What to do if my NordicTrack Treadmill power does not turn on?
- S
  Sarah PalmerAug 12, 2025
  If your NordicTrack Treadmill isn't powering on, there are several things to check: * Ensure the power cord is plugged into a surge suppressor, and that the surge suppressor is plugged into a properly grounded outlet, using only a single-outlet surge suppressor that meets all specifications. * Confirm that the safety key is fully inserted into the console. * Check the circuit breaker located on the treadmill near the power cord. If the switch protrudes, wait five minutes, and then press it back in. * Also, verify that the on/off switch located on the treadmill near the power cord is in the 'on' position.

  Margaret BryantAug 17, 2025
  If your NordicTrack Treadmill is shutting off while you're using it, try these steps: 1. Examine the circuit breaker located on the treadmill frame near the power cord. 2. Ensure that the power cord is securely plugged in. 3. Remove and re-insert the safety key fully into the console. 4. Verify that the on/off switch is in the 'on' position. If the treadmill still won't run after these checks, no answer.

  To address a walking belt that's off-center or slipping on your NordicTrack Treadmill: * If the belt is off-center, first remove the key and unplug the power cord. If the belt has shifted left, use an Allen wrench to turn the left rear roller bolt clockwise 1/2 turn. If it has shifted right, turn the bolt counterclockwise 1/2 turn. * If the belt slips, first remove the key and unplug the power cord. Then, using the Allen wrench, turn both rear roller bolts clockwise 1/4 of a turn.

  To recalibrate the incline on your NordicTrack Treadmill: With the key in the console, press one of the Incline buttons. While the incline is changing, remove the key. After a few seconds, re-insert the key. The treadmill will automatically rise to the maximum incline level and then return to the minimum level. This process will recalibrate the incline system.
