      If your NordicTrack Treadmill's power turns off during use, check the circuit breaker located near the power cord and reset it if it has tripped by waiting five minutes, then pressing the switch back in. Also, ensure the power cord is properly plugged in; if it is, unplug it, wait five minutes, and plug it back in. Remove and reinsert the key fully into the console. Finally, verify that the on/off switch is in the 'on' position.

      steven34Aug 18, 2025
      To troubleshoot a NordicTrack Treadmill that won't turn on, ensure the power cord is connected to a surge suppressor, which is then plugged into a grounded outlet. The treadmill isn't compatible with GFCI outlets. Also, make sure the key is fully inserted into the console. Check the circuit breaker near the power cord and reset it if tripped by waiting five minutes and then pressing the switch back in. Finally, verify that the on/off switch is in the 'on' position.

      If the walking belt on your NordicTrack Treadmill is off-center: * 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 has shifted right, turn the left rear roller bolt counterclockwise 1/2 turn. * Plug in the power cord, insert the key, and run the treadmill briefly. Repeat until centered. If the walking belt slips when walked on: * Remove the key and unplug the power cord. * Turn both rear roller bolts clockwise 1/4 turn. * Plug in the power cord, insert the key, and carefully walk on the treadmill. Repeat until properly tightened. You should be able to lift each side of the belt 3 to 4 inches off the platform when correctly tightened. Be careful to keep the walking belt centered.

      To recalibrate the incline on your NordicTrack Treadmill, insert the key into the console, and press an incline button. While the incline is changing, remove the key, wait a few seconds, and then re-insert it. The treadmill will rise to the maximum incline and then return to the minimum, recalibrating the incline.

    Why does the NordicTrack NTL99020 walking belt slow down when I walk on it?
    • J
      jordan35Sep 4, 2025
      If the walking belt on your NordicTrack Treadmill slows down when you walk on it: * Ensure you are using a single-outlet surge suppressor. * If the belt is overtightened, remove the key and unplug the power cord. Use an allen wrench to turn both rear roller adjustment bolts counterclockwise 1/4 of a turn. When the belt is properly tightened, you should be able to lift each side 3 to 4 inches off the platform. Keep the belt centered. Plug in the power cord, insert the key, and run the treadmill for a few minutes.
