My treadmill is making a screeching sound when I step on it. It makes no sound when running without me on it. what could the problem be?

It is probably the join on the belt itself as it passes the over the roller. It could be a sign that the belt is breaking.

Sounds like your belt is slipping. Check your manual, it'll probably tell you how to service it.

have you lubricated the belt ?

loose belt

This definitely sounds like the drive motor. One way to check is to remove the drive belt and run the motor without the walk belt connected. Obviously if you still have the noise it will be a motor issue. If not then it will be one of the 2 rollers. Good Luck! Tim

This probably did not happened suddenly right? the problem is not the motor however you can easily check the blue capacitor for peace of mind. with the power disconnected, disconnect one side off the capacitor from the top. with a ohm meter put the 2 probes on the cap,you will ear a temporary beep sound from your meter, then reverse your probes on the capacitor and again a temporary sound that mean your capacitor is good and your motor will run OK.

Your problem is more then likely your run belt and bed assembly. When new, these are coated with a wax of some kind for slipping, has you use the machine wax wears off, and so is the belt. You can see a black rubber dust at the rear of the machine. And so resistance increase when pressure is applied on the running belt.

Just behind the on/off switch where the power cord goes in, there is a auto reset 15 amp breaker that trips when too must resistance against the motor increase the amperage over 15amps. At 7 min/m on your speed setting and if the belt is adjusted correctly with nobody on, the motor pull about 6amps, with someone like me 180lbs, the motor pulls an avg of 10amps with a new belt.

If you have a clamp amp meter you can test it yourself.

2 parts you will need to fix this; 50985-101 (bed assembly) and 36355-101 (run belt 17 X 110) This is real easy to install.

make sure these parts are for your machine model # as they did increased the width of their belt over the years

Since 1998 I had to replace these parts 2 times with an average of 3 people using the treadmill every day. This is a good machine and if everything else is good it's worth it. I paid $300 for these parts, i'm sure if you shoppe a little you can do better.

Have a good one

The 1,5 year new dryer makes a terrible screaching noise when it has a load of clothes in it. It still dries fine, no problem with the heating element. No noise without clothes, only when it has a load.
