AC cooling below than set temperature

47°

Have LG 1 ton AC in a small room (around 10x10) and at night, if the temperature set is around 25° in the remote with room temperature at 30°, then after few hours, it was 22° instead of being around the temperature set which is 25°.

Any idea if this requires servicing or usual thing?

Looks like you are using AI (artificial intelligence) mode for cooling.

Press the mode button to toggle between the modes. 

Change to manual mode and set the desired temperature. 

Also if you use sleep mode, then AC will gradually increase the temperature at night.

This is in manual mode only, where I have explicitly set the temperature to 25°. AI mode doesn't seem to have option to configure the fan speed etc, so not using AI mode

Smacking the remote a couple of times will make it work... if not, hit the AC itself with the remote a few times and you will be good to go XD

22°C is shown as set on the AC or it shows as room temperature on the remote?

22° is shown as room temperature on the remote. AC display says at 25°

Some models have temp sensors on the indoor unit. 22° might be the temp near the AC unit which will obviously be lower than rest of the room.

If your remote has a temp sensor, try moving it and see if the temp fluctuates.

Remote has the sensor i think, but remote was far from AC when it showed 22° but in AC display, it should be around 25°

Could be a faulty or improperly calibrated sensor. 


Don't think too much about the displayed temp. If it's a non-inverter AC, your AC might shut itself down to bring the temp back to 25°.


Just set your desired temp and sleep peacefully. I would worry if the difference in temp was huge or inconsistent.
