Tighten Loose Screws and Bolts

One of the most common causes of a noisy treadmill is loose screws and bolts. As you use your treadmill, these components can become loose due to vibration and regular wear and tear. To fix this issue, you will need a screwdriver and a wrench.

Start by turning off your treadmill and unplugging it from the outlet. Then, use your screwdriver to tighten any loose screws on the console, motor cover, and frame. Make sure to also check the bolts that attach the treadmill’s legs to the base. Use your wrench to tighten any loose bolts.

Lubricate the Belt

A lack of lubrication can cause your treadmill to make a squeaking or grinding noise. The belt and deck of your treadmill should be lubricated regularly to prevent friction and extend the life of your equipment. You can purchase a treadmill lubricant at most sporting goods stores.

To lubricate the belt, first, turn off your treadmill and unplug it from the outlet. Then, lift the edge of the belt and apply the lubricant to the deck. Follow the manufacturer’s instructions for how much lubricant to use. After applying the lubricant, run the treadmill at a slow speed for a few minutes to evenly distribute the lubricant.

Check the Motor Brushes

The motor brushes are small, rectangular blocks that transmit electrical current to the motor. Over time, these brushes can wear down, causing a grinding or whining noise. To check the motor brushes, you will need to remove the motor cover.

Start by turning off your treadmill and unplugging it from the outlet. Then, locate the motor cover on the underside of your treadmill. Remove the screws that hold the cover in place and carefully lift the cover off the motor.

Next, locate the motor brushes on either side of the motor. If they appear worn or frayed, they will need to be replaced. You can purchase replacement brushes online or at a sporting goods store. Follow the manufacturer’s instructions for replacing the motor brushes.

Clean the Rollers

The rollers are the cylindrical components that the treadmill belt rotates around. If they become dirty or covered in dust, they can produce a loud, rumbling noise. To clean the rollers, you will need a clean cloth and some rubbing alcohol.

Start by turning off your treadmill and unplugging it from the outlet. Then, use your cloth to wipe down the rollers, removing any dirt or debris. Dip your cloth in rubbing alcohol and use it to clean the rollers more thoroughly. Make sure the rollers are completely dry before using your treadmill again.

Check the Belt Tension

If your treadmill belt is too loose or too tight, it can cause a noise. To check the belt tension, start by turning off your treadmill and unplugging it from the outlet. Then, locate the adjustment bolts at the rear of the treadmill. Use your wrench to loosen or tighten these bolts, depending on the tension of the belt.

Make sure the belt is centered on the deck and that there is an even amount of tension on both sides. Test the tension by trying to lift the edge of the belt. If it lifts more than 2-3 inches, it is too loose. If it does not lift at all, it is too tight.
