NordicTrack 1750 - NTL14221.2 - new controller

Hello Kevin and group,
I recently replaced the controller on my treadmill. I can
1)Start and Stop
2) Incline/decline
3)Control the speed
The issue is when i step on the belt, it stops moving while the motor runs. The controller blinks red (as desired) during this time. the deck is okay, belt is well lubricated with tension being not too high or low and as far as i know all the connections to the controller are snug. One more thing i have tried is to play with the torque potentiometer on the controller with same outcome. please advise ?
Best Regards,


  • adjust and or replace the belts. Both the drive belt and walking belt.
