What this symptom means
Powered motor sound or sustained pad motion continues after O is selected and the normal brief coast-down should have ended.
Likely Root Causes
- Rocker did not reach its off contact
- Dust or damage is holding the mechanism
- Electronic control is latched on
- Internal switch or wiring fault
Quick Checks
- After authorized correction, powered motion stops at O and the pad only coasts briefly to rest.
Repair Preview
- Keep the pad clear, set the switch to O, and remove the battery if it is safe.
- Do not touch the pad or reinstall the pack while the off state is uncertain.
- Inspect only the external rocker and housing for jammed debris or impact damage.
- - Do not test again if off control failed
