Although replacing the motor shouldn't affect the console, I would first check the function of the motor by connecting 12-18v DC to it to make sure that it runs at a constant speed with a constant voltage. If it does, then follow that back to the motor controller board and see if it is sending out voltages to the motor and that they vary when you vary the controls. It may be a bad motor controller board and this will help you find out, especially if it is the same problem that led you to do this repair.
