I have a LG hide away unit that gives me a CH code on the indoor controller

It is a reminder to clean the filter

Split System Air Conditioner Considering this, what does Ch mean on LG air conditioner? It is not a problem but it is just the reminder to clean the filter of the air conditioner. ... LG Split System Air Conditioner Error code = 05 LG AC Fault Definition = Communication(Indoor Outdoor) - Communication Issue. Indoor Status = Off.

The CH05 error message means you have an indoor / outdoor unit communication error. It can be caused by any of the following issues:

• No power on indoor unit
• Indoor/outdoor unit power connection error / communication line not installed
• Communication error caused by external noise
• Indoor/outdoor unit communication circuit parts burned.

Please give model numbers of both indoor and outdoor units!

CH 5 on these units indicates a communications error between the indoor and outdoor units. Generally, it will require a replacement outdoor board assembly to repair it. Lookup LG parts on the internet or ring them for your nearest Agent or parts. 800 243-0000

Hi sir

LP - 60
HP - 280
Both circuit
One fan motor not good
What problem

How do i fix an error 10 CH

CH-06 REFERS Indoor unit coil sensor fault. Disconnect from PCB measure resistance. 10 kOhm at 10C and 4 kOhm at 30C. if not replace sensor. THANKS.

This is a Comms error, you may have had a power spike/voltage drop/power cut. Or a wire has been broken but this is unlikely.

I would suggest turning the power off at the indoor unit by the isolator, and also the power at the outdoor unit. leave off for 10 minutes, turn on isolator on the outdoor unit and then the indoor unit. Then start the unit up.

If the problem persists you may have a fault with the unit and a A/C contractor would be required.

This is a common call for LG equipment, i get it all the time.

all the best

Communication between indoor PC and outdoor PC missed. Check that all connecting cables are good.

ch5 error code, means that there is a
communication error (serial comunication) between the outdoor and the indoor unit.
Only for LG-airconditioners.
