GE AJCM wall air conditioner not removing humidity
A few years ago, I replaced four 2nd-floor wall air conditioners (the wife was balking on ductless AC) and they all work fairly well, except for the one in the master bedroom. It cools but doesn’t seem to be removing the humidity from the room. I believe it’s sized properly (9000 btus for a 250-300 sq ft room). I’ve also noticed it’s the only one that I can hear the fan hitting water when it starts and when it’s running.
Could poor drainage be an issue? I can’t even find where the unit drains.

If you are hearing water...... the A/C is dehumidifying.
Most air conditioners have a slinger on the condenser fan that slings the water up and onto the condenser coil to help cool it as well as get rid of excessive condensation. Usually when you hear the water sloshing it's because it's either not getting to the slinger or the level is fairly high. It could be a clog in the drain pan but more likely the unit may not be tipped down enough on the outside for the water to flow outside.

That’s the part of the problem: I can’t find where this unit drains. I’ve looked in the manual and there’s no diagram, nor can I find one online. I’ve cleaned out the unit and can’t see where the water is supposed to drain out.
That being said, does it make sense to make my own drain?

There are two sections of the drain pan. Towards the front is where the evaporator water drips into the pan. Then there is a small channel where the water runs from the front section to the pan outside. Once the water is outside.... the fan will sling it up and get rid of it. The water is probably backing up in the front part of the pan.
At this point, I am not sure where the problem is. Perhaps the AC disconnect is faulty and/or the wires between the panel breaker and the AC disconnect are damaged. Or perhaps the voltages between Line 1 and Line 2 are in phase so that I measured 0 VAC. Please let me know what you think. Thanks in advance!
