Well, most treadmills emit a small amount of noise, which is to be expected when you have a motor, moving parts, rollers, and a greased belt working together.
But while a few annoying squeaks are to be expected, other noises can be a cause for concern.
The first thing to check for is loose components. You should also check to make sure that the belt and deck are aligned correctly, and that the rollers are turning smoothly.

Treadmill Making Noise? – Possible Causes
Dirty Treadmill Fan
Some treadmills might make noise if the fans are dirty.
The fan is typically used to keep your treadmill motor cool while running. It does this by drawing in the air into the motor component. This air usually has dust particles, pet hair, and carpet fiber which cling to the fan and the motor.
These dust particles have to be removed manually to keep the treadmill running smoothly and stop the treadmill noises.
Getting a good treadmill mat for a carpet will help reduce the chances of dust and carpet fiber entering the treadmill motor.

Exceeding Treadmill Weight Capacity
Treadmills come with recommended weight limits. Exceeding the treadmill weight limit will cause treadmill noise. Exceeding the weight limit will eventually break the treadmill down.
When buying a treadmill, consider your weight and go for a treadmill that will comfortably handle your weight. If you are overweight, go for a heavy duty treadmill.
If you suspect that the motor is making more noise than usual, then it’s time to call a professional to help you figure out what the problem is.
