How to Troubleshoot
1. Insert the safety key properly.
2. Replace the safety key sensor or safety key. If
there is still a problem, replace the console.
Possible
Reasons:
between control board and console, please check to
make sure the wires are connected properly, and the
wires are without any punctures or damage.
If this does not resolve the issue, check the control
board and PCB IC to see if there's any damage.
Replace if necessary.
1. Check if the motor wire is well connected.
Reconnect the wire and restart.
2. Check the motor or the control board for any
damage. Replace if necessary.
Check incline motor sensor wire and AC wire to see
if they are properly connected. Make sure the incline
motor wire does not have any punctures or damage.
Possible Reasons: Excessive current load, the
incoming voltage is too low or too high. The control
board is damaged. A moving part of the treadmill is
stuck, and the motor is unable to function properly.
Try to restart the treadmill. Also, check if there's any
burnt odors around the motor and control board.
Make sure the power and voltage comply with the
standard.
Inspect moving parts to ensure they are operating
correctly. Listen for unfamiliar noises from the motor.
Possible Reasons: The power voltage is less than
normal by 50% or the controller has problems. Make
sure the motor wires are connected. Check the
control board for any damage or burnt odors.
Replace if necessary.
1. Check if the overload button switch is off, if so,
press it to turn it on.
2. Check the wire on the power switch, overload
button, and control board to see if it is connected
properly.
3. Check the console wires and all cables between
the console and control board.
4. Check the transformer and replace if necessary.
