5.7 Troubleshooting-Noise Issues
SOLUTION:
a. Thumping noise twice per rotation on new machine.
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. High pitched “bell-like” sound from under the motor cover.
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 bearings are rubbing. Replace the motor if needed.
- Check the front and rear rollers, replace if needed.
c. Rubbing / grinding noise.
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. Banging or clunking sound/slapping / squeaking sound with each footstep. 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.
- This sound is from the running deck / belt.
- Remove the side rails and tighten the deck bolts and elastomers.
- Check the deck shocks for disintegration or crumbling. Replace if needed.
e. Rubbing sound underneath the treadmill. This sound is likely due to the air shock.
- Lubricate or replace the air shock as needed.
f. Squeaking / grinding noise when using elevation. This sound is likely from the incline motor.
- Check that the incline motor and incline rack connection points to the main frame are tight.
Replace Teflon washers on the frame as needed.
- Lubricate the incline motor worm screw and connection points with grease.
- Replace the incline motor.
