Anyone know how to solve this problem?

I am having problem with one of the 1HP air conditioner unit from Panasonic. Problem started after about one month after installation.
It seems that it is noisy when the air swing is allow to swing.
Their technicians have made 5 attempts to rectify the problem and till now, the problem still persist.
It seems that they are using trial & error method. Every time, when they come, just apply some grease onto the moving parts and the next time, come and change the air vent. After using for a few days, after the grease dries up, the noise comes back.
Now, the warranty is about to expire...

Written to their Customer Care dept, then they called and want to try to apply grease and replace the air vent again. Really don't know when all these trial & error will end and problem solve.

Really regretted installing the Pana aircon. Some more went and installed 4 units. Include the older set (2 years ago), so, in total 5 units.

Buying things sometimes depend on luck too..

So far no problem with pana air-con in my current house..

but for my new house, i plan to use york...

My mum's house has using Panasonic air conditioner for so many years. No problem. A few friends also using panasonic air con, also did not hear them commenting. Have installed one unit of Pana 2 years ago. Also no problem.

But when installed the new model Panasonic, then encountered problem.
During one of their trips, one of their technician accidentally mentioned that they have encountered similar problem and have not managed to resolve them. So, if the problem still persist, then just do not allow the air vent to swing. Have to live with it.

So, I would say that the older model are reliable but not so for the newer model.

So all 4 units noisy or just the one?

The noisy problem from the air vent movements on 2 units have been solve (hopefully will be permanent) while the one in the bedroom is still not solve. Damn irritating since it is in the bedroom

i got a question here...it is about my panasonic 1hp inverter air cond installed last month. the problem is the nanoeg function like now not working fine (light turned off).
from complete shutdown, if i on the unit, the blue light of the nanoeg feature will turn on, but a couple of minutes, i will auto turn it off. pressing the button from the controller does not help. the thing is working for the 1st 1 month. any body got any idea? thanks

SWAP

Suggest that you lodge your complain with Panasonic. get the complain ref no. Keep calling them if no response.

Problem is that those are 1.5Hp while the one in the bedroom is 1HP.
Anyway, the noisy problem solved after replacing the indoor unit (CS-PC9MKH) with the newer modal (CS-C9NKH)
it seems that Panasonic's older model has some design fault with its air swing mechanism...

1 and 1.5hp indoor unit can be swap de. last time 1.5hp indoor broke then put 1.0hp indoor unit, working fine.

Maybe the indoor unit can be interchange...
But since they are under warranty, if pandai pandai go and interchange, then if happen to claim for warranty later, then problem. Usual la... when claim for warranty they will find reasons to get out of responsibility...
Since still under warranty, then let Panasonic rectify their product design fault.

My panasonic eco navi also noisy when it swing, somemore the unit under 1 year... expensive but lousy quality.

My study room using mitsubishi mr. slim, 3 years not a single noise from the air cond. My new house will be 100% mitsubishi.

Ya Mitsubishi is good, York is depending on luck, and Panasonic Inverter in my bedroom quite noisy suddenly in the middle of the night! Expensive some more, gas also different than normal gas, need to add RM40-50 for inverter gas. Regret.

If still under warranty, just keep complaining to Panasonic. If you complain hard enough, they will replace it. hehehe
Also don't forget the consumer tribunal if they(Pana) do not act on your complains. There has been a few complains lodge by various purchaser of the product... The consumer tribunal is effective although as bit slow...but the message gets across to the rightful party.

Ya, my stupid econavi also will cause noise middle of the night, sound like raining but actually is the plastic and blower sound.
The thing is, panasonic econavi price is more or less similar to Mitsubishi Mr. Slim... I bought it cause I want to try different brand and everyone told me pana is quite good...

True that they can come and service but i dun think everyone so free to keep waiting for their engineer at home, its not once a year....more than that...

Conclusion, if can go for other brand, lol.

I'm using Pana Econavi and it's okay so far

Depending on which model you are having...
I believe on the latest model, they have changed the swing mechanism and hopefully solve the air swing noisy problem..

Why not ask them to replace the parts of your Panasonic air-con since its not working even there fixing the problem. I guess you can do that since they new about your problem.

panasonic eco navi tat bad meh? Deng lo, just bought all unit for my 2.5 storey home. totally 8 sets

My one is okay for econavi.

If you are getting the latest model, should be OK as they have may have rectify the problem with their previous model's air swing mechanism.

oh, shit i was planning to install panasonic ac for my unit....
can some one recommend other brand than PANA ???

Try Daikin.. Frankly if I had not installed Pana, would have gone for Daikin

Daikin is absolutely pro in aircond, solid built quality and yet quiet operation.

#1 in Japan.

Added on April 24, 2012, 10:21 amMore high tech sensor in the blower, more unexpected problem from the blower. This is a logic situation.

Before buying, the Econ navi selling point is drooling among the customers. But most purchasers never bother the problem brought by the sensor.

i got one quatation for pana inverter 1.5 KUDA RM1600 .....
PENING BIN VENING ALREADY BRO

They are mostly around the same price region.. maybe different of RM30-50
Where are you located? Think you could try PM iamsobloodysick
He is selling Pana, Daikin, York, etc

i also regret choosing Pana air-cond.. i'm not using those econ navi series though..

but the previous ones..



i've been using them for the past 4 yrs...

all were ok, until they get noisy after regular services...


the noisiest ones are located in my bedroom and dining area..

those are the most used ones lah... both also 2.5HP


the others, smaller HP ones, still ok... not noisy YET...



for sure, the next time i want to buy, i'll choose another brand, either Daikin or York...

no more Panasonic ...

Some people also mentioned that York is noisy.....

Daikin then..

Yup, york indoor confirm noisy than other..esp 2hp n above. Now my only 1.5hp wall unit also aking noise when switch to sleep mode:(
One thing good about york is fast response on complaints , sure turn up at your door step the next day.

there were two occasions we found ice-forms in our indoor blower unit...

either we didnt clean it regular enough or it had been switched on for too long hours..

Go for Toshiba, Mitsubishi or Sharp. Sanyo and Pana ...errrr... having bad experience with noise with the outdoor units.

on the panasonic aircon just finish install 4 unit today by the aircon contractor, but funny story is that one compressor had writing on the top "sensor had issue" but still pack in the box, complain to TBM they willing to exchange another unit but the real story start here rather the unit being send back to the manufacture they simply clear up the writing on the top of the compressor and repack and sold again.

1st how come the compressor had issue pack and send to the customer
2nd are the retailer want to get more profit by selling issue compressor

The solution is only change the swing motor,
All the rest to be solve up

Nope. Change the whole blower unit to the never model. Problem solved

Aiks... Just got Panasonic airconds installed for the whole house about a month back.
Using a mix of the normal and EcoNavi models.... fingers crossed that everything works well.

Used Daikin aircond before at my parents place and that was one aircond that was forever giving me problems. From water leaks to air being not cold enough... it was a constant every couple of months nightmare. Had it changed to an older model Pana and used it a couple of years before i moved out of my parents place with no issues.

Aircond still going strong and cold even though i've not slept in that room in over a year. Maybe its a mix of the aircond manufacturers, the sellers and a lil bit of luck that determines a persons experience with a specific brand.

Why not try the Mitsubishi starmex inverter.
Quiet and reliable @ 19db in supper quite mode and 1 fan level at only 21db.
Outdoor also quiet and bigger size design like 1.5hp and above.

the aircond water leakage (too dirty?) and the air is not cold (concealed piping?), it could be related to workmanship or product defect.

I reckon that sometimes, buying products will depends on your luck. If you are unlucky, you happen to get those batch or model that were not properly designed, etc. Then you are in trouble. I would say that the previous Panasonic model sucks. Problem with their swing mechanism. This is confirmed by their own technical people. That's why they came out with the latest model so fast.

Their latest model is better. Not forgetting those earlier one are also OK. This is from my own personal experience. My mum's and some of my friends' and also the one that I installed more than 2 years ago. All Pana brand. They are OK. No complain at all.

Since you have installed them, just monitor. If there are any problem, quickly lodge your complain during the warranty period. What I did was to extend the warranty of the aircon since I do not have confidence in that particular model..just for the peace of mind...

Don't worry lah. I have been using panasonic aircon for over 14yrs. Change to 2nd set due to old age. Panasonic also.

Just becarefull with the installation and the servicing. This are the main cause that your aircon getting worst.

anyone can intro a good and reliable aircond service guy. Need to service my panasonic already 1 years old. not cold now.

If your new aircon is not cold after only one year, then these must be some thing wrong with it... Maybe you should claim for warranty. Or maybe there is gas leakage somewhere...

What model is ur air conditioner?...heavy usage?

Usually an air conditioner need to be serviced after how many years?...

For me, normally, I just clean the vent inside the blower unit. Just open the cover and clean the filter. The frequency will be dependent on the environment. If dirty and use frequently, then need to clean more frequent.

If suddenly got ice flying out.. small Pierce ice flying when I sleep in midnight just now..Panasonic 1.0 inverter. Seem alot problem...I buying time after 1 month then problem come...aircond with fresh hot air coming out.. then they come fix and after few month now got ice come out..

Your ac need service already, have u ever clean the filter? Can make ice mean your ac still good just the dirt block the air circulation

I just clean last week...and this model r410a inverter really give me alot problem....I I buy just 3 week then already spoil..now this Laguna geng. Got iced fly out..

Check if you have enough refrigerant/ leakage. Check also if you have dirty indoor unit coil.

And check the blower fan …

+1, my coil changed for this. Sleep and kiss by sliced ice at nite. WTF !!!

Since it is only 3 weeks old, bettter lodge your complain with Panasonic. get the complain ref no.
Ask them when they want to send their people over to rectify the problem. Follow up with an official complain letter. Keep records of all your complains to Panasonic. If you complain "hard enough" am sure they will act on your complain for sure.

may i know where the blower fan?can we open it and clean ourself?

Added on July 23, 2012, 3:53 pmsick air cond....in midnight time suddenly got sound clong clong clong then fly out pieces peices of ice to my bed....really a sucks air cond...pay rm1450 get a ice making air cond to put my room...if like that..i better buy a peti sejuk to put my room...this my last time on this lousy panasonic air cond...next time if got free i also buang longkang on that..

This post has been edited by nicky1112001: Jul 23 2012, 03:53 PM

The entire system screwed up might be due to 2 factor. The unit itself or the installation.

Ice making AC might be caused by several factor.

1) Coil dirty
2) Refrigerant level low

Since you have just cleaned it, cause 1 is omitted. Cause 2 is more like it. Low refrigerant can be due to poor unit or poor installation. If the unit is damaged before or after installation, the leakage will be detected if the installer is running on a proper installation steps. If he is following the correct steps, things will not happen like what happened to you now. They will notify you on the fault and rectify it with or without charges.

What you should do now is to check for leakage. Get them to hold the pressure of the system, then the piping, then the indoor, then the outdoor.

finaly they coming to check....guess wat i get?all the gas inside gone....no gas...funny things...special thanks that installer...somemore still dare ask me pay rm50 service and rm80 to pam gas inside agains...

sounds like a leak. even if pump gas it will still leak. best to reinstall piping or find and fix leak. A properly installed air cond shouldn't leak.

Places where leaks occur at:
fan coil - joint btw piping and blower
condenser - joint btw piping and compressor
piping - anywhere along piping

Barring aircond defect, problem lies with installation. If this air cond is inverter using R410a, it needs thicker piping (0.8mm). The old 0.6mm cannot handle the higher operating pressure of the R410a which is 1.6x higher than R22 meaning the thinner pipe will burst.

i dunno wat they doing..jsut see they clean my air cond blower inside and then say gas leak...then check where leak and fix then pam back that gas..

Looks like it's more to installation problem instead of the air-cond itself.

I just re-read your post to confirm that since its R410a, it's good to get a second professional installer standby after two weeks.

R410a gas cost a bit cos it's a mixture of 50% gas a, 25% gas b and 25% gas c. It cannot be top up just like R22 which is only a single type. Since the gas is costly, my guess is that your first installer fudged on installation causing a leak.

Re-read my explanation up in post #57 for possible causes. My guess is there's a leak somewhere.

A worst case scenario is if the installers didn't realize that they are using 0.6mm pipes.

Aircond forming ice most of the time means gas is low.

Nothing to do with the air-cond itself generally.
Aircond is not manufactured to produce ice, rest assure.

I won't be surprise if it did happen.

Many condo and apartment nowadays has pre-fixed conceal piping for air-cond.
So ensure the spec of piping is suit to the air-cond needs before buying.

Last time, my house renovation contractor screw up the Astro conceal wiring, they loop the Astro cable like ordinary electricity looping, causing signal loss across all the point.

Workmanship is one area one always to look at and forget whenever there is issue on air-cond.

I have 4 Pana air-cond that being used for 4 years daily until now, none has issue (touch wood), until now.

But one poor workmanship in installation that not tilting enough, cause some minor water clog issue from time to time especially when dirty time.

That's a clue and a very important question also which needs asking. New install over existing piping or with new piping?

On the bolded part, it is not entirely true but it is not wrong. R410a is a mixture with very very very very very very minimal temperature glitch as the boiling point of the mixture refrigerant is similar. As the boiling point is similar, the evaporation rate of each refrigerant is similar, hence there will be no one refrigerant is less in ratio than other. If there is leakage, top up on R410a is acceptable even if it is in 'commercial unit installation standard'.

However, it is often very hard to determine how much refrigerant is left in the unit. What installer will do in Malaysia is that they will measure the pressure of the system, using experience, they assume the remaining refrigerant quantity and add according to what they think is the balance. What Aussie will do is that they reclaim the refrigerant into a tank, weigh it, and top up according to spec, with the tank on a weighing machine. Before the recharge, they even do vacuum the system before re-charging. So if we are kiasi, we release the refrigerant (which is illegal), and recharge the full weight. Installer in Malaysia do not use the reclaim machine.

As for the piping thickness, some manufacturers specified 0.8mm because they kiasi and wanted to cover their own ass. I have experience in using 3/8 tubes with 0.38mmt and 1/2 tubes with 0.56mmt, with working pressure of 400psi, testing pressure 600psi. Operating pressure of these room air conditioners are lesser than 400psi. The worried point of why manufacturers wanted to use 0.8mmt tube is that they are concern about the flaring point crack, not the pipe burst. Poor flaring will result in a crack at the joining point hence leakage.

thks for enlightening! no wonder r410a so expensive.... it's also the labor involved. Is flaring point crack a common issue with many installations in the field?

This post has been edited by halcyon27: Jul 26 2012, 11:48 AM

I am not sure why R410a is more expensive but I believe it is because of the supply/ demand effect, Installers are actually doing the same thing be it with R22 or R410a. What they need is only need a different pressure gauge, different copper pipes, and a different refrigerant tank. They position, flare, bur, hook up, vacuum, open valve, on AC, touch, feel, pack things, done. They do nothing different from R22 units, so labour should not vary. But you know la, they bought special tool, they need to have ROI also ma.

Side note. If your AC's piping is not exceeding the standard pipe length, then additional refrigerant is not required. Check the spec of standard piping length and don't get conned.

Flaring crack at the tip can be very common. When they have poor installation skill or a poor tool, your flared end is not symetric. Looks odd and you will have visible or non visible crack. So after they joint it, you will have problem because that is the most vulnarable part to high pressure low ductality.

Same problem, newer Pana model. I'm not sure what the "sound" you have is, but for me (I don't reco this as a long-term solution ), a hard knock with my hand on the side (NOT the front) solved it, i.e. there was a loose or vibrating part somewhere. Grease won't help, get someone to check it part by part.

PS, a lot of people have the view that Panasonic products now are much lower in quality than they were many years ago. My old National fan, 20 years and still perfect working condition.

Most…if no all brand now manufacture/OEM @ world factory-china, National/=Panasonic so don't compare

In the 50s-70s, the west used to scorn Jap product = low quality. Now they know better. Even recent BBC article in the UK, top 3 most reliable car makes are from Honda, Toyota and Lexus. The conti rank among the lowest with Range Rover among them.

Who knows that China (and Korea) might become the next Japan in terms of quality. Lots of Japanese now working in China. The migration of highly skilled labour in an increasingly stagnant economy now going to where the boom is. Not just there but in Thailand, German tech and know-how are diffusing there. Cotto (tiles, WC, bidet, bath,etc) and Pimatec are some examples. Pimatec makes Pimaflex which I hope comes here. It would make aircon brazening a thing of the past. On the contrary, it might increase incidence of aircond theft.

There are still some skill set China even Taiwan find it hard to take on. Like car gearbox, how many do you see it manufacture from China? Mainly still come from Japan and Europe.

China is goods on manufacture because of cheap labor,soon they will lost the competitive. Take Malaysia for example we used to be good in manufacture same as Singapore and Taiwan. But we never evolved, now we can't compete with China for manufacture, and neither we can compete with Singapore and Taiwan for high tech manufacturing.

Or Indonesia?

I read an article about China. They are good in copying, but they only know how to copy the product and not the process. They copy the fast things the tangible things. They losing the own culture and value. They are just a production house now, and the real skill like handcraft are dying. They don't have many creative peoples. Not many artist, designer and skill people now.
This are the things and skill they need to copy to move to next stage. We Malaysia should too

I thought that is Taiwan..Every year when my boss and my team go for New technology exhibition in Germany, they have a big sign at the entrance "We apologize but no Taiwanese allowed"

Because they always copy other's machines and sell it at a much much lower cost and cheaper change parts, but the quality/accuracy is not there

If you notice, Taiwan and Malaysia have not been moving for some years.

My friend have a very good comment when he travel to Taiwan for holiday. Taiwan for holiday is good for Malaysia because they have not move much in the economy just like Malaysia so the afford level is like in Malaysia. Which I agree.

Will the germany write for China too.

China buy than reversed engineer it ;-)

Have you see the crv of China. Dam real from far.

China commit so many copy crime. But nobody dare to sue it.

With quantity comes quality.
China DVD used to last 1 month, Nowadays I switch on my China brand DVD machine on all the time hoping for it to rosak so i have excuse to change a new one ... still waiting after 4 years.

With quantity comes innovation.
China converting machines used to be cheap and quite basic, Nowadays their prices are going up up up, and the new machines output, percision, range are increasing day by day, even the west is using China machines more and more.

With quantity comes power.
Companies initially complained about China copying and kept their technology under wraps whithin their oun countries, Nowadays they are opening plants and even sub contracting manufacturing to China. e.g. Iphone to Foxconn in China.

With quantity comes acceptance.
Countries used to target China as their main competitor, Nowadays they all want to sell to china.

The sleeping dragon has awakened.

I m waiting some country to punish them. It seems like only US capable do that. Since they copy a lot of US product.

Us are afraid of them, because China is the largest US bonds hold. If they dump all the bonds US still go shock at least for few years. The money will be less than our boleh dollars.

Don't think the china that stupid. China will lost more than the US. Their money not their enemy.

Don't forget China is self sustain and also a communist country. They can do many things we think is not good.
Ah well way off topic.

Bought the panasonic inverter 1.0 model last November 2011. However, the funny thing happened was, halfway through (2-3hours after switched on), the 'cooling' was cut off, just normal wind blow. I've set the remote control manually instead of Auto. Any of you guys encountered such problem before? Or should I call panasonic again. The last week, the technician said it was because the gas was not enough. Troublesome betul.

Gas not enough is not because of the air-cond itself is good or not good. (unless it is air-cond internal piping issue, which generally less likely occur)
Gas not enough can be caused by leaking in between the piping, which is more related to workmanship issue.

So it is not fair to blame the air-cond disregard whatever brand.

Added on August 13, 2012, 10:57 amThe reason I said so, because majority air-cond problem I encountered were more about or caused by workmanship/installation issue.

i think i have to enlighten you on this. After panasonic sent their men over. Pumped in extra gas. Everything is good to go. Like what i told you earlier, 2-3 hours after the aircond was turned on, the cooling was completely cut off.

What i did later was to RESET the aircond via remote (pressing the AC next to the 'clock'). And the cooling gets kick back.

So, whether or not it is an installation issue. I'm not too sure.

same problem happened to me. Did you solve the problem?
they tell me it was because the contamination of the air quality was no longer. but I do not believe it.

Just an additional info.

I've had a Toshiba a/c for about 4 years now. And throughout these 4 years, I had to have a technician "pump in gas" for at least twice a year. Same problem, the a/c stopped blowing out cold air. Meanwhile, my National a/c in the other room has worked perfectly for 5 years and there isn't one day where this "no gas" problem has ever occurred.

But then, reading from the above posts, it seems like the "no gas" problem is caused by human error so..it all depends on your luck I guess.

Sometime is installation issue, sometime is copper hose issue, sometime is machine. Take time to identify.

After several attempts, the technician managed to find out that it was the 'control board' (indoor unit) that created so much trouble. Half functioning half spoilt, that's why even troubleshooting also cannot detect.

I have this Sharp Plasmacluster Aircond, 2 units. Both of them giving crackling sound that I suspect it's from the plastic parts, expand and contract and it can be very very luod sometimes, till make me wake up frmo sleep! The technicians come and tried to fix, taking off the parts and putting them back and they still make the same noise. THey ordered replacement parts but have never come after 2, 3 months!

So frustrated. Anyone experiences this issue? The noise comes even a few minuets after the air cond is switched off!

Does anyone know the reason why Panasonic aircond - EcoNavi timer blinks and unit just stop function...I am trying to on and off the aircond but after a while the timer blinks again and the aircond just stop functioning....Does anyone have the same problem and how to fix it?

i got poblem same like u.I also using econavi type.After switch on air con then half n hours it suddenly "off" itself. I repeat "on" aircon again n again but still same turn off after half hours. timer will blink after 1st "off" n i never set timer but it also blink.

call panasonic service agent come to investigate. They say is the air con gas leaking (between pipe and nat no proper join togerther). They also say econavi type air con off itself is to protect the compressor when no enough gas inside the pipe. Old type air con dont have this type off function and the compressor will continue to operate and last will spoilt the compressor. They ask me to contact back person install air con unit (contractor).

Tiger355, can't be leaking because my aircond with luck it function with cool air but most of the time...has the auto off and timer blinks faulty....I called the shop that i bought the aircond n they help me to log a report to panasonic. dunno whether they will come and check or not.

huh have to call back the contractor to fix the issue? the Panasonic guy cannot fix?

Did you problem solve after u had the contractor to fix it? Wat was the actual issue, did u ask the contractor?

Leaking also can give you cool air one.
It can result in freezing (not only cool )! if there is no enough gas (due to leaking).

Generally,
If it is installation error (piping leaking) is about contractor issue.
If it is air-cond issue/faulty then it is manufacturer warranty responsible.
