Question about LG Art Cool LA181CNW Split System Air Conditioner

1 Answer

I have a LG Artcool LAN121HNP the unit will only ciculate air (not cool) it is only 2 years old. I have had an HVAC guy look at it, he says the compressor is fine. We have put a new board in the outside unit but it will only cool when the test button on the board is pressed. He says he is not getting any signal from the inside unit, but when I switch the romote unit off the fans (both inside and outside) switch off. Could the board on the inside unit be bad.?

Make sure none of the thermostat wires from the inside unit to the outside unit have come loose or have be cut by a weed eater or such. These units are a little more complex than your average heat pump.

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.

Installed an artcool in my appartment and it constanly leaves a little puddle of water on the floor, irregardless of the temp setting or the fan speed. Drain hose is connected to the plumbing drain. Water...

first of all check the outdoor unit if it is in your reach  than simply touch both the valve & feel the temp if smaller valve is colder than the bigger one than surely the problem is with refrigerant quantity.
