I'm having problems with Precor M9.21 Treadmill, the machine will work fine without being stood on (no load) but as soon as you set foot on it will produce a screech type noise and will not rotate. It will simply stop spinning when stepped on.
Apparently there was a new motor fitted just before i bought it. Do you think it may require a new motor?
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

No, I think the deck may not be lube and i want to know when you stand on it does sound like the motor is spinning and the belt is just not moving?? Take off the lid to see. Next you may need a new lower board, this treadmill should be on a 20 amp single circuit. check thopse things first and please rate me great

Thanks.
I have also found that even when the treadmill is turned off and i manually move the belt round is still makes the same screech noise. Its like the gearing is not working right.
