Question about Exercise & Fitness
If it is a chirping noise it will be the mylar sheet under your walking belt. You will need it replaced after that kind of damage. If it is an actual grinding noise it will be something else.

The Mylar sheet is probably damaged if it is a whirring sound. The underside of the belt is a fabric and if you think of a continuous piece of corderoy rubbung when pressure is applied, this ma make some sense to you. You can look up "mylar treadmill" on ebay and come up with some suppliers. I got one for $25 + shipping. You will need to know what width it is, usually 17" or 19". You can use a yardstick of a tape measure and pull gently up on the belt and insert the measuring utensil under the belt. It will be narrower than the belt itself, so the measurement is not of the belt, but rather the thin plastic sheet under the belt.
