Re: LG Multisplit ongoing issue... slowly getting there I think!
THis is something I checked as well... I have the unit connected to a energy meter and the current draw is the same (I measure in watts or volts) and it draws the same so the compressor is doing as it should. It just doesnt make anysense. Bang it upto 30C and you perhaps might get air off a few degrees warmer.
For example now justturned the unit on for today (been out all night) and getting air off of 43C and its 0.8C outside. Next on cycle may only get 32C air off but changing it to 30C witha return air off 21C it wouldnt increase that much.

Re: LG Multisplit ongoing issue... slowly getting there I think!
Right guys bit of an update and I guess what appears to be a resolution.
No thanks to the engineers involved or lg's £500 a day service techs.
Today was getting air offs worse than when we had the -12c at night so I thought enough is enough I am going to take the covers off outside and look at the valves.
Spend an hour getting to the valves. End up on my hands and knees outside at -2c and notice that all the valve heads but one are not clipped onto the pipe.
They are loose and so the heads have never been seated properly so therefore appear to not have been driving the pin/screw inside. Eg when valve told to fully open it's only been able to open say halfway.
So I pushed all the heads down properly so they were clipped in place and then came back inside and checked air offs and getting nearlly 40c on the problem units.... Which is miles better than 25c I was getting this morning.
Cant believe that after I all I have spent it was something so simple and obvious. Why had my engineer never checked this. Same as LG!
It was getting to the stage where I was going to spend money on getting the valves replaced. I don't think they have ever been clipped on since one of the units was changed over as u really have to struggle at the floor level to see where they clip on.
Just testing it all now but so far so good.

I think that you should stop spending your hard earned cash on various 'engineers' and LG.
Save it up and go on an AC Service Course, you know it makes sense.

Update...
Havent been able to get on in a while but securing the EEV's back in place made no difference at all apart from the bedroom units coil now gets upto temperature quicker and will switch into desired fan speed after about 10minutes of operation!
Have emailed lg and no response as of yet! Useless!

Re: LG Multisplit ongoing issue... slowly getting there I think!
Multisplit units would be a no no at all, I would still reccomend the 1on1 splits as during the cold spell the system worked fine and plenty of heating its just this control strategy that seems to be odd.
Bushyt - lets face it anything is better than that calorex rubbish he has installed.
