TROUBLESHOOTING
NO POWER TO THE CONSOLE
1) SYMPTOM:
a. The power switch is in the on position, but the console will not turn on.
2) SOLUTION:
a. Check to see if the power switch is lit. If it is not, try a different outlet.
If the power switch still does not light up with a known good outlet, replace the power switch.
b. Check to see if the MCB has power. There is a red power LED on the MCB that should be lit.
c. If the MCB does not have power, check the connection of the power wiring from the power receptacle to the MCB.
Use a multi-meter to measure AC1 & AC2, AC voltage shall be same as local’s standard voltage (110V-240V)
If AC voltage value is standard, replace the MCB as it shall be defective.
d. If the MCB does have power, check the connection of the console cable wire at the MCB and UCB.
Remove the console cable from MCB, and use a multi-meter to measure the DC voltage between the “GND pin” (Pin4&5) and the ” + 15V Pin” (Pin7 & 8). DC output is normally around DC 15V. If no output, replace the MCB.
If output is around DC 15V, check the console cable. If it is defective, replace the console cable.
If the console cable connections are all good, replace the PCB.

THE POWER IS
ON, BUT MACHINE HAS NO RESPONSE
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. Check if the console beeps when all keys are pressed. If no, replace the keypads.
b. Enter Engineering Mode. and scroll to ENG 1 (Hardware Test).Press the key “ENTER” first and then the key ”START”.
When press the key “SPEED + / -“, if the data on windows “TIME” & “DISTANCE” is changed, the console is ok. If not, replace the PCB.
c. Turn off the power switch, and open the motor upper cover. Remove the red & black wires of motor from the MCB, and use a multi-meter to measure the resistance of drive motor.
If the resistance is bigger than 10 , the drive motor is defective. Replace the drive motor.
If the resistance is lower than 10 , the drive motor is ok. Then,
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 after to take above actions.

INCLINE MOTOR
ISSUES
1) SYMPTOM:
a. The incline motor does not lift up or down.
2) SOLUTION:
a. Enter Engineering Mode ,and scroll to ENG 1 (Hardware Test). Press the key “ENTER” first and then the key ”START”
a. The incline motor does not lift up or down.
2) SOLUTION:

Press the key
“INCLINE UP/DOWN”.
If can hear beeps from two relays at the MCB, the MCB is ok. Then check the connection of the elevation motor at the MCB first, try to unplug and re-plug these two pins. If cannot resolve the issue, replace the elevation motor.

NOISE ISSUES
1) SYMPTOM:
a. Thumping noise twice per rotation on new machine.
b. Rubbing / grinding noise.
c. High pitched “bell-like” sound from under the motor cover.
d. Banging or clunking sound.
e. Slapping / thunking / squeaking sound with each footstep.
f. Rubbing sound underneath the treadmill.
g. Squeaking noise when raising / lowering the deck into storage positions.
h. Squeaking / grinding noise when using elevation.
2) SOLUTION:
a. This noise is from the roller or running belt.
If this is a new unit, some noise is normal as the running belt forms around the rollers.
Check that the belt is centered and tensioned correctly.
Remove and clean the rollers if needed.
Replace the rollers or running belt as needed.
b. This sound is likely a moving component.
Remove the motor cover and check the drive belt for alignment and make sure it is not slipping or is frayed / cut in any way. Replace the drive belt if needed.
Make sure the optic disk on the motor is not rubbing the speed sensor.
Turn the motor by hand to see if motor brushes or bearings are rubbing. Replace the motor
if needed.
Check the front and rear rollers, replace if needed.
c. This sound is likely caused by the optic disk.
Check that the optic disk is tight on the motor and not rubbing the speed sensor.
d. The sound is likely due to the unit not being level.
Check that all levelers are touching the ground.
Move the treadmill to another flat surface
e. This sound is from the running deck / belt.
Check that the running deck is tightly attached to the frame.
Check the deck shocks for detioration or crumbling. Replace if needed.
Check to see if the air shock is making this noise, lubricate or replace if needed.
f. This sound is likely due to the air shock.
Lubricate or replace the air shock as needed.
g. This sound is likely from the incline motor.
Check that the incline motor connection points include Teflon washers.
Lubricate the incline motor worm screw and connection points with grease.
Replace the incline motor.
