Samsung AS05XLNXSE Blinking Problem

[Bullz]

Hello Refrigeration Masters,

I want to ask my AC, its Samsung AS05XLN.

Several days ago, suddenly it stop working and closing evaporator blower discharge, and there an indication that operation and timer LED blinking in green light.

Sometimes, it can run normally again :cool: and sometimes it gets error like above described again. :mad:

I had searching in this forum, and i found some Paul postings, and I have conclusion that my AC has problem in "Indoor unit heat exchanger temperature sensor error (open or short)" and the main checking point is "3-3P"

So, I now know the cause, but how can I fix it?
I don't know what is it 3-3P main checking point?

Thanks for your answer :)

1. Check the assembly condition of the sensor connector (CN43) on the indoor unit main PCB and if not assembled, reassemble the connector accurately.
2. Detach the room pipe sensor connector (CN43) and check resistance between connector 3 and 4.
Temperature(°C) Resistance Value(Kohm)
15 14,68
20 12.09
25 10
30 8,31
35 6,94
40 5,83
The data tolerance is ±3%.
If the above data is not met, replace the room pipe sensor.
3. Assemble the room pipe sensor to PCB, plug in, and check the voltage of connector 3 and 4. If below 0,5 V or over 4,9 V replace the indoor Main PCB (short or disconnected in the PCB board).
