Check if there's continuity between terminals 1 and 6 on both the old motor (hopefully its not burnt out) and the new motor wiring terminal block.
Terminal 1 (red harness wire) connects to the centrifugal switch in the motor, which connects to the start winding. Terminal 6 (brown harness wire) connects to the other side of the start winding.
At normal the switch is closed, completing the start winding circuit.

Both windings, Start and Run are energized to create sufficient magnetism to overcome the inertia when the motor is idle to start rotating the motor.

When first started, both windings, Start and Run, are energized to create sufficient magnetism to overcome the inertia of the motor when idle, to start rotating the motor.

When the motor has run up to speed, this switch operates to disconnect the start winding allowing the motor to operate on the run winding only. The start winding has only thin wires and you don't want them to burn out.

If the switch is faulty i.e. open circuit, then the start winding is disconnected from the circuit and the motor can't start on the run winding only and you'll hear a humming sound.

If the switch is faulty i.e. open circuit at normal, then the start winding is disconnected from the circuit and the motor can't start on the run winding only and you'll hear a humming sound.
The switch is internal to the motor and there's no separate replacement part.

Hi @roberttanksley
Perhaps the replacement motor is faulty.
Have you still got the old motor?
