Answers:    Yep, fireguy's correct. It is most promising a burned out motor winding. You can undamagingly continue to use it on illustrious speed or go shopping for a hot motor.
the most probable answer is that there is a loose nouns on the motor or part of it burned out. a two stage motor will hold electrical leads for both lofty and low. frequently one will work but not the other. check both leads next to a electrical tester. if one is burned out an replacement motor is only roughly speaking 70 bucks.
