How to fix a Horizon Fitness T900 Treadmill when the console doesn't light up?
- CColleen LongJul 30, 2025
If the console of your Horizon Fitness Treadmill doesn't light up or the belt doesn't move, first, ensure the outlet is working and the breaker hasn't tripped. It should be on a dedicated 20-amp circuit, not a GFCI outlet, and not plugged into a power strip, surge protector, or extension cord. Also, check that all connections, especially the console cable, are secure by unplugging and reconnecting it. Make sure the console cable isn't pinched or damaged. Finally, turn the power off, unplug, wait 60 seconds, remove the motor cover, and check for loose wires on the lower board. Ensure the power cord isn't damaged and is properly plugged in, and the power switch is ON.
