How do I fix my Endurance Treadmill TF3i Err7 problem? I stopped during operation.

Unplug unit remove motor shroud check connections on lower board (incline board). I believe their is a 3 amp fuse in circuit check with multi meter to see if open replace fuse power up unit and if it blows the fuse then replace incline motor and if not, then use engine mode press stop then Incline + or - to force incline up to max incline then bring it down to 0 then turn off power then wait 10 seconds then hit power on then if error does not appear then hit start and resume using unit. If the procedure above does not activate unit then replace board.
