Re: Split System Air conditioner

There normally two types of leakages from the wall unit.
1.The warm air in the room when comes in contact with the cooling coil of heat exchanger (consisting of fine fins where compressed refrigerant evaporates) looses its heat & cannot retain the same moisture content at lower temperature at the point of contact with evaporator. There is a provision of a drain pipe to carry this condensed water to outside water drain. So if the drain pipe is choked or the coupling joint of the drain pipe at the bottom of cooling coil is not proper, there will be water leakage, This can be easily attended by physically looking at the fittings.
2.The second problem can be the leakage of the refrigerant. If there is second type of problem, then there will be very little or no cooling irrespective of continuous running of air conditioner. This can be easily checked by feeling the temperature of outlet air from the air conditioner.

Conclusion-As you have written that there is leakage from the air conditioner, but you have not written whether it is visible or invisible. If the leakage is visible, it is problem number 1 & if it is invisible, it is problem number 2.

If you are not satisfied you are free to ask for more explanations.

Re: Split System Air conditioner

If it is water leaking check the indoor drain pan if overflow with water.If the pan is overflow with water then you need to clean your drain pan and drain pipe. While the unit is operating check the drain pipe if water drip, if no water coming out from drain pipe you need to flush it with water to flush out the restriction.
Try also to check if no icing build in the evaporator fins. If icing is present then you need to clean your indoor evaporator pins and air filter. But if it is clean and still icing is present then your unit is out of gas.

Need a new remote

I would contact your local LG. Also many electronic places sell universal ac remotes (check the packaging to ensure that it can control LG's). The universals are cheaper and easy to set up (they come with step-by-step setup instructions). Hope this helps I take the time to answer your question so please rate me

Water leaking from indoor unit against the wall.

It's probably the insulation around your refrigerant pipes. If it is too thin or missing in a section they will condensate.

Water leaking out from wall mounted head unit.

A little too vague, but probably the evaporator drain is disconnected, plugged up or was never installed.

MY split ac is leaking water from the wall unit, it has been doin

Usually an AC unit builds up condensation. If you have a drain hoole or hose that is clogged up therefore not allowing the build up to drain off it will spill over the top of whatever housing the condensation goes into. If you can look for that issue first.

Fujitsu wall mounted air conditioner.

 during Cooling and Dry modes, if the unit is used under conditions of
lower temperature (18C)  the heat-exchanger may freeze, leading to water leakage and other damage.
If the unit is used for long periods under high-humidity conditions, condensation may form on the surface of the indoor
unit, and drip onto the floor or other objects underneath. (About 80% or more)

Increase Temp to 20 and also run coil dry cycle,
