Question about Air Conditioners

1 Answer

I have an lg artcool unit with model numger LSV244VM-4 on the outdoor unit.The ambient temperture is around 15 degrees celcius today so i set the controls for 30 degrees cecius to ask the unit to heat.The indoor unit responds by sending power to the outdoor unit but neither gthe compressor or the condensor fan turn on.The customer told me that "C6" keeps apearing on the remote although this did not occur while i was attending.There is something in the control circuit of the outdoor unit that is preventing it from running it would be of great help if you could shed some light on the matter.

Make sure the indoor filters are clean. The outside unit will continue to run until the indoor reaches the temperature you have selected. Dirty filters can throw the temperature out. Its common for outdoor units to freeze up when on heating mode if the ambient air temperature is below 5 degrees Celcius.. The machine should however, defrost itself. There could be a problem with one of the pipe or air sensors on the outdoor unit.

Charging an air conditioning system


R22 systems should run a 68# to 70# suction pressue. If you look at the suction guage at 68# that is a 40 deg evaporator coil temp.

How 2 add r22


The best way is weigh in a charge. of course the type of unit will come into play as split systems have enough refrigerant factory for up to 15 ft lineset or so, depending on units make etc. If a charge exists already and requires adjusting due to lineset length, or repairs etc, youcan simulate a 95 degree day ambient outdoors by restricting the air flow a bit to artificaially raise the head pressure as do low ambient controls, thus bringing the head to around 270lbs in a r 22 system or ambient plus 30 degrees , converted to prressure, so a 95 deg day plus 30=125 deg converted to pressure is 269 lbs, the indoor air temp being clse to 80 degreees helps, the indoor coil will be 40 degrees cooler than the indoor ambient if all is normal and design conditions are met by God or you. If the indoors 75, go to a 35 d
eg coil temp this is ball park, as the subcooling (15 deg)and superheat (10 at the evap coil, 20 at compressor) will need to be monitered along with amp draw and Delta T or temp differntials suply vs return.2_25_2012_2_55_05_am.png

LG Artcool about 4 yrs old error code CH 05. no heating or cooling. cheers.


CH 5 on these machines indicates a communications error between the indoor and outdoor units. Generally, it will require a replacement outdoor board assy to repair it. Lookup LG parts on the internet or ring them for your nearest Agent or parts stockist.

It sounds like you are low on charge. I think you have a thermostatic expansion valve and you need to check the subcooling, you should have 12 to 15 degrees at 95. At 95 degrees your head should be about 280# for a 12 or 13 SEER unit or higher depending on the effeciency. At 78 to 80 degrees indoor depending on the humidity, that is normal. The valve will open to try to fully feed your indoor coil and it sounds like your head pressure is to low to force enough refrigerant thru the coil.

first of all check the outdoor unit if it is in your reach  than simply touch both the valve & feel the temp if smaller valve is colder than the bigger one than surely the problem is with refrigerant quantity.

Ac won't go down past 78 F while operating the presures are 15/ 150 psi. I think it needs charge. But how much charge what pressure does the low side need to be at?


The temperature outside and pressure chart are needed to accurately determine the proper charge. (temperature pressure charts to calculate heat gain) However the low side of the unit should read around 70 and the high around 210. This is a really broad generalization and I do not recommend you charge your unit just on this info. It will get you close if you are using R-22 and the unit is properly cleaned. A dirty evaporator coil will cause a severe low pressure reading on the low pressure side.

I assume r-22 refrigerant by the pressure... you have a saturate temperature of approximately 41 degree and 71 degrees at the service port this equates to a 30 degree superheat. a condenser saturation temperature of 105 degrees and since the liquid line temp at the service valve is not given only the enterin indoor coil on the liquid line a 96 degree temperature this would equate to a subcooling temperatureof about nine degrees. You have too high of a superheat reading. verify that the bulb for the txv is correctly positioned and insulated. if it is then you need to remove the bulb from the suction line, hold it in your hand to warm it up and see if the superheat changes. you could also have issues with your ductwork. If the supply temperture is around 50-55 degrees then the unit is doing all it can.. Check the txv and the ductwork as the subcooling indicates that the condenser side is doing it's job, but the superheat readings indicate that you are starving the evaporator..
