the PCB itself goes bad
Hi, you found the problem yet? I have the exactly issue like you. I haven't checked the wire yet. Ch05 shown up occasional after 30 min or so. After I turned off everything for any hour or so, it will be back to normal, depending on luck.
Dear James Thank you for chosen DIY & Fix it , The ground/ earth wire is for our safety and also for your AC unit. Fault Code 05 and 53 (CH05 is displayed at indoor unit, 53 is displayed at outdoor unit) 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. 01) make sure isolate your AC cable from refrigerant pipes and other cables. 02) 3c circuit in indoor is a signal circuit it's going to be connected to the outdoor make sure it is not next to the other cables or wires which is generating noise. 03) check the PCB board at the indoor and outdoor make sure all components are Ok.
Hiii Sir, gd evening I'm shakir Alam, i wanna ask u one thing.i find same issue in my Dual inverter lg Ac ch 05 i cheaked All wire connection and voltage still.issue not resolved.wht kind i do
Greetings Dear Shakir sorry for didn't reply on time, I have been working somewhere didn't get time to be active in social media but I'm happy share my experiences with my followers even if it is late but I'm pretty sure It's gonna help. (Sometime communication errors occurs due to a blown fuse in the PCB board at the outdoor unit, It is a 15 Amps fuse , replace the fuse and run the air conditioners use an ampere meter the current should not exceed more than 6.5 A @ 220 V if the unit is 12000 btu If the ampere meter shows 8 or 9 Amps you may have other issues you need to check compressor's current . You may have a bad compressor or may not, you need to troubleshoot there are so many reasons for that , I wish to get time make another youtube video on this topic. All the best
Greetings If you have already check the wires : L N 3c Ground The next step is to check all components at the PCB in the outdoor unit if everything looks good at the outdoor next check the PCB board at the indoor units.
Check the pcb board at the outdoor you may have a malfunction component also check the main board at the indoor unit Note at the outdoor unit the pcb board has a fuse check make sure it is not blown.
Same error ch 05 but it works during day time for morethan 2hours but in evening and night it runs only for few minutes then shows ch05 error What to do? Can share ur phno or address if you are technician thanks
Greetings Let me share the most terrible experience, I had the same issue with one of the AC unit , it works well daytime at night error ch05 I decided to detach the outdoor cover I found a thousands ants was sticking on the units circuit. Try to check that Immediately after the error occurs. Meanwhile check your voltage and frequency too. I'm in south Sudan I don't think so can see you physically.

Good job bro.
Thank you
Thanks to you My dear ❤
You are so welcome!

Check the input circuits at the indoor PCB make sure they are ok you may have a blown fuse once you figure out with the current problem that you mentioned your AC is off at all not starting
After you are able to run the unit connect a single wire to the 3c circuit in indoor and the other end of wire should reach to the outdoor connect it to the 3c circuit of outdoor this wire should be isolated from the rest of wire
Run the AC unit and wait 20 mins if the erro comes back then you need to check the PCB board at the outdoor there are so many component you have to check sometimes the PCB itself goes bad

Can Grand wire not be connected cause CH05 error to occur?
Dear James
Thank you for chosen DIY & Fix it ,
The ground/ earth wire is for our safety and also for your AC unit.
Fault Code 05 and 53 (CH05 is displayed at indoor unit, 53 is displayed at outdoor unit) 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.
01) make sure isolate your AC cable from refrigerant pipes and other cables.
02) 3c circuit in indoor is a signal circuit it's going to be connected to the outdoor make sure it is not next to the other cables or wires which is generating noise.
03) check the PCB board at the indoor and outdoor make sure all components are Ok.

great
what if the wire is good yet the communication is signal
Greetings
If you have already check the wires :
L
N
3c
Ground
The next step is to check all components at the PCB in the outdoor unit if everything looks good at the outdoor next check the PCB board at the indoor units.
I have the same issue i have checked the wire and is ok please what else can i do to resolve this issue
Check the pcb board at the outdoor you may have a malfunction component also check the main board at the indoor unit
Note at the outdoor unit the pcb board has a fuse check make sure it is not blown.
1mm is in lg manual
Hi there
Yeah it has been recommended to use 1mm cable but it depends on distance and quality of the cable.
nice
Same error ch 05 but it works during day time for morethan 2hours but in evening and night it runs only for few minutes then shows ch05 error
What to do?

Hello boss I from Ghana 🇬🇭 my LG Ac giving me CH05 too
Did you get it resolved?
