  If your Life Fitness Treadmill has no power, first ensure the unit is turned on using the on/off switch. Check that the treadmill is plugged into a power source that meets the necessary electrical requirements. Also, inspect the power connection at the outlet to make sure the line cord is properly seated. If the cord is damaged, replace it. If these steps don't resolve the issue, the display console might be faulty; refer to the 'Display Console' troubleshooting section.
