Hi all. I know - it's an LG! A12AWD, AS-W12PDGO, SP1 chassis. One of those 'Art Cool' interior units.
Called to unit which according to client is 'short of gas'. Absolute crap install, but the end result is error code C6. Excessive current at inverter.
Compressor does not run at all, but fan motor does. Fan motor runs for less than 1 minute and shuts down. This is repeated 4 times, and interior unit displays C6 and total unit shutdown. Disconnect compressor and the sequence is the same.
Resistances at compressor windings within the LG range of between 1 and 5 ohms each.
Yellow - Blue 2.5ohms,
Yellow - Red 2.7ohms,
Blue - Red 2.9ohms
I wouldn't have thought that the difference in resistances significant.

I've removed the PCB and have just kicked under my desk until I've some clue as to where the fault lies!

Any ideas??
