Causes of Treadmill is Loud When Running

Treadmill Motor Noise

When treadmills are in use, they transmit static electricity. The electricity attracts hair, lint, and dust particles. This causes the treadmill’s motor to accumulate debris.

In such situations, motor brushes stop working and cause noise. To avoid this, you should read the instructions manual provided by the manufacturer and make sure that your motor is cleaned regularly.

If two parts of the drive system scrape against one another, it could make squeaking sounds. Squeaking noises can also be produced by bearings. This is annoying for some people.

These bearings can make grinding noises if they are not in proper alignment. Loose pullies can make screeching sounds. To determine the source of the noise, you should inspect the alignment of the belts and pullies and the motor fan.

The motor fan and bearings may also have been in contact with water or moisture, which could cause them to make unusual noises. If this happens, it is best to seek professional assistance.

If you hear lousy brush sounds, it could be that the motor is heating up too much. This can cause damage to the brushes or even short-circuits in some instances. This can be checked by disengaging the motor belt to hear the motor’s sound.

Belt Noise

You should check that the treadmill belt is correctly adjusted if you suspect the noise you are hearing is due to the treadmill belt noise. Treadmill belts can sometimes be too tight or loose, leading to the machine malfunctioning. A misaligned belt can cause squeaking and screeching noises.

These sounds could be pretty alarming if they are heard suddenly during your workout. The treadmill can also make excessive noise if it has a worn or frayed belt. If your treadmill isn’t placed on a level surface, belts can become loose and cause excessive noise.

Humming Noise

Rollers can cause humming noises. These can usually be repaired at home with no professional assistance. Take off the covers and check for any loose screws or nuts. Grab a screwdriver and tighten any that feel worn. You can also inspect the roller belts and lubricate any problems. Now you’re ready to go!


The bearings are often the source of squeaking noises in treadmills. This is not always true. Other causes of squeaking sounds could include:

  • An unaligned belt is either too tight (or too loose).
  • An uneven surface below the treadmill
  • The belt is not properly lubricated.
  • A higher buildup of dirt and other debris
  • A mixture of muck and oil in the motor.
  • The metal pivot points on the treadmill rub against each other
  • You can fix a creaky treadmill by taking the necessary action.

The treadmill belt can often cause a buzzing sound. This can be quickly resolved by cleaning the underside of your belt. There’s a good chance you will find dust on the belt. To further reduce the noise from your treadmill, make sure you use a high-quality lubricator after cleaning.

Too much belt lubrication can increase friction, cause belt snag, and lead to noise. Low friction is best for motor protection and performance.

Also, the belt lacking oil can lead to being noisy. Take a look at our post How To Lubricate A Treadmill to resolve this problem.

Treadmill Whining Noise

Belt guides are located under the treadmill. These guides prevent the treadmill from making a whining sound if it is pushed too hard. These guides can be bent if necessary to improve the noise situation.
