Moving on, this is a list of Indoor and outdoor detailed inspection procedures for Samsung mini split error codes. This is made for users to follow to determine what is wrong with the AC.
Indoor detailed inspection procedure | |||
SN# | Process | Inspection method | Causes |
1) | Pull the PCB out of the control box. | Is the first fuse disconnected? | Overcurrent |
Ensure that you plug the PCB is plugged out. | Is the second fuse disconnected? | The indoor Fan motor is short | |
Check the fuse. | AC part and pattern short of indoor PBA | ||
2) | Check Supply power | Check the power voltage | |
BD71 input voltage 200Vac-240Vac | The power cord is full, open fuse, wrong power cable wiring, AC part is faulty | ||
Voltage between terminal IC02 pin #1- #2 12VDC | Faulty Switching trans of Power Circuit | ||
The voltage between the terminal of IC02 pin #2-#3 5VDC | Load short, power circuit is faulty | ||
3) | Press the On/off button | Voltage over AC 180V imposed on terminal #3-#5 of fan motor connector CN72 | The Fan motor of the indoor is faulty |
Fan motor of the indoor unit doesn’t run | Fan motor connector CN72 is faulty | ||
Power voltage between terminal #3-#5 of the connector CN72 is 0V | PBA is faulty | ||
Outdoor detailed inspection procedure | |||
SN# | Process | Inspection Method | Causes |
1) | Pull PCB out of the control box, and ensure the PCB is plugged out. Before you check the PCB fuse, wait for 3 minutes after the power is switched off. | Fuse disconnected | Over Current |
AC part and pattern are short of outdoor PBA | |||
2) | Wiring should be checked | Compressor wire connected clockwise | Wrong assembly |
Reactor wire connected normal | Bad installation or service. | ||
Fan wire connected normal | |||
4way wire connected normal | |||
Sensor wire connected normal | |||
EEV wore connected normal | |||
3) | Supply power and operate the set | Check the power voltage | |
The voltage between Terminal block L-N 200Vac-240Vac | Faulty power cord or wrong power cable wiring | ||
C006 voltage 200Vac-240Vac | Open fuse. L,N,F1,F2 wiring wrong. | ||
CN150 voltage 200Vac-240Vac | Faulty power circuit, load short | ||
PFC050(#26-#27) voltage 200Vac-240Vac 3 minutes later | Open fuse. L,N,F1,F2 wiring wrong. PTC020 open. Faulty RY021/22. Outdoor micom (IC201 error) | ||
CE101 voltage 280Vdc-320Vdc 3 minutes later | Faulty PFC050, wrong connection in reactor wire, load short, the power circuit is faulty, BLDC fan motor error | ||
VoltageCN151 #1-#2 voltage 15Vdc | Load short, switching trans of the power circuit is faulty | ||
VoltageCN151 #1-#2 voltage 12Vdc | Load short, switching trans of the power circuit is faulty | ||
VoltageCN151 #1-#2 voltage 5Vdc | Load short, switching trans of the power circuit is faulty | ||
4) | Check LED lamp display | Normal – Red on, green blink, yellow off | F1, F2 wrong wiring |
Abnormal – All off, check no power | Faulty outdoor PBA | ||
Abnormal; check error mode |
FAQs | Samsung Mini Split Error Codes
The cooling works well. However, it doesn’t cool as well on a hot day. Is something wrong with the split AC?
One reason could be that the outdoor unit is exposed to direct sunlight, and the heat-up air might not be well ventilated. Refrain from cluttering ear the unit and try to set up a sunblind over the outdoor unit.
Why does my AC not cool the room?
Ensure that the AC is not set to ventilation and that the desired temperature is set correctly. Many mistakes set the temperature higher, thinking it would cool the room. But that will make the room warm. So, for cooling, bring the temperature lower.
When I turn on my AC, my eyes burn, and I get a headache. What is wrong with my AC?
Nothing in the air conditioner is designed to give you a headache or irritated eyes. However, nearby smells and pollutants are sucked in, making the mistaken notion that the Air conditioner generates them. Rooting out the source will solve the problem.
The AC smells musty when it is switched on. Help.
This happens when the product is kept properly and dry up the inside of the AC. If you fail to do so, mold will build up, which can also lead to health hazards. Ensure that the windows of the room are open and well-ventilated. Switch on the ventilation function, and it will eliminate the foul smell.
Why won’t my AC start?
Ensure that there is no power failure and that it is plugged in. Check the power panel distribution to see if it is switched off.
Conclusion | Samsung Mini Split Error Codes
It is impossible to survive in some places with the coolness provided by the AC. The Samsung Mini Split Error Codes is the perfect choice to cool yourself in the merciless heat. If you are the lucky few who can afford an AC at your place of residents, keeping it clean and dry and maintaining it well will ensure that the AC sustains for a more extended period. A little bit of know-how and maintenance goes a long way in extending the shelf life.
If you cannot understand the error mentioned above codes or do not know how to use the AC, it makes sense to call the Samsung mini customer care number to have an expert resolve your issues.
