    If it is a 3 phase motor, it has to have a motor controller/contactor.  Usually with overloads. If you have voltage to all 3 poles of the top of the contactor phase to phase, then your input power is ok.   Next see if the contactor is closing. If not it will take a bit of tracing out why.  I don’t know what you have for control, buttons or switch or interlock with your hood system or a machine.

     

    I don’t have any idea of what you know or what meters and test equipment you have. If you aren’t comfortable with electricity, hire a electrician
