What to do if my True Treadmill shows Fault SC05: Motor Over Speed?
- JJean ReedAug 27, 2025
A 'Motor Over Speed' fault on your True Treadmill can be triggered by a few things. High friction between the belt and deck may be the cause, so lubricating the treadbelt is a good first step. Make sure that the AC line voltage is correct. If the speed sensor is dirty or misaligned, it is best to contact your dealer or TRUE service.
