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

I'm inclined to think that a tooth could be broken on a gear or flywheel, if equipped. Of course, you would have to partially disassemble it to check or replace it. It could also be a bad rear roller, or bad spot in the belt, and any worn part associated with the rear roller. Take the unit apart to try and identify the bad component, and hopefully you will spot something obvious.
Here's a site that has some parts:

Good luck, and hope this helps.

Dear Sir:

I hope you are very well, in union with your family.

Thank you by your request, and I will help you inmediately.

Please follow the next step with very carefully:

    • 1
Makesure that the surge protector being used is properly grounded(Very Important) and turned on.Check that the treadmill power cord is properly plugged into the surgeprotector.
    • 2
Checkto see that the key is inserted in the console.
    • 3
Checkthe circuit breaker on the frame near the power cord. If the reset/off circuitbreaker has tripped, wait 5 minutes and then reset the breaker by pressing theswitch in.
4)Check the circuit braker panel house, and reset.
Static Shock Problems:

Many people face a conundrum when using a treadmill. The problem is that a treadmill has you walk or run in a motion that causes you to build up an electrical charge on your body while you are exercising.
The problem if you are swinging your arms, you are totally isolated from any common ground so the charge just builds and builds and many discharges have been measured above 30,000 volts.

You may say, how in a frost-covered hell can I build up 30,000 volts on my body without killing myself? Good question and it has a good
answer...there is very little amperage. It will pop you good when you do ground and sting but it won't hurt you.
The problem is that it can damage the treadmill's electronics if it is not properly designed and we still see poor designs in this respect

If you don't like getting popped or if your treadmill is shutting down or going crazy, there is a fix. You can ground yourself to keep the electricity from building up on your body.

We now have wrist grounding straps that can be reused and attach to the frame of the treadmill without causing any markings and do not require any permanent modification to your treadmill. You can find them in any online catalog by electronic sales by searching for Grounding Strap.

Thank in advance, sincerely. God bless you.

If you need further assistance, please contact us.

SOURCE: Where can I find a Precor 9.21 treadmill motor cover?

Do you know which version of the Precor 9.21 you have? There are a few different versions you can view here. Click on your version to view the parts list and look for "Cover, Motor" or "Motor Cover".

For instance, if you have the 9.21 (AYYZ), the proper motor cover is this part #5019749

However, this part #5005569 is listed as the proper motor cover for the 9.21 (F5), 9.21i (2X), 9.21s (F6), 9.21si (2Y), and a couple others. Make sure you have matched up your exact model number with the motor cover you need so do you not order the wrong part.
