My Z axis motor is moving up but not down. How do I troubleshoot?

Lubricate rods, turn off printer - does it still stay?
If it moves down when powered off, but not when powered on, I would guess either a driver is partially dead or the controller.
If it does not move at all, I would say the bearing might be blocked somehow.
