Lg Air con

[Chris2005]

Hi Everyone,

Is anyone out there having problems with lg..
A few months ago we fitted 2 7kw r410 cassete units.
After a month one of the units shown fault code ch45 so we got on to the supplier and got new probes for the outside unit which solved that problem.
Now both units are showing fault code ch33 high discharge temp..The units were on heat mode at the time.
We reset the units and there running o.k now until the next time..I cant find any reason for this happening the checked the filters and there clean.

We have also had to replace boards on the floor ceiling convertables under gaurantee ...

And the last time we ordered units we were told it might take a month to get them as lg had recalled all that model cos of problems with the boards..

I think its time to start using mitsi..
Chris..

Is anyone out there having problems with lg..

No, never, LG is the best air con unit out there.

Is the gas charge ok? not to much?
Air in system?
Fans running ok?

[Brian_UK]

I thought the first reply to Chris would have been - "Oh no! not another LG question?!?!"

[Chris2005]

Hi chillen..

The system was well vact out and the extra gas was put in using the electronic scales,
And the fans are running fine,
The units have been running for a few months fine apart from the probe prob on one unit.

I just thought it strange how both independant units brought up the same fault code at the same time ..

Chris..

[Abe]

Same batch

Remember, according to LG, they churn out one every few seconds.....

Which in my book says, No Quality Control Checks

[rbartlett]

just to bring everyone up to speed LG have released a tech bulletin regarding the CH3 fault on the small splits

If you have one giving trouble contact your dealer for the upgrade

cheers

Chilling was being sarcastic............
He doesnt "really" love LG

[jteixiera]

mate check ure indoor unit fan operation and check ure filters discharge temp usually short of gas to much superheat check ure subcooling

[Andy W]

I have been out to another LG today with the compresor down, I could compile a list of faults that myself and a coleague have come across that LG the bunch of ***** deny. I have got to fit 2 compressors, 2 fan speed controllers and 2 defrost boards to a total of 3 machines, wish I had never set eyes on LG.

[puddleboy3]

Question are both units in the same room?, if so where they commissioned at the same time? High discharge temp 9/10 relate to shortage of refrigerant. Are you sure that the pipes are not crossed, very common!

[Andy W]

Don't forget, LG are still having electronic problems that have not yet been solved that they will deny as they dont want a repeat of the withdrawl of the new range from sale as happened a few months back when all the machines were put in quarantine and loads of electronics were replaced. They won't tell you that but I had the information from an wholesaler who was told by LG themselves. Korean electronics = unreliable.

[Ireland]

I've been using them as a "cheap" option for the last couple of years.

We always oversize the units as this seems to be the only way to stay out of trouble.

And it is best to go to the troube of installing the hard-wired remote controls (if supplied) as they do get rid of some of the nuisance problems (don't know why, it just did for us).

Plus the hard-wired ones help with trouble-shooting.

[Andy W]

I've been using them as a "cheap" option for the last couple of years.

2 years is about right before the problems start. I presume that you are all aware that the fan speed controllers are not up to the job and the first thing to happen is the fans work intermittently, then the board blows usually in the same place, then the fans stop, the compressor overheats and starts to blow off on the internal pressure releif valve, this happens in between of maintenance visits so you dont catch it, it then cooks the compressor. Now try getting a compressor from LG, ok, you now have the compressor, try getting the fitting allowance, I can't. I am owed for fitting a complete set of plastics, modifications to a 10.6 cassette that LG could not sort out, fitting a compressor, 3 fan speed control boards, 2 defrost boards and a contactor.

A friend of mine specialised in just LG and had so many problems and had to fit so many parts it was unbelievable, LG = loads of garbage.

[NoNickName]

I just had a return scroll from LG. The wires from the connection box disconnected from the inside of the compressor.
This is really a **** brand.

[dougie]

lg must be one of the worst makes out there,very cheap and nasty.

[Andy W]

Another problem as reared its head on one of my sites, CH03 fault code, communication error between cassette PCB and wall mounted hard wired remote controller, happened 3 times now, wiring plugs tight, no light tubes popped etc causing spikes, changed the remote controllers over as there are 2 systems on site, waiting for fault to reappear so I can make a decision on what is faulty.

[Alex Harvey]

In Spain there is a saying 'cheap is dear'. One call back costs more than the price difference between these cheap brands and a Daikin. The lesson is clear. As an industry, we should steer clear of the cheap brands and tell our customers when quoting that going for the high quality brands will only make a small difference to the overall price (something about 10%). Most customers understand this. If price is all that matters to them, best leave them to someone else.

[PJB]

The only issue with LG is that there are som untrained monkeys installing it because of its price. Fact!
(obvioulsy no one that has the brains to visit a site like this)

Installed correctly, from my experience, its as reliable as anything.

True LG have some problems but ive yet to find a brand which doesnt. Its 100x better than 4 years ago.

This in incorrect

Many members who have had problems are experienced engineers on this forum

I personally have experienced problems and I for one will not be installing any LG in future.

LG need to convince me that the quality issues appertaining to reliability have been addressed

Are you by any chance employed directly or indirectly by LG or do you work for a distributor of LG. My 28 years experience in the refrigeration & air conditioning industry means that by now I think I have got the hang of this installing split type air conditioners, the first air con I ever installed was an old wooden cased Qualitair back in 1980. You better believe it, LG make rubbish equipment, the distributors are rubbish,( I have now dealt with 2 independant dealers and 3 distributors, the after sales and technical back up is non existant, the warranty procedure is a joke. Recently I have fitted a complete set of plastics, a compressor, 3 fan speed controllers, 2 deforst boards and 1 remote controller, I have not received a penny for my labour. I have also had a problem that LG could not solve and washed there hands of, it was left to me to come up with a solution at my own cost before my customer would pay me, now are you telling me that LG are any good as a product or a company?

[rbartlett]

M*rc and I have been discussing this very issue and we have come to the conclusion that quite a high percentage of LG's problems is that they have reversed the progress of 'splits' whilst hanging on the 'me too' band wagon.

IE a Daikin is quite a simplistic installation which needs little or no brain power to install or even actual commission.

However LG have pretended to be in a similar vein and indeed tried to make us believe they simplified it even further by pushing it down further the path of 'white goods'

However (and this is the rub) their equipment was actually many many years behind the 'state of the art' and actually requires a higher technical level of refrigeration knowledge when the installation falls outside their tight restraints.

IE a 407c kw ducted has a liquid line not a 'pre expansion' line. Not many 'bashers' have ever seen a liquid line let alone actually installed or commissioned one.Believe me the average 'basher' is easily confused which is why they like Daikin etc so much

They don't usually provide a gms/m for additional charge and again this will mean the 'basher' will bodge/guess With the bottle inverted and "one Mississippi two Mississippi" charging as they have no real idea how to check superheat.

The seasoned installer is also able to fall into the trap of thinking like a 'basher' as having installed Daikin Tosh, Mitzi ET AL it was a case of 'there you go luv' once the power is on.

I myself have been caught by the LG/Daikin where the power wasn't supplied before a Daikin install and I have actually told the customer " don't worry just tell the sparks to turn it on -It'll work as they ALWAYS do"

However LG are a different matter and we have had loads of silly issues where the incorrect charge level caused intermittent and strange faults. I now know we have to allow an extra 3-4 hours commissioning to certain LG installs and then (and only then) will reliability meet expectations...

The quality is an issue as they targeted the 'basher' and his market so they do carry the blame for this.

However it is a fact that they came into the market with an almost wilful aim to mislead the market and the installers and bear rightly the result...

Try Hawco and Gordon -he knows their product very well.

I spoke to LG technical in Slough about the fact that the non inverter in ceiling ducted turn off the fan in heat mode once satisfied and the guy there seemed to know his stuff (he agreed this was not a good idea but got knocked back previously when asking for a 'fix' by LG Korea) Although I was the first ever official complaint on this btw...

LOL.

Meowww. carefull, Frank may be listening.


It seems once again that Fujitsu is clearly far better than anything else. it's cheapish, and you can install and walk away leaving the end user to power up and chill out.

[Karl Hofmann]

(obvioulsy no one that has the brains to visit a site like this)

True, there are some untrained monkey out there chucking them in, this is because LG are happy to sell their goods to untrained monkeys, making life difficult for us highly trained monkeys

Installed correctly, from my experience, its as reliable as anything.

Some of their stuff works very well, some of their stuff is crap but I am not going to ruin my reputation and my bank account finding out which is which

True LG have some problems but ive yet to find a brand which doesnt. Its 100x better than 4 years ago.

And in another four years it will be 100 times better than today. Why can't we cut the crap and have good stuff today? Even the public are wise to LG

[frank]

Oh - and don't forget to leave him the earplugs as excessive exposure to Fujitsu can leave the hearing damaged

We have had nothing but trouble with LG and from the Service we recieved From LG.

Im not going to go into detail on a public forum, but even LGs own Engineer could not fix the fault with a LG Cassette.
When they said " weel replace it if it drips water again"
Guess what, they denied that they ever said that, the unit continued to leak and i had to foot the bill take the heap of junk out and install a Mitsi Heavy unit. Job done.

As for Fujitsu Cassettes ! Anyone have bits of plastic falling off them ?
The old Fujitsu cassettes were great
As soon as the new ones came out, bits were falling off quicker than they could be fitted back on :lol:

We have been Installing Mitsi Heavy for 3 years now and are enjoying NO call backs to any of the range.
Profits are up due to this and everything is Rosey :lol:

[racs]

As no equipment is now made in this country surely some damage is done in shipping?
I have been involved in selling all of the makes mentioned previously with the exception of LG. As far as i can ascertain most problems occur either from a quality issue or which is most often the case prices being driven down to such a level that quality goes out of the window.

[matt black]

Hi, the fault is with the outdoor board. This is a known fault. Contact Hawco for solution. I have had this on 26 units, all are now fine.

Matt Black

[Andy W]

Had another fan speed control module fail this afternoon on a 14KW HP cassette, this appears to be the most common part to fail and LG are still issuing the same unmodified part even though they are aware of the failure rates.

[Steve Metcalfe]

Hi I am new to the forum but not new to the problems with LG.
We have had to many problems to mention with LG.
The latest being a pipe cracking next to the reverser valve on the outdoor. We have decided to braise this due to the problem of getting a replacement from LG.
Lg's answer to every problem is poor installation!!!

We are a Daikin approved installer and all of my guys are highly qualified engineers and LG have the cheek to send there own (totally unbiased engineer) out as we had had so many problems. Despite having each unit inspected by other companies to verify our install LG still refuse to honour the warranty. We dont supply LG anymore needless to say but I have had to change 10k's worth of kit to keep my customers happy(obviously a concept that LG do not Understand) my advice only fit quality stuff like Fujitsu, Mitsi or preferably Daikin of which we have fitte £100k's worth since March and had no issues at all or any of the 200 units we fitted last year!!!!!

I can not tell you how angry and dissapointed I am with LG, my workmanship has never been criticised, I was even complimented on how good it was by the LG warranty inspector, I eventually got all my parts on warranty but have never received a penny in labour allowance, last month alone I installed 5 Fujitsu's and ordered another 2 for this month and I do not specialise in installations as the core of my business is service calls, of those systems I would normally of used LG, LG have got to be suffering sales wise by the amount of feedback I have received. When will LG listen to experienced professional engineers and stop blaming every one else for their poor quality, sub standard products.

LUCKY GOLDSTAR absolute **** 4 high wall units 2 years ago split condensers, fans packed up, no HP switches.First kit on R410 never again sorry to say Fujitsu rules.

Dont blame you, We stopped installing LG units a few years back, We laugh at the poor Shop owners who are having LG units unstalled, its like installing a Time Bomb

We have been Installing Mitsi Heavy for over 3 years now and in over 500 Units we have only Had ONE problem !! Last week we needed to order a replacement outside Board We were Gutted, in 500 units we finally had one that didnt work

[S_Line]

II installed 5 Fujitsu's and ordered another 2 for this month and I do not specialise in installations as the core of my business is service calls, of those systems I would normally of used LG, .

Try a Mitsi Heavy Cassette, far better than a Fujitsi Trust me

I pledge thy allegiance to Copland! Custom built Copland plants are the only way to go IMO. I see it like I see a computer the only way to do it right is do it custom.

LG worked hard to gain the the Golden Bollock award three years running, judging by some of the rantings on this site.

Does that mean that you'll be marketing kit that works and have technical support that knows what it's doing?

[Brian_UK]

Welcome Hendrag to the forum.

Full marks to you for being brave enough to annouce your involvement with LG.

Lets hope that your hidden promise comes to fruition.

[Andy W]

Discovered another fan speed board and 2 fan capacitors gone this week while carrying out maintenance, lost count now and my wholesaler still says save your breath, you have got no chance of getting parts under warranty from Shorts.

[Renato RR]

Hendrag,where can we pick up service manuall for LG air con?

So big company and without good manuall.We instold about 100 LG units so far 1 problem with remote and one with fan of idoor unit but we also instold 100 Fuego and 30 Vivax and no problem at all.They are dgust noisi units with stif plastic parts.

So to conclude te 90% of yob is good instalation.I have more hadeike with chillers produced in EU then with split system produced in China.

Best regards,
Renato

How do you sleep at night? are you currently being recruited by Horlicks for their television campaign in the UK?

LG should never have entered the uk market without years of test running on sample sites, Lucky Goldstars name failed in the early 90's with their c**p televisions. But no they decide to relaunch under LG conning nearly all the UK customers out there.

LG products and technical assistance stink.

Hendrag,

Fool me once - shame on you, fool me twice - Shame on me.

The embarrasment and cost to me of ripping out a two and a bit year old LG and replacing it with a similarly priced Sanyo, free of charge to the customer will stay with me for a very long time indeed

[Abe]

The power of Marketing is the real culprit.

Multinationals use Marketing as a tool for market entry. This is when ill equipped products are launched rapidly into the market without " evolving"

Hence the expenditure of dollars catapulted the brand within a short space of time, using clever strategies, cheap prices, incentives, etc

Multinationals develop a branding, farm out production of virtually everything from cameras to washing machines, and paste their logo onto the product.

The brand is supposed to inbibe confidence in the product. But when you think on it, the brand is meaningless, all it is is an image, a perception which is enhanced by money.

The products are churned out by multiple factory units, who perfect the art of producing for anyone who buys in sufficient numbers to qualify for a brand name to be stuck on it.

Eastern companies have perfected the art of multi nation al operations......

Some do it better than others. In the end the consumers have spoken....
