I just fixed my GE portable AC unit. I only had it for a month and it started displaying FL. The manual with it was pathetic. But, I cleaned the filters and took the drain plug out of the condensation tank which was completely dry. I put cleaned filters back in, plugged it and it ran a few seconds and flashed FL again. I let it set awhile like one website suggested in case it was froze up. That wasn't the problem. Let me make it clear right now that I am a technician. So I took the cover off and started troubleshooting and I found the problem right away. The float switch in the condensation tank had literally snapped off the poorly engineered mounting and was laying in the bottom of the tank. I fixed mine with some super glue. This was clearly a planned obsolescence that kicked in to soon and I wouldn't doubt that many other units have the same early failure. My advice to you, if you have a similar FL code that won't go away, is to tilt the unit back and forth and side to side and listen for that loose switch to move around in the condensate tank at the bottom of the unit. That may be the problem. If you just bought it, take it back to the store. But, don't take the cover off unless you know how to work around electricity. The repair is very simply for a technician with some tools and superglue. But, it's not safe for you to do.

Call to LG service center. Masters will help you.

no freon or compressor internal failure

Brown and yellow usually go to the motor. (Red and black wire to the control box - red usually attached to "C").

The should be a wiring diagram on the back of the refrigerator.

hi im notice you have a red light on the panel for filter.is the filter clean?.clean it then do a filter reset

Inlet pipe temp sensor short. Order and replace!!

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.

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.

It seems like it's short cycling. The condensor motor runs when the compressor runs,
Probable cause, no airflow thru the condenser, low on refrigerant, wrong location of temperature sensor,

Sounds like it maybe a refrigerant charge problem. Do you have access to refrigerant gauges? Do you also know the model and serial number?

It sounds like the receiver unit in the control board is not working. What is the model and serial number?

Sounds like you may have gotten something wet that shouldn't have during the coil cleaning process. Power unit sounds to be working, but control board may have been damaged.

Blower wheel maybe out of balance, loose, debris trapped inside, and faulty bearings on the blower motor.

To cancel the Sleep Mode, press the sleep Mode Auto button several times until the star disappears from the operation display.

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.
