I would check the wall penetr*tion and be sure its foamed in. Next clean the coil with a mild soap and water mix. Clean the filter and see what happens. If still moisture, turn the fan speed up and see what happens. It's either too cold or too humid in my opinion.

These units are designed for precise cooling and humidity control. They are designed to run all the time. Although your cooling temp may be satisfied your compressor still runs maintaining that temp and dehumidifying as well. These inverters drop down to as low as 30% capacity and remain running which in fact is saving you electricity rather than stopping and starting.

If this is a central AC, the
condensation drips off the cooling coils into a pan. From the pan, it is suppose to either go into a drain directly or into a sump, which in turn pumps it into a drain. Dirt or mold frequently plug the drain out of the pan or the drain line itself. You need to clear the drain with a wire or forced air. If there is a trap in the drain line, it may be plugged. If there is a trap and the line is not draining from the trap into a sewer, then I suggest you remove the trap, which is intended to block sewer gas from coming up the drain line. If it doesn't drain into a sewer, there is no sewer gas to block and the trap is unnecessary. The credulous building code requires the trap, regardless of whether or not the unit drains into a sewer.

Likely have a bad wire. Sometimes you can swap a ground wire or line wire with the data wire and get it to work. Whatever you do outside you have to change inside. Make changes with power off.

Brahmadas, If you could provide the model and serial number of both the indoor unit and the outdoor unit this would greatly help answer your question.

Fixing and recharging air conditioners and refrigeration can only be done by licensed engineers. 'Freon' isn't used any longer, it R104 or similar. An engineer will use a spray to find where the leak is, fix it, suck out all the air, refill with Nitrogen, test for leaks again, then suck that out and refill with the correct number of pounds of refrigerant. It is the only way.
