Hi I have a lg inverter V (Air coditioner) when I turn it on , only the power lamp flashes 5 time & after 2 second falshes 5 times & it is continuing but the inverter doesnt turn on.


Its a communications error. You will need a new outdoor board. Check with LG for nearest parts Centre or Authorised Agent. You have what is known as a CH5 error. You will need the model of the outdoor unit to get the correct part.

My air conditionner is not working properly. It sends cool aire keep getting code E3 What can I do to fix it Tks


micheline, according to the LG Owner's Manual for the Model Number you listed, there is no LED display on the casement window unit (please see the Owner's Manual link below). How are you getting an E3 error code? Or by chance, did you list the wrong model number? Even Goldstar, that is made by LG, doesn't show your model number.

Please advise. Thanks.

ERROR CODE CH5 AIRCON SPLIT LG


This error is a communication error between your indoor and outdoor unit. You can try turning the breaker off for a few minutes and restart the unit. However if that does not work its best suggested to have an authorized HVAC technician service the unit.
