Sounds like you have poor insulation in that room or the unit is undersized for the room it is cooling. It should not get hot quickly is there is good insulation and is big enough to do the job. Since you do not mention the age of your home/room or the size of the room, I can't be more specific. The number of turns may or may not be an issue. Depends of which of the lines are taking all the turns. Are the lines insulated? If they are overly long this could take longer to cool down but not much else if the system in full of Freon. If you do not feel cold air coming out of the unit at all and the compressor is running then check the air filter. If it is the littlest bit dirty and the unit is undersized for the room then any restriction would make it even more ineffective.

SOURCE: LG split (3 indoor) LMU360CE

The LED #2 is only flashing while in disconnection or short in Thermistor (3 sec off / 0.5 sec on). If you want to change it, note: this is not an easy job to do! You will need to remove the top panel, then remove the control paneland then the front panel to gain access to the thermistor. The part isnot available to the public and requires an authorized service techfrom LG to take care of this problem. You will need a special tool toremove the front door seal spring clamp.
But you can call customer service @ 800 243 000 and see if theycan transfer you over to parts. Just give them the model and serial #and see if they would be willing to sell you the thermistor part. Youwill also need the door seal spring clamp removal tool to make the jobeasier.

SOURCE: Hi. I recently installed 1.5 T, 3 * Split AC, LG.

Hello

Sounds like the compressor is shuting down on high heat.There could be a couple reasons for this.
1 Check that proper voltage is being supplied to compressor.
2 Freon level may be low.This would be a service call.
3 Bad or intermitent connection at thermostat.
4 Main contacts to compressor sticking,usually burnt or pitted.

SOURCE: AC Starts normally but after some time of coolinf

Probably overheating. Check the outdoor coil and see if it is stopped up with dust, grass etc. If so, disconnect power to the unit, and clean the condenser coil with water or air. Be careful not to bend the fins if you use a water sprayer.

My wall split a/c 24000 btu work about 1 hours or more after no cooling and u can see frost in the indoor coil and on the coppers on out door unit and i have low pressure 40


Low pressure and frost on your indoor coil with the copper pipe to your outdoor unit is almost guaranteed a low refrigerant charge. It can also be a bad metering device. You will need to check you high and low side pressures to be sure and make sure you let the frost thaw before checking pressures.

Mistral mss 1.0kw unit - When switched on the indoor unit & the outdoor compressor runs normally but the air coming out of the blower is not cool even after a long time. Is there a reset button to...


If the indoor unit blower is running and the outdoor unit fan is turning, you will need to make sure that the compressor itself is actually running and that it is not just the outdoor fan that is turning.
Get close and listen to the end of the unit were the compressor is located, also carefully feel the two copper lines, where they connect to the outdoor unit, they can be very hot - if working properly, so be careful.
There is no reset button that is easy to get to, the limits are usually auto resets, I would hazard a guess that the system is low on refrigerant and will require a HVAC tech.
But before that, make sure that the coils / fins on the outdoor unit are clean and not plugged with leaves, grass, cottonwood, ect.
You can turn power off to the unit and carefully wash the coil out with a garden hose, do not use a nozzle, as the higher water pressure can bent the fins.
As the water runs thru and drains off of the coil, watch and see if it is very dirty, rinse till the water is clean.
Restore power to the unit and try it, If it still does not work, the unit might be low on freon or the safeties might have been already damaged.
Once the unit is repaired, in the future make sure and keep the coil rinsed and free of any blockages.

Split unit, I get heat but no cold


I have run into this with the LG brand systems. try shutting power off to the outdoor unit to reset all units. If problem persists, it could have to do with a charge level of refrigerant (freon) or possibly a failed control board.

It sounds like you have lost communication between the indoor and outdoor units. This can be one of two things. Either the connection indoor or outdoor is loose or bad, or a rat may have eaten the cable in cieling.

This can only be a gas problem.

Good luck.

Lg split indoor fan runs non stop


Hello Hamid,
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
