Since it sounds like you're running in conventional mode, how about a sure-fire fix?

Get a few of the KBF404 4A Bridge Rectifier parts from Digikey.

Wire them like this. For each bridge component, you drop the voltage applied to the motor about 1.5 volts. Normally two or three of these in series with the motor will give enough additional voltage to the smoke resistor to solve the problem.
