HELP! Samsung ASV13PSLNXTC

[rudog]

I need help with my AC unit guys.
It's operational but it's not cooling.

I have read from other threads that it may have been
caused by power fluctuations which is pretty common
here in the Philippines.
The first time this happened the repair man came over
and pushed some buttons on the remote and it worked.
But, as I've mentioned, power service sucks in here.
So, I'm dealing with the same problem again.

What shoud I do?
Is there any manual for this?
Reset codes?

I'm trying to stay away from the service repair bills if
i'ts fixable by only resetting the unit.

Thanks in advance!

You say it is operational?

Indoor fan runs? Outdoor fan? Compressor?

Any flashing LEDs on the indoor unit?

If everything operates and there are no flashing lights then unfortunately a code will not help you, you will need to get your service guy back in.

If on the other hand it doesn't operate or you do have flashing lights, please let us know and I will see what I can do to help.

Outdoor fan is not working but the indoor fan is.
No flashing lights visible.

Samsungs can be a pain in the butt with fault codes in my experience.
Can you makes sure that the system is set in cooling mode, and the set point is 16C please?
That'll force it to ask for cooling if your room temperature is anything above 18-ish.
Hopefully then it'll give some flashing lights, but it may take a while.
The last one I did was slightly short of refrigerant, and only intermittently gave a fault code as the room temperature was generally comfortable.
Look for oil around the flare nuts first, then oil anywhere else. Any sizeable leak will normally make itself known with an oily patch.

Thanks guys! I appreciate all the feedbacks.
But it's still not working.

Had the service tech come over earlier today.
He said the mainboard of the indoor unit needs to be replaced.
Not relaying / distributing enough power, he said.

Any comments on that?

If he's right, how much would that mainboard cost me?

Thanks again in advance.
