Samsung AC is not cooling
Hi,
I have a Samsung AC model AQ12FANAFR, after an electric sudden cut, it stop cooling when i set the indoor temperature below room temperature, no alarm was showing (no LED blinking). the technician suggests it is a sensor issue, so we borrow the sensor from other similar unit and replace it, then the compressor works well when choosing cooling mode. so the technician purchase a new but non-original sensor and replace it, unfortunately it doesn't work, then i bought the original one from samsung service center but didn't not function properly after installation. However if i use the heating mode, it is OK and when i turn turbo button it starts cooling for 30 min then the compressor go off. in cooling mode the compressor doesn't start at all.
Please help, does it need a reset or PCB got damaged when he used the wrong sensor?
Thanks in advanceLast edited by lebmfk; 27-05-2017 at 10:56 AM.

Re: Samsung AC is not cooling
i think its need programming by Samsung service center
Power consists not in being able to strike another but in being able to control oneself when anger arises

Hi LEBMFK,
My thought is that the 'non-original' sensors are the incorrect specification.
All the indoor unit sensors are the same characteristic - here's a guide
0°C = 27.3 k ohms
10°C = 18.0 k ohms
20°C = 12.0 k ohms
30°C = 8.3 k ohms
40°C = 5.8 k ohms
I suggest checking these readings against you unit.
Also if you think your AC needs to be 'reprogrammed' ask your local Samsung office for the product code. We do not have this model in the UK so I cannot help with this.
