    my air conditioner split system leeks water inside from the unit

    Could you tell me why and what to do to fix it

    Ice is forming on the indoor unit radiator, and even when the outside temperature is around 25 degrees Celsius the unit isn`t able to lower the inside temp. below 23 degrees Celsius. The symptom is manifesting at any given outside temperature. The heating mode is working properly (done also by the compressor).

After I replaced the pcb on my samsung air conditioner indoor unit it won't start and all 3 led's are blinking

I have had similar problems with Samsung. Apparently, the indoor board fits a lot of different models and each has to be "programmed" in to suit your model. Not sure what was wrong with your machine before but it has been known for these units to have a faulty outdoor fan motor which causes the outdoor board to fail as well. When this happens, the indoor unit will usually work fine for about a minute or 2 and then shut down, with lights flashing. The outdoor wont start at all. If these were the symptoms, I would suggest putting your old indoor PCB back and then getting a new outdoor fan motor and outdoor PCB.

Remove batteries and replace with new batteries and restart. If still problem, unplug DC wire to indoor display sensor and plug it after a minute. Now try with your remote. If still problem, try with another remote. If no result, PCB receiving sensor defective. Replace display sensor or PCB
