So I know my issue is that my drain line is clogged. The unit is constantlye dripping water fro the front and I can see standing water in the pan. I am trying to remove the drain pan from the inside unit to get to the actual drain line but all I can find online are demos showing Mitsubishis or some other brands. They all seem pretty similar and a couple of videos got me about 90% there but I cant for the life of me figure out the last 10% and how to remove the pan or at least get to the inlet of the line.

Anybody have any experience with ComfortStar brands specifically and want to shed some light on the subject for me?

The only model number I can find is on the outside unit and it is CPG024CD (0)

TIA

I'd find a way to clean in place. The tight confines on mini splits make it easy to crack the pan.... shop vac the drain line and see if you can get a compressed air nozzle with a rubber or other small tip in there to stir things up while the vacuum is running. and before that, spray a weak bleach/water mixture on anything that looks dirty.

Yea. I tried that but the actual drain line doesn’t seem to be accessible from the unit itself. The shop vac didn’t make much headway either. I’m going to try to find a more powerful unit and try again but I fear I’m going to have to end up removing the pan itself to get to the line.

Can you drill a hole in the pan & add a new drain line in a place with easy access?

I'm not sure what you meant there. I was describing getting on the outside discharge of the drain with the shop vac and let it run, get a good seal with a rag, you want all the air coming through the drain, then go inside and see if you can blow, or even wash the coil and pan towards the drain outlet. If the thing is flowing at all you will hear gurgling as the water/ crud gets sucked into the drain. If you can get it to do that, and then give it a good rinsing with the weak bleach, that should break free any cold water slime or other buildup. I wish I'd had a cell phone back in the day. I've had drains that looked like a clogged artery.

Sorry, I meant that I tried the shop vac from the outside and it didn’t help. It wasn’t a big one so I’m going to try to find a more powerful vac tomorrow. What I meant by not being able to access the drain line from the unit was that I can see exactly where the line comes into the inside unit but there doesn’t seem to be any way to access that spot specifically. It would have been so easy to just have a removal cover to access it for easy cleaning. I say that because this unit can be set up with the plumbing on the left or right side and mine is on the right. Well wouldn’t you know it, the plug for the drain line on the LEFT side is right out in the open!

And as far as I can tell the only way to access the drain on the right side is to remove the pan. I even tried to use one of those little orange and yellow hair removal “snakes” and just get as much gunk out as I could and that didn’t seem to help either.
