You will need a pair of guages and some nitrogen. put pressure to the lines and listen for the "hiss".rubbing soapy water on the area where you think the leak is at will make bubbles (the leak). another way is dye but i do not reccomend it. once you find the leak you run into the problem of soldering the leak and recharging the system, which requires an epa license for the purchase of refrigerant. yout best best is to call the pro's. this is tedious work.

LS-1260HL split A/C. Why isn't it blowing at full speed in cool mode?


ice on indoor units can be from blocked evaporator fins / blocked filters
inspect the fins under the filter pads and if they look greasy and dirty have the indoor unit professionally cleaned as it is messy

Cannot find a filter location for RCBA 4882GG21.


it is either in the bottom of the indoor unit itself, in the door below the inside unit (if equipped), or in the grill on the wall or ceiling

I had bought a Lg inverter wall mounted unit it worked about 3 days but it didnt cooled the area and i decieded to changed the outdoor unit(compressor)according to repairman's advice .during the first...


You changed the compressor?? Why ??? These models do not normally have problems with this. I am conversant with most of the LS series and these have capacitor start compressors, which fail all the time. Generally all models have either a 45 /6 uf or a 50 /6 uf capacitor. If this fails, the compressor wont start, thus a no heat, no cool problem. If you have changed the compressor and made sure it is actually running, what is the operating pressure?? Suction side should be around 0 to -5 degrees c. Perhaps there isnt any gas in the system??
I assume by doing such a repair you are licensed to do so and have all the proper equipment to recharge the system ???

When do i refil gas is it when is on or off


why do you think you need to refill the gas ? what kind of gas are you putting in it do you know how to tell how much you put in. the gas never runs out if it is not cooling as good and you think putting more gas in it will fix it think again. it might have a gas leak and if it does its highly illegal to add more gas to it.. you add gas when its turned onto cooling on the big pipe side but please rethink what your doing and answer some of my questions first.
