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

Hey Doug,

Just wondering has this unit ever had the running deck flipped over if not this may be sighs of worn deck or belt or both! What is starting to happen is that at the higher speed the unit is starting to draw more current, so the motrol control board will sense this and will shut down so it won't damage either the motor or board. What starts as an occassional shut down will progressively become more frequent. Simple test is put your hand palm down between the belt and deck,if you feel uneven ridges then the deck needs to be flipped over and when you pull out your hand out and their is a black sooty film on the back of it ,then that seals it this means that the composite material is being shaved off. Most likely the belt will have a smooth glazed feeling in the middle part of it. and well also need replacing.

Press Enter,speed up and speed down simultaneously. Then enter to view error buffer . press quick start/pacer-stop simultaneously to reset error buffer log. Hope this helps

You are refering to Reed switch or Sensor switch or Speed Sensor? please indicate.Some equipment can have the safety switch when you remove the Hood as security measure, for to avoid the machine goes on or Start ON . Please specify.sincerely.

You have strong short circuit in your treadmill machine.Please check the videos carefully using the Dvom instructions attached.

Dear Sir:

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

Please do this with very Carefully!!

The shock is a build upof static electricity on your body called Electrostatic Discharge (ESD).Friction between the walking board and belt can generate static electricity.

If experienced, the shock is not harmful ordangerous.

Thank you in advance, sincerely. God bless you.

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.

Dear Sir:
Hello I hope everything is fine.
I will give some Tips:
Description Errors 00 through Error 04 check upper PCA memory locations, RAM memory locations and EEPROM checksum during the power up test sequence. If a fault is found during the power up test sequence, the appropriate error code will be displayed. Possible Causes 1. These errors messages almost always indicate an upper PCA problem when they are consistently displayed. Failures causing these error messages to be displayed are rare. Possible Remedies 1. If the error message is consistently displayed when the unit is powered up, the upper PCA should be replaced. It is possible to see one of these messages displayed intermittently due to external causes. If the units A.C. input significantly dips during the power up test sequence the test could fail resulting in one of these messages being displayed. Treadmills operating on non-dedicated A.C. circuits may see these messages displayed on an intermittent basis.
In other words, you need recalibration in your equipment, I recomend after you make a test for a RAM MEMORY.so contact your service call. I recomend Strong, INSTALL regulator Voltage is cheap about us$15,00 Radio Shak or another Electronic Place.
Thank you in advance , sincerely. Blessing. If you need additional Help, please do not hesitate to contact me.

You may be able to jerry rig something but it's much safer and always recommended to get a new safety key... saving $20 or less is not worth the risk. Here is one place to purchase a new safety key for the precor 9.21i. I like to recommend ordering two to have a spare and avoid paying for shipping again if you lose another one.

Here is a motor cover for several versions of the Precor 9.21. Not sure if that's what you're looking for or not but maybe that will be useful.. you can click on any of the equipment models listed there to browse a complete parts list.

Check your Amps on the circuit that is being tripped. The treadmill needs 15 Amps to run. If you have a 15 Amp circuit that is running the treadmill and other electronics (or lights), the circuit will trip. You may need to replace the circuit with more Amps.
