  Christina RileySep 6, 2025
  If your Nautilus Treadmill isn't turning on or the display is not working correctly, start by ensuring the treadmill is plugged into a functioning wall outlet by testing the outlet with a known working device, like a lamp. Check the power cord and its connection to the unit for any damage, and replace if necessary. Inspect the cable wires for crimps or cuts, replacing the cable if you find any damage. Ensure the cable is securely connected and properly oriented, with the small latch on the connector snapped into place. If the console display is cracked or damaged, it should be replaced. If the console only shows a partial display and all connections are secure, replace the console.

What to do if the belt stops moving on my Nautilus T624?
- D
  David RussellAug 27, 2025
  If the belt on your Nautilus Treadmill stops moving during use, first, ensure the Safety Key is properly plugged into the console. The unit may be overloaded, drawing too much current and causing the power to shut off to protect the motor. In this case, refer to the maintenance schedule for belt lubrication, make sure the walking belt tension is correct, and start the unit again.

  The console might be shutting off because the unit isn't getting enough power. Ensure the treadmill is plugged into a functioning wall outlet by testing the outlet with another device, like a lamp. Also, check the power cord and connections for any damage, replacing them if necessary. Ensure all wires in the cable are intact and the cable is securely connected and oriented correctly. If the issue persists, unplug the unit from the electrical outlet for 3 minutes, then reconnect it.

  Heather JohnsonSep 13, 2025
  If your Nautilus Treadmill operates, but Contact HR is not displayed, ensure your hands are centered on the HR sensors and kept still with relatively equal pressure applied to each side. Using a conductive electrode cream (heart rate cream) can help improve contact.

  Linda McclainSep 3, 2025
  Ensure the strap is "POLAR®" compatible and uncoded. The strap should be directly against the skin, and the contact area should be wet. Make sure the transmitter has the curve oriented upward. Check the WIRELESS HR setting in the Edit User Profile option to ensure it is set to ON. Try moving the unit away from potential sources of interference like TVs or microwaves. If the issue persists, replace the strap.
