11. TROUBLE SHOOTING GUIDE
Computer not
functioning after
connecting power
1. Please check if the overload protect jump, if it has, please press
it, let it continue operation.
2. Ensure the wires of the power switch, overload protection,
control board and the transformer are connected correctly.
3. Ensure the wire from the computer to the control board is
connected properly. Remove the upright tube and check the
connection between each wire. Ensure each wire is completely
plugged in; if wires are damaged please change the wire.
4. Check the state of the transformer is good, if broken, change it.
1. The wires from computer and bottom control board are not
properly connected, please check each wire. If the wire was
destroyed replace it.
2. Check the state of the transformer is good, if broken, change it.
1. The speed sensor signal was not detected within 5-8 seconds.
Check the sensor plug connection
2. See if the magnetic speed sensor is broken or damaged, re-
connect the plug well or change the sensor.
1. Upon overload, the system will restart to prevent damage. If the
treadmill gets stuck and the motor cannot move it will lead to an
overload. Please locate the cause of this. A possible reason is a
lack of lubricant in a particular component. Then restart the
machine.
2. Check if the motor sounds like its being over worked or for a
burning smell. If so, change motor
3. Check control board. If control board is emitting a burning smell,
change it.
1. Check connection of incline motor wires
2. Check to see if AC wire of incline motor is properly connected,
and if the AC wire of the motor is inserted properly with correct
sign on control board.
3. Check connection line of incline motor to see if it is destroyed,
exchange it or incline motor. Press “learning” button of bottom
control board to relearn upon completion of checks.
1. Ensure power is correct, if not, use correct power to test.
2. Check if the bottom control boards is burnt out, if burnt out
replace it and then reconnect the motor wire.
1. Check and replace controller
1. Check and replace controller
Motor not functioning
after pressing START
button
1. the motor wire is damaged
2. the safety pipe is broken or has fallen off;
3. motor wire is not properly connected
4. IGBT on bottom control board is burnt out. Test the above
reasons and change the relevant part.
