The motor may be getting power. Though that dosen't mean it will spin. Motors have brushes inside them that transfer power from the electrical wires from your house, to the many wires inside the motor. These brushes are constantly in contact with the spining shaft in the motor and they will wear out. Sometimes you can replace just the brushes in the motor, but usually it is not worth it. In your case you may want to price out the cost of a new unit. If the brushes are worn out then it is a good chance other parts willbe worn out too. New units can virually pay for themselves in a couple of years. This is probably not what you wanted to hear.
