Inverter AC and Everything about them

[HellsGuardian]

Yes it is a 30-40 year old no frost made by Sharp corp Japan. I searched its model number but nothing comes up on internet lol

I am aware of defrost cycle but why would it last like 2 3 hours? The refrigerator looses all its cooling in these 3 hours, the ice cubes also melt so such long defrost cycle seems abnormal. If the overload is cutting off the circuit, why would it take some many hours to cool down? or is it normal?

It is highly possible that previous guy overcharged the refrigerant but when it is running, cooling is great. One thing i noticed is that the thermostat dial is loose so perhaps it is set to maximum cooling so after running so long, overload finally cuts it off.

The compressor has been changed once few years ago so probably the electrician did some juggarri work. The rear casing has a circuit diagram and i tried tracing the wire and found that it is not exactly like it should be. Also for some reason electrician removed the capacitor whereas it is present in diagram.

Too many things to narrow down, i have some experience with basic household electric stuff but refrigerators are above my level lol I am new in Lahore so don't know any good electricians... I have tested 2 3 electricians but all seem to lack basic knowledge and always in a hurry to leave for next job.
One guy did not even remove the packing material beneath my samsung washing machine, and said k sir acha hai zameen pe paon nahi lagenge machine k! And this packing material fits between drum from underneath so the drum was never on its shock absorbers
Another guy while replacing a water motor made opposite connections i.e. connected suction side to outgoing pipe (it has a one-way valve)
Another guy as mentioned previously just changed the relay and overload and finally concluded k masla stablizer ka hai.

Hehe my shitty Haier fridge started doing it after first 2 years, doesn't do it very often but when it does it's down for atleast 5-7+ hours and releases too much water.

F8 error coming in display of my 1 Ton Electrolux split A/C

Can anyone guide me how to deal with this F8 error coming on display of my electrolux unit? due to this error, A/C stops working all of sudden and sometimes this error comes after 20 minutes of start and sometimes comes after 2 hours sometimes after 5 minutes...so no exact time for occurrence of this error.

I called A/C shop near my house, he came and took Circuit with him, told that there are some error codes so he reinstalled after 2 hours but still this F8 issue persisits......

Haier---------Scrap brand-------Poor Cutomer Service
I am also highly dissatisfied with the performance of Haier products....I have bitter experience of Haier split A/C so @usman19854 your Haier product complained little late as mine went out just after 13 months and to top of the hell, pathetic and corrupt Customer service of Haier

[usman19854]

Ya Haier is shit

My both Haier ac's have had some 30-40k+ spent on em after various issues turning up, aik evaporator Ka masla har Haier ac mein within 1-2 year ajata hai.

Refrigerator is also shit, produces so much moisture inside that vegetables get bad within a very short period of time. After a few days turns off and releases hell lot of water for some 5,6 hours and then turns on itself -,-.

I think they pay shopowners to portray their products and support as best whereas both their products and support are completely useless.

@usman19854
I am 200% agree with you. My split A/C also took around 20K+ within a year(Covered under warranty) & now again 15K expense due to poor quality

Sad part is i bought by thinking that it would be inverter so it will be economical, quiet so i bought for my parents but in fact ashamed and guilt of this wrong decision. I think Orient & Gree would be much more better decision than this
even i think Pakistani brands like Dawlance are much better

BTW nowadays i am also worry for F8 error in my electrolux

[HellsGuardian]

new series launched by dawlance looks really good! they are offering 12 years warranty and all the new features that others are offering. Also dawlance has been acquired by some other foreign company so things looking good.

[usman19854]

Yh idk how are they making appliances, previously we've owned appliances of different companies like general, sg, Samsung and most of them gave worry free service for easily 10+ years. I'm literally surprised at how bad Haier products are quality wise :-/

[usman19854]

Yeah they've been acquired by Arcelik that owns various brands throughout Europe so things are looking good for dawlance and 12 year warranties are really great, I plan on replacing my Haier products, especially refrigerator with dawlance.

Hey @brownrose78 have you cleaned the AC filter? Some ac's show this every 335 hrs after filter is cleaned, try it.

It can also be a leak inside tho.

Also found this
There's a site called fixya where many ppl have replied to this question, go through those.

Try to remove plastic cover/body of the indoor unit, there you may find a sticker with all the error codes and their meaning.
This way you will also have a chance to properly clean the indoor unit. The plastic body is generally held by 4 to 5 screws concealed under body colored rubber inserts.

Error codes list sticked on inner side of the plastic body of my Panasonic K18PKF inverter AC.

the defrost cycle should last no more than 20 minutes, there is a timer for it - and once that timer goes bad, this happens.

The timer should be in the refrigerator cabinet near the thermostat. you will need to remove the thermostat panel to see it. Its a mechanical clock - which should have a screw that can manually rotate the clock. Once the compressor goes off - try advancing the clock after 20 minutes to see if it switches on.

if your run capacitor is missing from the circuit the compressor will overheat from the higher amp draw and trip the overload. Make sure the cap is in place.

Im thinking that your timer is functioning but your compressor is switching off due to the O/L - check the wiring diagram and use all the parts listed on it.

Lg heaters works nearly 40 minutes after every 7 hours running of compressor.

[HellsGuardian]

Thanks for a detailed information. I will check the mentioned points!

One question though, if compressor is cutting off due to O/L, then why would it take few hours to cool down? is this normal to take 2-3 hours for O/L to close circuit again?

How many amps should 1.5 ton inverter used after 7 to 8 hours of running?

[imranabid4301]

I mean units not amps

[Xulfiqar]

yes, it may take that long.

I am planning to purchase Inverter split AC. The room size is 10x15 and the room does not get direct sunlight for long.

I prefer to go for good brand like Panasonic. The 1 ton model (CS-S13RKH) is available in karachi for RS.75000. Based on technical specs and the refrigerant it uses, I'm more inclined to go for this brand.

I need opinion as to how good is Panasonic in terms of cooling and energy savings. I checked LG Dual inverter 1 ton but it's energy consumption is higher than Panasonic plus the international reviews of LG is not so positive for the model available here in Pakistan.
