SOURCE: LG window AC turns on and off by itself

We have had a similar problm and it has ended up being the energy saving light bulbs in the house, when we turn on the light switch on the energy saving bulbs they can send out a similar frequency turning on the ac unit, if you do not have the light bulbs its more than likely a fault in the pc or you have programmed the on/off timer to start the ac? hope this helps

SOURCE: Noisy indoor air conditioning units

Ok. So first things first. LG have a reputation with all their products. THEY ARE ALL BAD! If you remember GoldStar, they are now LG. GoldStar had horrible products. Now this is what LG has. The fact that the filters are cleaned and the units are serviced is an abosulte plus and will provide the units with extra longevity. Now are these drains are they used for water drainage. If so the upstairs units shouldn't need them unless there is some sort of rise in the drain pipe.

Now to the noise. It seems like there is something which is causing the fan to make a noise. It could be loose bearing or a piece of the fan which has broken away causing it to hit the inside of the unit. Since it is on both units, it would be a generic problem with this series and unfortunately is what you are stuck with now.

To combat this problem, I would: ring LG and the company who installed them and demand that they be repaired and have a warranty on the repairs. Just a heads up, LG are really bad to contact should you have a complaint, so keep persisting that they be repaired free of charge since that they are still under warranty.

If you are not happy with LG or your installers response, I would remove the units and have another brand put in. I recommend Mitsubishi Heavy Industries and Panasonic. Both units are whisper quiet. In fact they are quieter that the LG.

Oh and that only reason why LG boast about their "whisper quiet-ness" is because that is probably the only good going for them - and thats' not even right!

I hope that I have helped you in some way. Good Luck!

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: air con indoor unit is flashing 6 times out door is off

Please specify the make and model of your unit.
If this is a LG inverter model.
The six flashes of the indoor unit light indicates a CH 06 alarm.
This alarm state indicates that the indoor unit pipe temperature sensor has measured a temperature out of range or the unit is protecting itself from this low temp state. Indoor unit coil temperature to low. Should it have reached a temperature of -5°C for longer that 30sec it will switch the machine off.

It could indicate that the unit refrigerant charge is too low or the sensor has gone out of calibration.

It should measure 5kΩ @ 25°C

SOURCE: LG Ductless Mini Split System LAN125hv: Heat pump doesn't run.

First check your circuit breaker or fuse that supplies power to the outside unit. It's probably separate from the inside unit. Then try to turn unit on. If the fan and compressor just make a humming sound then turn it off and check the capacitor if you have a multimeter. You can also look at it and see if the top looks expanded. That's a good sign its bad, but not all bad one's look expanded. Tomorrow I will have access to an LG service manual and can let you know what the code means. Sorry I can't get it sooner. Let me know what you find.

Outside unit turns on and runs for a long time by itself then shuts off. Does this all day an night long. Notice this after a circuit breaker tripped. Not breaker to unit though. Other parts of house.


You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset. If you need any other Air Conditioning Repair help. Check us out online.

Air conditioner fan is blowing but not air coming


If you mean that your OUTDOOR AIR CONDITIONER FAN MOTOR is blowing AND no air is coming out of the vents within your house, it clearly indicates to me that 1 of 2 things are wrong.

Either (1) your INDOOR AIR HANDLER is NOT running or (2) the INDOOR AIR HANDLER is running but your PLENUM has come apart.

If your INDOOR AIR HANDLER UNIT is NOT running, it could simply be the circuit breaker is OFF/TRIPPED and simply needs to be turned OFF; then turned ON. If that does not FIX your problem, then it is most likely your 5 micro-farad run capacitor for your indoor fan motor needs to be replaced. It will prevent your indoor fan motor from energizing. Worst case scenario would be your INDOOR FAN MOTOR has windings burnt and needs to be replaced. If your indoor air handling unit is equipped with a CONDENSATE VALVE CUT-OFF SWITCH, check to see if your drain pan is filled, thus energizing the switch. If the CONDENSATE VALVE CUT-OFF SWITCH is ENERGIZED, it will prevent the AIR HANDLER FROM energizing. That is the design and the reason for this valve.

Good luck.

Inside motor not running and will not run on just fan. cage turns easily by hand


If the out door unit is running without the indoor fan running, you could possibly have a motor burned out or your indoor unit.
If nothing is running, check to make sure all panels are on inside, and that you have electricity to the indoor unit. Some air handlers and furnaces are equipped with a safety switch on the access door to the motor assembly. Also , there may be a switch that looks like a light switch beside the indoor unit.

Once again, check and see if the outdoor unit is running. It will eventually freeze up without the indoor fan. Hope this helps. Please email me if you have any more questions , I will try to step you through. Mark

The supply is 220v going to pcb. indoor .the outdoor unit was not working due the power supply..was 110v,, prom the pcb indoor..


I assume you are in Australia? There should be a 240v feed to the indoor unit. Once the indoor unit has been switch on , there shouldbe a 240 v supply to the outdoor unit. The communications wire will fluctuate what voltage is supplied to the outdoor. Unless you are a licenced electrician, I would not suggest you attempt to check these figures as the risk of electrocution is very high. No power to the outdoor unit can be as simple as a failed air / pipe sensor on the indoor unit , or the indoor board itself is faulty. Call up an LG Agent in your area for service and to protect your welfare..

I could not find a "fault code" list for the LA125HV but for thier Multi Split Units LG lists code CH7 (C7) as "Indoor Unit is Set in Different Cool/Heat Operation Mode." So maybe your air-handler tihinks it's in Heat mode will the compressor is in Cool mode, or vice-versa....
