Question about Heating & Cooling
Hi we keep getting error code c6 on the inside unit, we have tried cleaning the filter and resetting the power which helps for about 5 mins then it comes up again and stops working, you cannot turn the unit off, via remote or via the button on the side of the unit. We have 2 of these units and they both have the same error code and will not work, the manual has nothing in there about error code C6. Can you please help as the weather is becoming unbearable, do I need to call someone in. We have only had these units for about 14 mths.
thanks in advance.
Error C6 on lg cool art is common. you guy need a new CAPACITOR. cost $7.05c aud. it's 6uF 450vac.
take about less than 10min to install.
my lg model is lsz244vm-4, it's run well now.

If you live in Melbourne, call WAM Electrical in Box Hill... They came out and fixed the problem in 10 minutes, it's working perfectly now through these 40 degree days !

Product Technical Update sheet 19
Title: Fault code 06 and 22 DC Peak
Fault code 06 on RAC units is the same as fault code 22 on CAC units; this is one of
the hardest fault codes to diagnose. The fault is caused by an over current in the
inverters DC power circuit and is caused by either the inverter PCB or the
compressor having a fault. The tricky part of this fault is identifying whether it is the
compressor or the Inverter PCB which is at fault.
Please ask the engineers to check the following:
Switch off the power and disconnect the compressor leads, Check the resistance of
the compressor windings, red to blue, red to yellow and blue to yellow, the values
should all be equal and typically they should be between 1 and 5 Ohms, If not
replace the compressor. Reconnect the compressor and start the unit.
Does the compressor run?
Check supply Voltage to compressor measure from (Red to blue) then (Red to
Yellow and Blue to Yellow) AC Volts.
If the readings are not equal the PCB is at fault, if they are all equal the compressor
Check the run current of the compressor on all three phases, red, yellow and
blue, these should all be equal If not the compressor will be faulty.
Check the current drawn by the unit at the incoming power terminal to the
outdoor unit this should be no higher than the rated current on the units data
plate, If the current is high the compressor will be faulty.
Does the compressor run?
You need to check the inverter output voltages are all equal; you will need a
meter with a min max function,
Turn off the power and disconnect the leads to the compressor, Connect your
meter from (Red to blue) set your meter to record max and min Voltage AC,
Power up and Start the unit, watch the Voltage rise, Record the maximum
The inverter will stop after a few seconds and the Voltage will fall to 0 Volts
Swap the leads to measure from Red to Yellow, Measure as before, Repeat
for Blue to Yellow.
The readings of maximum Voltage should be the same for all 3 measurements if not
the PCB is faulty it will need replacing, if they are all equal the compressor is faulty.
please do NOT try this i could damage your unit if you don't know what you are doing call a service provider.

Had the same problem c6 my technician fixed the problem this morning. He said the control pannel needed to be changed on the inverter and there was a burnt out wire leading to the control pannel. If you have warranty and your proof of purchase it should be free of charge. Bing Lee refered me to( All general whitegoods and electrical) at Wetheril park, sydney. This company deal with LG products only. I would never buy a split system with an inverter ever again too many problems. Lucky for me I have 5 years extended warranty.The technician gave me a tip and said to clean the filter every 2 weeks if you use the unit constantly. Hope info was helpful.

The remote control air-conditioning has diagnostic tools that diagnose the unit for five minutes. If the diagnostic tools cannot find problem to your unit then it will continue running as normal. But if the diagnostic tools find problem in your unit then it will automatically shutdown for the safety of your unit, to avoid fatal damage.
So I suggest that you have to call a qualified technician.

Hi everybody C6 error code on your lg indoor unit is relating to the outdoor . you need to replace the door coil sensor & pipe discharge sensor ( th 14 thermistor ) not expensive pcb boards .
Hope this helps Curly kev.

We purchased 2 of these units and the error code has appeared on both of them. 1 was fixed some time ago by a tech who replaced a fault part in 2 minutes it has worked perfectly since. The other unit has just thrown the code and is being looked at tomorrow morning so i will list what was replaced... seems to be a LG Artcool issue that should have been recalled i think.

Quick note to PhilHeth. Never Never allow anyone to let refrigerant gas charge vent to atmosphere. This gas is an Ozone depleting gas & it is illegal to relaease. All modern A/C units have a gas charge weighed in at manufacture & this will be sufficent for a set pipe run, Over that length additional charge must be added at the specified rate. Any one that adds or removes gas charge without checking the existing weight of charge (this means reclaiming all refrigerants in to a sealed container) does not know what he is doing & should be reported to the Australian refrigeration Council immediatly.

Hi - I reported this error back in June. Our local LG service mob came out fairly quick &.......'let out some gas'!! I was obviously a bit dubious about this doing much (not that I am any AirCon expert!) but.......it's now late AUG & we've had the unit on almost every evening to heat up the unusually pretty cold Brisbane winter nights & .......the error has not returned!!! He said sometimes, these errors can be caused by a excess build-up of gas pressure. I guess the proof is in the puddin!!! I think half the problem here is that the error is too generic & must cover alot of different possible faults/issues. Hence the confusion & frustration. Anyway - all is forgiven & LG aint so bad afterall.

I have a ductless LG split system. One unit runs fine. The second powers up, vents open, but the fan does not run. Any ideas on this?
