10 year old, well maintained f63 sole treadmill. I tried to lubricate belt, adjust tension, and adjust speed sensor since this is often recommended for troubleshooting.

Thoughts on cause? If you had to try replacing something, what would you try? These components (motor, board) are not cheap so trial and error will exceed cost of a new treadmill after a few wrong guesses :(.

In video, I can see a green LED on the board light up when I step on the belt. After a while, it seems to fault, shutting down the motor. The LS1 fault display shows up about 3 seconds later when it notices it is not moving.

Thanks!
