Hi,
My AC is not working. It had been working fine yesterday and this morning. It currently is not working and it flashing lights:
Operation light: 10 flashes
Timer light: 1 flash
Economy light: continuous flashing
I have pressed the reset button and has not worked. I have also checked the manual and have not found any solutions
Any help would be much appreciated
Thank you

I need model name;)
is the indoor unit or outdoor unit work
From the fault code description with a flashing economy light (also green) then I guess this is a newer model with standardised fault codes. Model for outdoot would be AOTG... The G is the important part here to signify I am on the right track and the model is the newer generation.
This code is discharge temperature error - meaning outdoor PCB has determined that discharge probe has gone over 110*C twice in 24hrs.
Commonly caused by low refrigerant charge but there can be other causes.
Of course a model number would confim my detective work here.
Cheers,
Sherlock Holms.
Hi
My apologies
The model number is ASTG24LVCA
The indoor unit turns on and flashes, no air flows through at all. The outdoor unit, the fan doesn't spin. (I thought this was because the indoor unit didn't work properly, but have no idea)
Definitely need to take the advice of Tayters but then you need a serviceman.
You can check cleanliness of outdoor heat exchanger at user level.
If you turn the mains power to the whole system OFF for 10 minutes and then back ON again, will the system start?
:cool:
Thank you everyone :-)
I have no idea what this means:

I did clean the filters and had it turned off for minutes after cleaning. It worked after I did this.
However, yesterday I did switch the power on and off at the circuit board a number of times and did this not work. Why does the amount of time it is switched off matter?
Thank you to everyone who replied, much appreciated :D
The theory is that if the system hasn't got power for a couple of minutes, when the power returns the system will do a full reboot.
So if it is a fault that requires a sensor to reach a preset temperature twice in 24 hrs, the system would start up and run for a short time. If the system doesn't start up at all it is likely to be another fault.
If you are competent and confident to open up the outdoor unit you can check the temperature (using a good quality digital thermometer with suitable probe) of the compressor's discharge pipe as close to the compressor as possible, this is the smaller pipe connected to the compressor. When the system is running normally and for at least 15 minutes before you take the reading this should be below 100*C (normally you would expect it to be below 90*C).
If you find that it is operating above 100*C you can tell your service technician that the system is most likely short of refrigerant and if it is running below 100*C ask him to bring a new discharge sensor.
:cool:
The Viking said that the power should be turned off for 10 minutes or more. it is necessary for full discharge of electrolytic capacitors into outdoor unit.
And needed cleaning outdoor unit.
It is good that it not J series of the equipment.:D
Ahh I see :)
Unfortunately I can not get to the unit as the landlord has put it in a cage. I can see the unit etc just can not reach it.
The air con is working fine after cleaning filters and switching off for 20 minutes. Would the service man still be able to pick up if there is a problem with the outdoor unit? (keeping in mind it has been working for 24 hours now)
I assume that cage prevents air circulation
and during maximum solar energy the outdoor unit have overheating.
the cage is just a metal cage to prevent people tampering with the unit, airflows through it --- like a heavy duty wire cage
Do you can upload photos with installation of outdoor unit?
I can't, it's in a cage with some other units
I had this recently - a near new unit, used almost exclusively in cooling, would fault in warmer weather.
All thermistors checked out ok, temps ok.
The only solution available was to replace all electronics in the outdoor unit.
No further faults so far - but then again, it hasn't exactly been warm since.

I dont need the focus on your unit I need a general view.
