149 Split AC Indoor Unit Board Bench Test / How to Test AC indoor unit board

in this video i explained and demonstrated Split Split AC Indoor Unit Board Bench Test / How to Test AC indoor unit board Troubleshooting in urdu hindi. i used 10K ohm potentiometers t simulate the pipe temperature sensor and room air temperature sensor. so simulated signal is applied to microcontroller to generate command signals. and in this way we can different modes of operation and circuit behavior it is KFR-70GW series board used in Chigo Split AC, Feng Xia Series, Mitubishi Split AC, and GD Midea Refrigerant Equipment indoor unit. i demonstrated how the circuit works and how to troubleshoot, if 1. indoor fan not working 2. swing motor does not move 3. compressor does not start 4. outdoor unit cooling fan does not spin 5. heat cool valve not changing to heat or cool 6. indoor unit displays error code 7. how to test indoor unit room temperature sensor 8. how to test indoor unit pipe temperature sensor 9. how to test power supply circuit 10. how the microcontroller controls the function of the split ac unit how to repair split ac,how to repair split ac indoor unit,indoor unit board repair,test,function explained,troubleshooting,KR70GW,indoor unit circuit repair,indoor unit,indoor unit fan not working,indoor unit ice problem,indoor unit error,indoor unit error codes,e3 error,e3 error code air conditioner,e4 error code air conditioner,e6 error,e6 error in ac,how repair indoor unit circuit,how to test indoor unit kit,how to,circuit board,ac pcb service center
