- in this video i explained and demonstrated Split AC Indoor Unit Board Bench Test / How to Test AC indoor unit board. 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
