So now one year into the AC and having issues. Seems like the 4-in-1 converter is not working. I use it to reduce the tonnage and save power when the temps have been reached and avoid the chills. Inverter models have two provisions to reduce power. One is when the AC is reaching its desired temp, it will start
reducing power gradually. The other is when you reduce the tonnage to either 80,60,40%, it will have a
drastic drop in power. The later one is not working it seems. My Ac would reduce power when it is reaching the temps, but sometimes, it will also increase the power, which I don't understand.
Just now while writing this post, the power dropped from 850 to 400 to 320 units as it was reaching the desired temp Then suddenly it spiked to 440-480 watts and was stable for around 10 mins or so before again dropping to 335W gradually and is sought of stable or declining further.
Any idea what could be the reason? When I use the Himalayan cool mode, it goes full power and cools the room. But when I try to reduce tonnage, it won't drop the consumption.
Has the sensor gone bad? Or the PCB? I doubt on the latter as if this would be the case, then the power consumption wouldn't have declined from its initial start value of 840W and continue running at the same wattage until it gets a trigger to shut down, behaving as a non-inverter ac.
I did give my ODU a nice bath with garden hose, while ensuring the pressure is not great to damage the sensitive fins. After that, I treated the ODU it with a conformal silicon coating to ensure water won't be in contact with the metal during rains or anytime. I didn't spray the PCB coz I am assuming it would have some sought of coating.
Explaining this to the LG technician would be difficult. The last thing I want is for them saying they want to take my ODU, or worst, my entire AC set, for further testing at their place.
Any leads into this matter...
@adder or anyone.
