Hello, usually this can be caused by either a dirty filter, evaporator coil or low refrigerant charge.

Your AC removes humidity and cools the air, in Dry Mode it cools the air but does not remove the humidity as much, which is OK in a desert (Las Vegas, Arizona, etc.) but not good for caribbean with the high humidity

Hi,

I would advice you to clean the condenser coil by condenser coil cleaner and its aluminum cooling fins for efficient heat dissipation. Compressor has a thermal overload protector which will turned off the compressor once gone to excessive heat. This is very common problem on summer which will increase the heat build-up of the condenser and compressor that activate the thermal fuse, when the compressor is not running consistently the evaporator coil will not cool enough even you set the temp to high cool. Proper cleaning of condenser coil and its cooling fins can resolve the issue.

If the symptoms still persist, this is an indication that the system needs of refrigerant charging. This is not DIY and you need an assistant of a technician to do the job.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Your drain line seems to be clogged, after a while the build up of dust and moss etc clogs that line and occasionally needs to be cleaned.

I wish to tell you it is not that easy. It is necessary to have aset of guages and know what they mean . I would hate to see you over charge your unit ... its best to call aservice guy for this but you can if you wish .

TRY RUNNING THE FAN SPEED ON LOW

how do you know the freon leaked out?

Its going to take a hile to cool down a hot room . have you cehck the filter? while your at it wash it out . what is the temp of the room and the temp of the air coming out of the unit?

If this is a window unit tilt it toward the out side more

the coldest air would be low .. BUt you need to set it to high or it will ice up

Here's a link to the Owner's Manual for your AC unit. You can download and print it for future reference.

YOu have the temp set to low.. they need to shut down every now and then to kinda deice. Check the filter as well . lose off rooms that are not in use during the day. But my guess is that it's set way to cold.. you will also have to shut it down for a hour or 2 and deice it.

Sounds like you have a 220 volt air conditioner plugged into a 120 volt outlet.This will cause the conditions you are describing.
Put a filter on it please.
