1)
SYMPTOM:
a. The power is on and the console lights up, but the treadmill does not run when keys are pressed.
2)
SOLUTION:
a. Verify whether the console beeps when each key is pressed. If it does not, replace the keypads.
b. Enter Engineering Mode and scroll to ENG 1 (Hardware Test). Press the key “ENTER” first and then
the key ”START”.
- Press the key “SPEED + / -”. If the data on the windows “TIME” and “DISTANCE” is changed, the
console is ok. If the data does not change, replace the PCB.
c. Turn off the power switch and then remove the motor cover. Detach the red & black motor wires from
the MCB, and then u
se a multi-meter to measure the resistance from the drive motor.
- If the resistance is higher than 10
Ω, the drive motor is defective. Replace the drive motor.
- If the resistance is lower than 10
Ω, the drive motor is ok.
d. If the issue remains:
- Check the connection of the speed sensor (encoder disk group) at the MCB.
- Remove the speed sensor from the motor and clean it, then re-test.
- If the speed sensor is clean and has a good connection but still will not operate, replace the speed
sensor.
- Replace the MCB as the last step if machine does still not run.
