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. :-)

SOURCE: Hi I a have Samsung

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 :-)

Toshiba air conditioning unit not working RAS-13UKH-G

If the operation light is blinking, it means there is an error with the unit. The number of blinks can indicate what the error is.
Here are some common error codes for Toshiba air conditioning units:
  • Blinking once: Indoor unit room temperature sensor error
  • Blinking twice: Indoor unit coil outlet temperature sensor error
  • Blinking three times: Indoor unit coil inlet temperature sensor error
  • Blinking four times: Outdoor unit discharge temperature sensor error
  • Blinking five times: Outdoor unit suction temperature sensor error
  • Blinking six times: Indoor unit EEPROM error
  • Blinking seven times: Outdoor unit EEPROM error
  • Blinking eight times: Indoor unit remote control error
If you can determine the number of blinks, you can refer to the user manual to see what the error code means and what steps you can take to fix it. If you don't have the manual, you may be able to find it online or contact Toshiba customer support for assistance.

What p6 error code mean on a senville aura minisplit

I have an 2 zone outdoor unit. 2x 9000 btu Aura indoor units. Both on 16ft lines. When i installed the first indoor unit and ran the setup the system would shut down every few mins and then restart after a while. Error code P6 would flash and the run and timer lights would alternate.
First assumed a defective compressor or so but after hooking up 2nd unit it went away. Seems that hooking Both units up to a 2 zone is required otherwise the compressor sends a fault code P6.

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.
