when turned on, rpm readout goes to a high speed and jumps around. The rotor is not even turning.

Sounds like you have a problem with either the tach sensor or the control board. The tach sensor is located in the bottom of the drive motor which would have to be removed in order to check it out.

Good morning Don,

Thank you for the response.

How do you remove the motor? From the top or bottom?
