C6 error on airconditioner

I have been called to a site with an LG high wall airconditioner model: s12ahn (outdoor)

It has a C6 error.

I reset the power at the power point and all looks good now.
What does this error mean and should i be looking further?

6 - DC Peak Error

• Supplied power is not normal

• Comp Connector (CN-U,V,W) is disconnected or inserted to wrong

position

• Compressor is damaged (coil short) ? replace compressor

• Too much Refrigerant
• Defect in outdoor pcb assembly ? replace pcb assembly


Try turning power off to external unit, usually resets diagnostics and runs OK. If not PCB external unit likely culprit, replace!

ERROR CODE ON AIRCONDITIONER LG ART COOL INVERTER MODEL NUMBER LSZ244VM4


Hi,

The first thing i'll say is you will need to get it repaired by a technician and i strongly recommend you not to do it by urself.

Remote control units have diagnostic program in the
control, after 3 to 5 minutes of operating if the diagnostic
tools detect abnormal operation, then its shutdown the unit
to protect from damage. Thermistor sensor is one of the
parts that detect the operation of the unit. Out of range
or defective thermistor can shut the operation of the unit.
-
If your indoor and outdoor is clean start the unit in cool mode and monitor the outdoor pipes. If your suction pipe is icing or dry then your unit is under charge, but if your suction is cold and sweating then the system is ok and sure that the thermistor sensor is defective.
- Out of range thermistor sensor in both return air and freeze up sensor can cause the tripping “off “ the unit.

Our airconditioner has the code C6 on it. It has cut out and displayed that code. We were instructed to turn it off at the power board and turn it back on, which we did. It went back on again and tried to...


I previously asked you, if the C6 appear on the unit or on the hand held remote. I contacted a friend of mine who is a service technician for the LG Split System units and he advised that it's an error code that can only be solved by a LG trained service tech or LG itself. It may have been caused by a power surge, which may have caused some damage to the circuit board.

Sorry I couldn't be of more help.

Hello have a inverter LG Airconditioner and it keeps turning itself off and showing the letters C6? Any ideas


Error Code: C6 Problem: Inverter compressor run current high

SOLUTIONS:
- check [resistance of] compressor windings all equal 1 to 4 ohms

- check [resistance] to earth 50 Mohm minimum

- check run current

I'd also check the motor capacitor(s)

Probably best to explain/print out and give to authorised serviceman

C6 error on neo plasma LG


There are two reasons for this one is that there is a "DC PEAK ERROR" meaning that there is a communication failure between indoor and outdoor pc board and not a condenser failure. The second could be that the indoor outlet sensor is faulty or is being missed by the intergrated circuit board. Either way I would look at the indoor pc board replacement. Hope this helps
