Lg airconditioner comes up c5 and stops - LG Heating & Cooling

Comms Error: check your wiring, remove external pumps. Split/Multi - check volts from terminal N to 3 = 0 - 65 Vdc, Multi V - 4 Vdc terminals 3 and 4.

Yes replace reset cord. also see an electrician about a surge suppressor for your home this one item will save you alot of money and appliances

If after reset the A/C cools then the fault seems related to the thermostat or the cut off pressure switch or load cut off.
However is there is no cooling at all the compressor and the gas pressure- check for leak if gas is absent.- must be checked .
If compressor is suspect you must check the estimate and decide whether it seems better to scrap and buy a new one.

Drain motor get locked. call repairman to disassemble your indoor for drain pan cleaning and reset. Unit will work o.k.. Helpful?
