I got this before. Daikin inverter. L5. Same symptoms. No cold air. After call technician say it's the board. Needs to replace. Ask how much almost same price as one bijik 1hp ac. I said fuck it. I'll buy a new one.

Yeah I didn't wanna fix it because what time my boy was a newborn. Couldn't afford time to repair and find a the cap replacement.

Straight away throw the damn thing bought a new one. Problem free since then lol

Up to you bro. I could afford a new ac. So I didn't care to toss it

Non inverter your bills will go crazy yo

If you willing perhaps can try to diy can refer to this vid

Hi I stumbled into this thread looking for this error code from my AC as well

I wonder which model are you guys using?
Mine is the "Infinity" Series, R410a
Mine was installed Dec 2017, so almost 6 years ish
Now is also getting the L5 error

And if I do end up going with replacing it entirely, what brand do yall recommend since I don't want to go daikin anymore

EDIT: Here's the thing, it sometimes works and it sometimes doesn't
I noticed it prefers working while the weather is cold (rainy/ night)
Where as in the afternoon it does not want to work
I have had a technican come and take a look
they checked, said gas is ok
did some cleaning, which did help it keep running fine for like a week or 2
and then now the problem is back again
