An incline motor runs (you can hear it operating) but the treadmill deck does not rise. The most likely cause is:
- AA motor control board input voltage fault
- BA stripped gear in the actuator drive mechanism or a failed linear actuator
- CInsufficient lubrication on the running belt
- DIncorrect incline setting in the console configuration menu
Correct Answer
A stripped gear in the actuator drive mechanism or a failed linear actuator
Explanation
If the motor runs but produces no movement, the mechanical link between motor and frame is broken — typically a stripped worm gear, sheared coupling, or failed actuator rod.
