    Hi
    If the motor was running when it decided to stop and it hums but does not turn, it is most likely the run capacitor and not the Start Capacitor or a burn out.
    A quick check with the multi meter (on cap setting) on the removed capacitor would verify if it is blown. Make sure the capacitance is the same value but the voltage could be of a higher rating but definitely not less. A voltage higher rated cap seem to make them more reliable. Try not to use chinesium brand as the quality/reliability does vary a lot.
    Remember smoking motors is bad for your health

    If it turns out to be a capacitor an appliance repair shop should be able to get one for you or maybe even a farm supply retailer such s TSC.

    If you open up the cover over the capacitor you should be able to read the value of the capacitor.
    it should have a capacitance with units uF usually between 4 and 25 uF for a run cap and a voltage rating, depending on your local supply, but for the great US of A with 110 volt AC mains assuming single phase motor, should be anywhere over 150volts to around 300volts AC . more than this is unnecessary.

    just double check the size and the connections to make it easy to replace. If you cant find the exact one as long as it is rated the same the wiring can be modified (safely) to suit.
