    I have LG BS-Q1865NA0 Inverter V Gen Cool Split Type AC. Recently it stopped working. The green power ON green L.E.D blinks 5 times while the Generactor Mode (Gen Mode) orange L.E.D blinks 6 times interchangeably on the indoor unit. The green blinks 5 times…goes off…then the orange blinks 6 times…goes off. Then the cycle continues. What could be the problem?

    What might be the possible cause of the out door condensercoil overheating.

    • willy says:

      it could be a restricted condenser coil, dirty, blower fan rotation weaken or it run on the wrong way. It could be also due to excessive load in the room where the indoor installed. Sealed the room and avoid excessive door opening.

    • Godgift Edomwonyi says:

      The out door condenser may be due for servicing. try servicing it.

    We have a LG mini split wall mounted combo air conditioner/heater. We had the heater on and it stopped heating. The amber star light is blinking twice and then the green power light flashes once. The blinking lights keep cycling. Model #LS360HV3. We have checked the manual and nothing regarding this issue. Filter, batteries, thermostat all seem to be good.

  30. jahesh says:

    im really disappointed with LG. first i bought LG G3 mobile. it lasted only 1 year.

    now recently i bought the highest expensive model of microwave. after 3 months it started showing F11 error. since under warranty i got it back repaired cause was PCB defective. what nonsense…

    now on the same day after a long winter season we put the LG inverter AC i22tqc model on. after a shile it started showing code CH 38 or CH38.

    no where mentioning about this error. only one person told in the forum to clean filter. but after cleaning its the same error.

    LG brand is really really bad.
