Fault 09 solving in inverter

[@tunungajilo2214]

Hi thank you for sharing your good work, i have similar inverter Sako Sunon pro 3.5kw with error code 09, i need to know the part number of some components at IGBT driving stage, i can see on video its a similar board so components number as written on the board
Zener diode 1
Zener diode 2
Zener diode 3
Zener diode 4
Zener diode 7
Zener diode 8
Capacitor 138
Capacitor 109

sir can you tell me how to check baising voltage of these igbt that you changed

[@shakeelinvertersolutions5503]

check -5 volt at igbt gate drive

@@shakeelinvertersolutions5503 Dear i am not talking about output igbt where we get 5.6v in off pulse position but that igbt you changed in video derived by 3525
