Just setting the setpoints lower isn't the best way to put the system into a full load operation. What you need to do is to turn on Dip switch #5 at the ODU, go to "Fdd" mode using the arrow/confirm buttons, and go to "Fd8" for full cooling(or Fd9 for full heating), and then push the confirm button. After a few minutes after it initializes, it should display 6000(countdown from 60 minutes). Also, LG has specific functions in the ODU to measure the charge to let you know how much to add/remove.

[@D2DNYAC]

Sounds like you have some experience with these systems good info

[@D2DNYAC]

Thanks for sharing

[@vadims284]

Does LGMV app show the charge and how much to add/remove?

[@coachjaypoole]

Can I get your number and 10 mins of Knowledge? Lol

[@Rob0243]

That hissing noise you noticed quieting down was not the eev’s they are located on the indoor units individually. That was was the hot gas bypass shutting be cause you had put enough gas in that they weren’t need to prop up the suction pressure any longer.

[@D2DNYAC]

This is awesome 👏 thank you

[@RobertDelp-o1p]

Great info on the LG!

[@D2DNYAC]

Thank you for stopping by

[@HVAC559]

It is my understanding that discharge superheat (discharge pressure temperature - discharge temperature) should also give you a good indication of charge. Below 60F flooding back, above 90F low charge or bad windings. I believe the the system sets compressor speed from this reading.

I thumb up this video because there isn't much info on LGMV. What I would like to see is thorough review of the features and and explanation of troubleshooting steps using this app.

That's challenging
Diagnose the leak

[@D2DNYAC]

I know however I have successfully done it a few times

[@AlexMotivations_]

Im having the same issues on on a multi v system. What gets me is the range and trace pressures match but not the superheat. All of them are high which gives my low on charge suspicion.

[@D2DNYAC]

And you are probably right, especially if the compressors are all not on or running @ low frequencies to maintain that target

[@l.crossjr]

Great content. Where do you commonly find the most leaks on these units?

I’m using the same module but can’t get it set up any way you could give feedback? Can’t find anyone to call. When I hook it up it says I’m missing a key, but I don’t see a driver key and it didn’t come with the usb version I see online.

lol, I got a 2 pipe system in my house using the same mounting tool, Can you leave the tool plugged in all the time or should you remove it when not in use?

[@D2DNYAC]

Up to you

[@desieranks]

Was it locking out on any error. I had a lg multi v low on gas giving an ch 36 error high discharge temp

[@D2DNYAC]

Yes this is good information, because definitely this error will most likely pop up in these circumstances with these types of systems

[@PhamChienHuu]

I also use iPhone, can you give me the link to download this LG MV application?

[@D2DNYAC]

I don't have the link I have the file

[@D2DNYAC]

I could potentially share it over what's app

[@jasamba]

When low and high pressure okay but some indoors not cooling what could be the problem

[@D2DNYAC]

With no error it's most likely under charged

[@jasamba]

@D2DNYAC plz ideas how to check the indoors
