I have the same problem too. Aircon cannot switch on, two lights from the top is blinking. Everytime I turn on, the flip is open then close again with sound. The technician said the thermostat cable need to be replace. It cost about $15. The cable is 14" long. Hope this help.

SOURCE: I have a samsung silver nano...the indoor unit

  • Ensure Air Filter is clean - clean as necessary
  • Ensure Evaporator coil is clean - clean as necessary
  • Ensure Condensor coil is clean - clean as necessary
  • Inspect all wiring inside the unit for any loose or damaged connections - correct as necessary
There could be a failed compressor relay, run capacitor, or compressor motor/valves. Of course, it could also have lost it's refrigerant charge.

Without being onsite with toolbox in hand, I hope you find this information to be very helpful moving forward. :-)

Hi clawrence001,

I believe the main fan may be overheating. I'd inspect it first. Normally these fans can be hooked up to Amp meters, if the Amp reading is higher than the specified ranges on the motor, then the motor is faulty. Be sure to also thoroughly clean the unit when opening it. Poor ventilation can lead to overheating.

Kind Regards :-)

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.

When we turn on our split AC, outside unit is not turning ON


The blinking light is because the unit is waiting for the outdoor unit to come on. If in heating mode, the indoor fan will not run before enough pressure and therefore heat has built up. You should check that the indoor air return sensor is not faulty and therefore preventing the outdoor unit from coming on.
