Gary there should be 2 wires going to the motor.On call for cool check to see if we are getting 120volts between those wires. Most likely we do since it hums.If it does not spin freely the bearings are bad.

You can get a replacement for between 150 and 200 bucks.Give me model on unit and I can help you locate the correct motor.

The 7000 is the series

With fan on high speed we should get 120 between white and black
