  If your NordicTrack Treadmill power does not turn on, ensure the power cord is plugged into a surge suppressor, and the surge suppressor is plugged into a grounded outlet. Also, make sure the key is fully inserted into the console. Finally, check the reset/off circuit breaker on the treadmill frame near the power cord. If the switch protrudes, wait five minutes, then press the switch to reset it.

  If your NordicTrack Treadmill turns off during use, check the reset/off circuit breaker. Also, ensure the power cord is properly plugged in; if it is, unplug it, wait five minutes, and plug it back in. Another thing to check is the key; remove it and reinsert it fully into the console.

  If the NordicTrack Treadmill walking belt is off-center or slips, remove the key and unplug the power cord. If the belt has shifted left, turn the left rear roller bolt clockwise 1/2 turn. If it shifted right, turn the left rear roller bolt counterclockwise 1/2 turn. Plug in the power cord, insert the key, and run the treadmill for a few minutes. Repeat until centered. If the belt slips, remove the key and unplug the power cord. Turn both rear roller bolts clockwise 1/4 turn.

Why shock does not assist the lowering of the NordicTrack Treadmill frame?
- M
  Matthew CamposAug 19, 2025
  Environmental factors such as cold temperatures can affect the performance of the shock in your NordicTrack Treadmill. To restore shock performance, hold the ends of the frame near the endcaps firmly with both hands, and carefully lower the frame to the floor and then raise it several times. To decrease the possibility of injury, bend your legs and keep your back straight.
