A centrifugal switch to allow the motor to start up on the start winding and once started it opens to take it out of the start winding. The motor has to have voltage applied to the start winding and the run winding at the same time in order for the motor to start. The capacitor is part of the start circuit. When the motor goes to start, the voltage must be applied to the start winding in order for the motor to start or it will just hum. The moment the motor reaches a certain RPM the centrifugal switch opens up to remove the start voltage to the motor and it will remain running on the run winding. The motor will not start up on run voltage alone. It needs both, the start voltage and run voltage.
I think the problem is that the motor is not getting the start voltage supplied to the motor or the start winding has opened up in the motor.
