That is why I'm wondering why you think it is the motor rather than the resistor.

To put it simply, the only thing that will cause the original resistor to go is a motor that is drawing too much current. The increased power consumption is not necessarily converted to noise until it is too late to save the resistor.

As the bushings gum up and keep the motor from starting easily, the resistor sees locked rotor current for increasingly longer times until it overheats (with no cooling) and opens. In any switch position other than off or 4, the motor and resistor have their fates inextricably entwined, and it is always the motor's fault.
