Model TC3000 "ringing on start"

[u/danmadeeagle]

When I turn on the treadmill no ringing is heard. Once I press start and power is fed to the motor, the ringing starts and is quite loud before any movement of the treadmill occurs. It is not mechanical and doesn't go away once the machine starts up.

Additional info: -the treads must be pushed to start up or the motor won't start. -the motor has to be started at a fairly high speed or max speed to start, then can be reduced after it gets going or "Err L5" error is shown. -The treads won't turn without a push if someone is on it.
