Treadmill will not start
Possible causes:
1. Max SPD button has not been adjusted properly.
2. Console cable or PCB is damaged.
3. MCB is damaged.
4. Transformer (7-pin) is damaged.
5. Motor is damaged.
Solution
Open motor cover, verify wire connection M+ and M- (motor wire) and transformer (7-pin) on the MCB then plug in the power cord and turn on the power switch. Then press “POWER, START, FAST“ buttons.
1. Adjust the “SPD” until the motor start to run.
2. Verify the LED indicator of LED4 is lit. If that LED4 is not lit, replace console cable or PCB.
3. Replace MCB
4. Replace transformer (7-pin).
5. Replace Motor.
Treadmill will stop by itself
Possible cause:
1. Poor interconnection.
2. ESD.
3. PCB (especially true when stop in the scanning mode).
4. Low magnetism of the safety switch.
5. Bad motor
Solution
1. Verify the interconnection between wires.
2. Advise JMI.
3. Replace the PCB.
4. Replace the safety switch.
5. Replace the motor
Running speed is not stable
Possible causes:
1. AC power voltage is too low.
2. Tension of drive belt or running belt is too loose. Poor adjustment of MCB.
3. MCB is damaged.
4. Motor is damaged.
5. Poor lubrication between the deck and the belt
Solution
1.Check the power voltage by using voltage-meter to see if it is within 120V+-15% or 230V+-15%.
If the power voltage isn't within the range, look for a qualified electrician for help.
2.Open the motor cover, if the belt has stretched and is slipping across the rollers when running.
Adjust the belt tension.
3.Remove the motor cover and run the machine at low speed, then adjust the IR COMP and MAX SPD on MCB.
If it hasn't been improved, replace new MCB.
4.Replace new motor.
5.Relubrication.
Treadmill will incline up or down by itself
Passable causes:
1. The console cable is damaged.
2. MCB is damaged.
3. PCB is damaged.
4. Incline motor is damaged
Solution
1. Use a new console cable to connect PCB to MCB. Then turn power on, press "UP" and "DOWN" key to see if the incline motor will be OK. (If the treadmill still works by itself go to next step)
2. MCB is damaged.
2.1 Check if relay parts (REL1, REL2) failed with a multimeter to measure the resistance of REL1 and REL2.
Replace REL1 & REL2 if either failed.
2.2 Replace MCB.
3. OR: Replace PCB.
OR: Replace incline motor.
Noises
generated under motor cover
Possible
causes:
1. The running belt tension is adjusted too tight.
2. The bearing of front roller is not installed correctly.
3. Dirty grooves of drive belt.
4. The motor is damaged.
Solution
1. Adjust the belt tension so that the belt does not start slipping and then check if the noise has disappeared. Let the treadmill run, without using it, for at least 5 days because sometimes the bearing will settle and become quiet then check if the noise has disappeared.
2.Replace the front roller with a new one to see if the noise disappear.
3.Remove drive-belt and check the grooves in belt for dirt or dust and clean if necessary. Clean also the motor pulley and the roller pulley groove and check if the noise has disappeared.
4.The motor bearing is damaged.
Replace the motor.
