Some times water will not drain out right need to clean the drain pan, blower wheel will also catch dirt and build up mold. The front cover should come off easy, there should be three screws on the bottom and it should pop right off after that, exposing the pan and blower wheel . Clean as needed.

Could be your capacitor in the outside unit. If you have the right tools and are experienced working with high voltages then you can test to see if that is the problem.

***CAUTION***

Anytime you are working on or around electricity you run the risk of shock and or death. If you are not competent working with high voltage and using electrical test equipment, please consider consulting an expert before you open an electrical panel or appliance. You assume any and all liability by continuing with this diagnoses process.


***WARNING***

Capacitors hold a large electrical charge even after power has been removed from them and will discharge upon contact with your skin. This is enough to stop your heart and cause death. If you are not confident in your abilities to work with these devices then please leave any testing or repairs to a professional.


The capacitor is inside the outside unit and you have to remove the cover to see the inside of the electrical compartment. You will need to discharge the capacitor before you start working around it. To do this take a screwdriver or other long metal tool with an insulated handle and cross the three terminals on the capacitor to ground. You then remove the wires to the capacitor terminals, taking note of which wire goes to which terminal.


Capacitors are rated in Micro Farads (marked by a µF symbol) and a dual capacitor, shown in the image below, will have two ratings listed like this "35/5µF" or something very similar. You must have a multimeter that reads micro farads " µF " to check a capacitor.


You do that by placing one probe on the C or COM terminal and the other probe on the FAN terminal and it should read the small number of the rating, for example if your capacitor is rated like this: 30/7.5µF then the fan rating will be the smaller of the two numbers. In this case the 7.5µF (seven and a half Micro Farads). The HERM terminal is the one for the compressor and will be rated the higher of the two numbers, I.E. the 30µF on the capacitor. Check them both and of they are more than 6% lower than they are supposed to be then the capacitor is weak and needs replaced. If you read 0 (zero) then the capacitor is bad and needs replaced.

You can't charge on cool mode as your indoor temp is very lower than minimum temp of air conditioning. ., 16 C degree. And also due to low ambient temp your coil is getting freezes. Keep in heat mode and check still icing your coil, it's short of gas. And that time you can do gas charging by keeping cylinder up right. Helpful?

Hi,

There is either a problem with the outdoor unit fan or compressor or there is a communication problem between the two....

Did you check the number of blinks and then check the book to see what it means??...

Hi,

There could be few reasons for this error :-

1. Refrigerant leak or shortage of refrigerant.
2.Indoor unit heat exchanger sensor [ThiR] is defective (short circuit).
3. Indoor unit PCB defective (defective sensor input circuit).
4. Indoor unit PCB defective (defective sensor input circuit).

A tech is recommended for the exact diagnosis of this error.

Good Luck!!

Thanks!!

That should cool up to a 60 metre squared room. I would have the room measured up by a professional and they will also calculate heat loss and recommend the right unit for the job.
Hope this helps I take the time to help you so please rate me
