6300/6310 Treadmill Electronics Repair Manual – Troubleshooting
ERR 3
ERR3 indicates that the actual unit speed differs from the speed setting. Unlike older SportsArt treadmills,
though, ERR3 cannot be produced in 6300/6310 models by the user pulling the belt faster than the speed
setting. Resolve an ERR3 issue much like you would an ERR1 with belt movement: check the optic
sensor first. Other possible causes include a bad drive board motor circuit creating irregular power
supply and a poorly connected main program IC.
