I bought this model: MFL69782201 (User manual PDF http://gscs-b2c.lge.com/downloadFile?fileId=S45tMoOwlLqIpW2lkIGLfA) It is a split dual inverter.

The problem is there is no way to disable it's beep that happens every time we press a button in the remote control. I contacted the manufacturer and they say "it is how it works and is impossible to disable the beep".

The noise is very annoying, mostly in the morning, and mostly because I live in an apartment. I dont want that noise to cause trouble with my neighbours.

I know if I make a hole on it somewhere I will be able to reach the beeper and cut it out or block it enough to lower the beep volume in a hardware way.

But I can't find a maintenance manual for it, so I dont know where to cut. Yes I am aware about warranty, but... The beep is so horrible that I avoid using it as much I can. I feel like I bought the wrong product...

So, has anyone done that kind of thing?
Did it work?
Where can I find such maintenance manual?
Cut or damage the utterly annoying beeper can cause other problems on the circuit board?

    why would you cut a hole in the AC cabinet? ... how did that thought even enter your head? ... just take off the cover, find the beeper and cover it with tape

  • You could just set it and leave it set, too. No need to press a button = no beeps.

  • @Ecnerwal when I turn it on, it "sings" loudly for about 3s... If I need to change the temperature it makes a loud beep for every button press, I mean, I cant just set and leave it, I need to have access to these controls at anytime. Jul 5 '20 at 2:05
  • @jsotola mmm... I lift a movable panel but I couldnt see the control board. To take off the whole cover I would have to have access to the backside of it where are the screws, but it is on the wall. It is already installed (of course) and I am scared of messing with the gas tubes that connect to it. But I will look more to see if there is something safe that I could do, what a mess, I should have bought from some other manufacturer... Jul 5 '20 at 2:10

    Your indoor unit will have two or more screws (often near the blower) that hold the cover. The cover in most split units can be removed easily without messing with the gas pipes or dismounting the whole unit from the wall. Watch some videos on how split ac units are serviced. Take off the cover and maybe you can find the exact part that makes the beep and do something about it. If you are not able to remove the cover then call the service guys (they clean the coils) and when they arrive ask them to do something about the beep.
