LG unit, only a couple months old. Rather not deal with warranty repair. Unit is set to 75 in cool mode. Unit never stops running though. A seperate thermostat confirms room goes down to 55 degrees.
I have moved what I believe to be the thermostat sensor on the intake. I moved it to the middle of the intake so it would get lots of air, and same thing. Room has plenty of circulation so there should not be any hot spots.

replace the thermostat
of course it will not stop if the air in the room is not controlled ( doors open , window open, room to big fore the ac unit or if the temp control is set too low ( 25 c is optimum setting)
Hi, hild, first thing; stop the AC by remote controler, than select the fan option pressing by mode button and next start the AC, wait 8 minutes, if the unit still blows cold air, the thermistor has to be replaced. I hope this was helpful to you! success!
After reading over the Owner's Manual for your unit, I wonder if you are operating it in the Cool & Dry Mode. If that's the case, the dehumidifier is in operation, which would account for having to drain the unit every 2 to 3 hours. Ideally, the Cool and Dry Mode should only be operated for about an hour, when the unit is first started . Removing the humidity will allow the AC function to cool more effectively. But, it is not necessary for it to remain in Cool & Dry mode all the time. Because the AC itself unit will remove some humidity too.
Hope this helped you to troubleshoot and solve the issue of having to drain the unit every 2 to 3 hours
Disconnect power to the unit and reconnect. If "stop" is still on the display you will probably need a qualified technician to trouble shoot. The best mode is the snowflake (cooling). The rain drop is dehumidification which can cause condesation on unit.
I have the same problem. Sounds like the unit is stuck in "Dry Mode". Dry Mode runs the compressor for short intervals (like one minute at a time). Mine is only 2 months old and worked great until a few days ago.
Sounds to me like the run capacitor is bad. It is a dual one which means runs the fan and the compressor. No big deal capacitors are only 10 bucks and easy to replace.
First turn off the electricity to unit at breaker would be best. Next after you open the access panel locate the capacitor and make a note which wires go where one side is marked fan the other is herm. in the middle is comm. Take the old one in and get a new one same size and reinstall. Now parts only have one year warranty but they should have a discount on a person that bought a unit from them if you talk to them and tell them how can this happen only 2 years old. you know the story they might just throw one in for free to keep good business practice. Let me know how it goes. ken
The unit is designed to run the indoor fanmotors continuously when in cooling mode on both indoor units (evaporators). The reason is that this circulates the air and the temperature thermistor or sensor is able to sense return air temperature and in turn start or stop the outdoor unit and compressor as required according to the setpoint temperature. The reason for either unit not reaching setpoint temperature can be a couple of reasons. A) Incorrect design - the unit may be too small for the application. You can calculate this roughly at 650BTU per square meter of room in a relatively warm ambient climate. Or secondly B) The outdoor unit has leaked and is short of refrigerant. You can check this when the outdoor unit is running by feeling the thicker copper tube on the right hand side of the unit. This should be cool to cold. If no temperature difference is felt, it is short of refrigerant. Hope this helps you. Goodbye
SOUNDS LIKE THE T-STAT TEMPERATURE SENSING BULB IS OUT OF "AIR-FLOW" (SOME CAN COME LOOSE FROM THEIR MOUNTING CLIPS) OR IT IS BAD ALL TOGETHER ...
MOST MANUFACTURERS HAVE A ONE-YEAR WARRANTY ON SMALL PARTS AND 5 YEARS ON THE COMPRESSOR ..,
HOPE IT HELPED.
