Hey guys, need your help.
My Electrolux Air Conditioner displaying H3 error code.
Meaning compressor faulty? Or compressor overheat?
How to solve this?
Just happened at midnight and I will check again later. According to New MCO 3.0 SOP, is technician allow to fix and repair air conditioner at customer's house?

Error code: H3
Error name: Protect against compressor overload

Could be the run capacitor died. Its a quick fix if you can access the ODU safely..just open up it will be like a big beer can or two, and buy similar uF one online. Important: familiarise urself with capacitor handling procedure i.e. Discharge old one before touching.

SOP refer https://forum.lowyat.net/topic/5148398
Some highrise MO need to see paperwork for recent virus testing.
Although the test is pretty pointless (morning go test, afternoon infected, night result negative) as its historical and not realtime.

Hello, thank you for the quick response. Is it expensive to replace the part?
The air conditioner is around 5 years now. I remembered around 2016 fix in the shoplot.
We fix in the shoplot then later transfer air conditioner to my sister's room.
Repair or replace air conditioner in this scenario? Is this error code H3 very common or rarely happens?
Thank you for the quick response as well.
Last midnight happened this, then no cold air coming out.
Spray the water to left or right side of the ODU?
If right side not possible as the space is very narrow and it is blocked by the wall.
Just tried switching on, H3 error code still there with the operation light blinking.
I told my sister to switch the main power and check again later at 12pm.
Thank you for the quick response as well.
Last service date was 23rd April 2021. Normal service like without dismantle the whole unit down.
Just take out parts one by one. Clean the filter, indoor unit cover, swing blade. I guess the fan didn't clean.
I will check with my condominium management and the technician afterwards.

I tried many times still same. I switch off then wait for 30 minutes then power on via remote control.
First few minutes like normal then after a while H3 appears and cooling light symbol blinking.

likely the run capacitor then.

Hello ceo684 ycs slimey mini orchard

Some updates regarding the Electrolux air conditioner.
Called technician to fix, wash the outdoor unit with water and vacuuming does not fix this issues.
I think I guess will install a new one better as the technician cannot find what's the issue over there.
Wasted my RM50 and the issues still come back.      

Today start lockdown for whole Malaysia. As technician not allowed to fix air conditioner during this period.
Panasonic released new X-Premium Inverter model which is CS-XU10XKH-1.
Got one shop quoted me for RM1849 without installation. The Save 2.0 suddenly open back for a short period.
Final price will RM1649 with the Save 2.0 promotion from the government by claiming through TNB part.
So should I reserve for full price without installation now to claim the RM200 off from the government?
As I might afraid that Save 2.0 aka RM200 off will end again.

The new model comes with built in WiFi which is a bonus for me.
I wish to get the CS-XPU10WKH-1 model but no left right auto swing.
Last time I bought Daikin FTKU series but haven't claim due to quota finished and now open back again.
Now the shop told me Daikin temporary no stock. Luckily get one for my room before OOS.
Now is my sister's room suddenly display H3. No idea the problem comes from where.
Don't wanna waste my time and money when the H3 display again after fixing.
Not only showing H3 error, left and right motor swing also spoil, can hear clak clak clak sound when auto swing.
The technician last month came said no spare part. Gonna let it go I guess. About 5 years like that.
Can't remember which year that I bought it. MCO making me headache to see Air Conditioner out of stock everywhere due to global chip shortage

Anyone using the latest Panasonic ones already?

I'm living in Penang. So not possible get that price.
I check variation of that price RM1799 excluding installation.
But if apply and deduct Save 2.0 voucher will be cheaper. .
The technician brought and test using refrigerant meter to test.
In the end mention outdoor unit thing dirty.
We told the guy display H3 error. Don't want to waste my time if the next technician cannot fix what's the issues.
Will try to use up the Save 2.0 voucher. Can save RM200.

Yalor. It's better for me to get a new cause if no spare parts or issues come back after repair.

Yup, don't know how to explain the issues to the technician already.
I guess is not Electrolux, should I call Electrolux instead of normal technician after the lockdown?

Need some expert advice.

May I know what is those white spot? It looks like ice for me, but I turn off my aircon before morning, and I check evening still can see this. If is ice it should be melt after some times.

I wonder is my additional filter cause the air flow problem. I will remove it and monitor.

CAUTION! This morning my neighbour was trying to replace his ODU capacitor and it exploded on his hand...so loud noise, I immediately jumped out of my chair and run outside to see, looks like all his fingers were all disintegrated...
He was in shocked. His mother sent him to hospital already. Dunno what happen next. So becareful guys, don't DIY replacing capacitor if you dunno what you are doing. I will try to upload some photos of the incident later, if allowed by the neighbour.

He didnt discharge the cap properly before handling. All AC cap still got residual charge inside. Should use one of those old 60W or 100W hot bulb to discharge.

Personally i don't condone using screwdriver to short out the cap. A resistor-based cap discharge tool is best, or just hook up one hot tungsten bulb will be enough to discharge it.

I see, thanks for the tip

Oh btw, usually every year( plus minus) my AC would leak water and the drain pipe would be clogged with jelly like substance, is there a way to clear the jelly away?

Hi sifus, recently my aircon broke down. It was blowing normal/warm air instead of cool air.

I noticed that the compressor fan is still running, and the compressor sound is softer than usual.

It is an old aircon 1.5hp Panasonic aircon (CS-PC12EKH)... probably more than 10 years already. I managed to get someone to check. He told me is it time to change the whole aircon even though he has not done any checking.

Is there anything that I should or am able to check first?

It was never confirm it was the capacitor malfunction but a mere speculation. For an experience AC technician, changing capacitor is easy money job compare to installation of new AC.
