I have a Precor 9.3 Treadmill. I"m having problems mounting the console board. When I mount the bolt in the front of the console board, that"s fine, but when I go to mount the 2 bolts in the back , they won"t reach to mount.The only way for them to reach is to lay the console down a bit,but then the console board is down more rather than sitting up. Has anyone had this problem.

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

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.

The incline on our Precor c964i is stuck in a high position (approx. 10% incline). Other than being on a high incline, the treadmill seems to be working fine.


Hi There,

Precor uses a pair of Triacs to drive the lift up and down. These triacs live on the lower board but are driven by the upper console commands via a serial link between the upper and lower. Most precor lift issues we see are related to the lower board but with Precor it could be an upper board or the CPU Chip that resides on the lower board or a failed Triac. Good Luck

Drive Belt Installation for Treadmills

The drive belt is used by the motor to drive the treadmill walking belt via the front roller pulley. A drive pulley is mounted on the roller and the roller has knurling or a sleeve to help it drive the walking belt. The treadmill console detects the current speed of the treadmill by monitoring the movement of a magnet mounted on the front roller pulley with a reed switch or by using an optic switch which monitors an optic disk mounted either on the front roller or on the motor shaft. If the sleeve moves to the side, you will not be able to keep the belt centered and many optic disks can be warped if pushed to the side by the sleeve if it moves, but we do have replacement sleeve kits if needed.


Steps to Replace Drive Belt-

1) Remove the safety key and unplug the treadmill from the wall outlet.

2) Remove the screws securing the motor hood and gently remove the motor hood.

3) Using an Allen wrench provided with the treadmill, loosen the two rear roller adjustment bolts until the rear roller comes into contact with the walking board. Turn the bolts and equal number of turns on each side and keep a count of how many turns you made so you will know how to properly re-tension the walking belt.

4) Remove the drive belt from the motor pulley. Place a screwdriver between the pulley and the belt and turn the pulley by hand. Use the screwdriver to guide the belt over the edge of the pulley. Be careful with the screwdriver to prevent damage to the pulley.

6) Mark the position of the front roller axle on the front roller bracket above the front roller adjustment bolt using a Sharpie marker so you will know where to put the bolt back into position. Remove the front roller adjustment bolt if your treadmill's front roller has a pitch adjustment bolt. If your treadmill does not have exposed roller bolts you will need additional instructions. Please see the troubleshooting section on our website for further help.

7) Gently slide the front roller from out of its mounting position on the frame. Do NOT remove the roller from the walking belt.

8) Slip the old drive belt off the roller and loop the new drive belt onto the front roller pulley.

9) Replace the roller back into its slot on the pulley side and re-tension the front roller pitch bolt to its proper place using the Sharpie mark as a guide.

10) Using the screwdriver, loop the drive belt over the motor pulley. Many Icon units originally had the drive belt misaligned by design (if you can believe it). This was to use the side load of the drive belt in order to keep tension lower. It does lower amp draw for the machine and replacing a side load drive belt occasionally is much cheaper than replacing a motor and/or controller so if your original drive belt was off-centered, install the new belt in the same manner.

11) Re-tension the walking belt.

12) Plug in the machine and check the drive belt for slipping. You can use some automotive fan belt dressing on the grooved or contact side of the belt to help it with grip on the pulleys and it will treat the belt as well. We prefer using belt dressing rather than over-tensioning the belt for the aforementioned amp reasons as well as additional stress placed on the drive system parts.

13) Replace the motor cover and test.

14) Make sure the walking belt is not slipping and is properly aligned and your treadmill is ready to use.

SPEED ERROR ON PRECOR 927 TREADMILL


I had the speed error on my precor 9.23. When I opened it up I found that there are two little round magnets on the belt pulley with a sensor mounted nearby. This must be how the computer know the speed of the treadmill. I noticed that there were several little metal shavings stuck to the magnets. Not sure where they came from, hopefully not another problem. However, I removed the metal shavings from the magnets and everything worked fine again. If anyone else has the speed error it might be worth a look to see if its the same problem.

C2255 treadmill - everything works but the console light no longer comes on - nothing in manual to show what the problem could be.


If the console takesbatteries, replace them. If this does not work or your console does not requirebatteries, check the reed switch or optic sensor. Reed Switch:Unplug the treadmill and remove the motor hood cover. The reed switch is mountedon the frame next to the front roller pulley. There is a magnet glued into thefront roller pulley. When adjusting the reed switch, make sure it is pointingdirectly at the magnet. Move the tip of the reed switch within 1/8" of themagnet. Also, check to see that the wire is not damaged, and is connected tothe console.
See the diagram adjust for 1/8"

After that: Do the next: 1) Tight the flexible cable from keypanel vs Display board.2) Tight the connector from Display Board vs Lower Board( Main Controller Board). See the block diagram that I did how the main controller board has aprox 90% of function from the any treadmill

Optic Sensor: Unplug the treadmill and remove the motor hood cover. The optic disk and sensor are located either at the end of the motor or the right hand side of the front roller. The optic disk spins between two sensors on the optic switch. The disk must spin freely without touching either sensor. The sensors can be moved by loosening the adjustment bolt holding the switch to its bracket. The switch can then be slid. Center the disk.

Remember :The controller for console or display have circuit for magnetic swithc.

My Proform 695 LT runs fine when Iam not on it but when I get on the machine it starts pausing in between running or even a slow walk


Unplug unit remove motor shroud then plug unit back in , press start and begin walking on the belt normally and try to stall the belt to make it slip ( planting foot to stop the belt).
Be careful during this test. If the problem is in the drive belt, either the drive belt will stop when stalled or the front roller will stop when stalled. Here is the procedure for adjusting the drive belt.
Find the motor mounts. Many motors in Icon treadmills have a main pivot joint in which a bolt runs the full length of the motor mount. This bolt will require loosening to provide maximum adjustability. Some models have a single jack bolt and others have an auto tensioner. Single jack bolts are the easiest to adjust.
Find the set bolt(s) on the motor. This is typically run through only one side of the motor mount or may be on both sides but it does not run the full length of the mounting. Loosen this bolt(s) but do not remove. Jack bolt models will have flat mounts and may contain up to four bolts.
Look for a bolt that will tension the motor. If it has this bolt, it typically runs in the same direction parallel with the drive and walking belts. If your treadmill is not equipped with this bolt, skip to Step 4. If your treadmill is equipped with this bolt (very few are) the repair will only require one person. Using 2 7/16" wrenches, make a few turns to this bolt, tighten the bolts and test your treadmill for slipping. If belt continues to slip, and if their is too much tension ( you should be able comfortably twist the drive belt 90 degrees ) then replace drive belt. If the motor, drive belt, and front roller continue to turn when the walking belt is stalled, the problem is with the walking belt slipping on the front roller, here the procedure adjusting the walking belt.
If the walking belt slips when walked on, first remove the key and UNPLUG THE POWER CORD. Using the allen wrench, turn both rear roller bolts clockwise, 1/4 of a turn.When the walking belt is correctly tightened, you should be able to lift each side of the walking belt 3 to 4 inches off the walking platform. Be careful to keep the walking belt centered. Plug in the power cord, insert the key and carefully walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened
If the drive belt continues to turn but the front roller stalls, you may have a broken front roller pulley. If this is the problem, you will notice it because the plastic will usually make a loud squealing sound on the metal front roller. The front roller assembly will need to be replaced and the drive belt must be replaced also. We suggest replacing the drive belt as well because it is a low cost item and will most likely, have suffered unusual wear from the problem. Another possibility is that the drive belt has worn down. In some cases, belt dressing may help correct the problem. If not, the drive belt must be replaced.
