Normally most home treadmills are 250-300lb user capacity.
Call Precor with your model # and S/N and they can tell you exactly.

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

Hi
not to sound funny but are you sure that you have this tread set in the units (mpg/kph) that you require. i have worked in loads of gyms and its a common problem that people think the belt is running to fast because its set in kph and that thinks its in miles eg 9mph = 14.5kph
you can check and change the units in the club setting menu.
hope this helps :)

SOURCE: I have a Precor c956i

Removethe red "STOP" cover. The cover may pushes against a switch. If theswitch moves too far down and rests against the cover, it will be stuck in alock position causing the error message. To remove the red STOP cover, removethe few screws behind the console. When the front cover is off, turn it overand unscrew the two screws that hold the red stop cover. Then push the coverout through the FRONT. Do not attempt to lift it out by the end with the screwholes. It will not pull out that way. Test the machine before screwing thepanels back again. The message should no longer show STOP KEY. Test the visiblewhite small switch that you uncovered by removing the red flap. The messageshould stop when you press the switch. If theproblem still exists then open the console and check under the magnet holderfrom inside you may see rust ire broken cable there, if you find thisthen you may have to replace it. Hopethis will help you.AV

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

Cuts off and speed is variable and shows err 4


Precor Error E4, Incomplete Initialization Probable Cause Indicates that an incomplete upper PCA to lower PCA initialization occurred. When this error occurs, all lift motor and drive motor motion is ceased and the display will go blank except for the error displayed.
Corrective Action Run the initialization program. Caution: The treadmill's running belt will accelerate to the treadmill's maximum speed (12mph). DO NOT stand on the treadmill's running belt during the procedure.
  1. Set the on/off switch to the OFF position. Wait a minimum of 10 seconds to allow the internal power supply to discharge.
  2. Remove the safety key from the console and set the on/off switch to the ON position.
  3. Press INCLINE UP and SPEED DOWN keys together. While pressing these keys, replace the safety switch on the console. Continue holding the INCLINE UP and SPEED DOWN keys until the display goes blank. INIT will appear in the time window of the display. The EEPROM is now clear and reset. After a second, 1.25 will appear in the distance/calories window, 15.0 (the maximum incline) will appear in the incline window, and 12.0 (the maximum speed) will flash in the speed/pace window.
  4. Press QUICKSTART to begin the speed calibration process. Power bits will appear in the incline window, the target speed will appear in the time window and the actual speed will appear in the speed/pace window. At the beginning of the process, the target speed will be .5mph. The running belt will start. Once the actual speed reaches .5mph, the target speed will then change to 12mph and the running belt will accelerate until it reaches 12mph, then it will stop.
  5. When the running belt stops, the display will return to the user mode and the initialization process is complete.

Precor Treadmill 9.21si Error Code 26, what does it mean


Precor Error Code 26 Error Code: 26 Manufacturer: Precor
Model: All Models
Error Description: Error 26, Motor Pulse Width Incorrect - Observation of the speed sensor signal and verification the signal from the speed sensor is appropriate for the requested speed. If an incorrect or erratic speed sensor signal is detected the error appears. Possible Reason:
  1. The line of sight between the speed sensor and the speed sensor target is obstructed.
  2. Incorrect gap between the speed sensor and the speed sensor target.
  3. Incorrect adjustment of the speed sensor potentiometer (when equipped).
  4. Damaged speed sensor target.
Recommended Action:
  1. Using a static safe vacuum cleaner, carefully vacuum out the drive motor compartment. Be sure to thoroughly clean the area between the speed sensor and the speed sensor target.
  2. Inspect the gap of the speed sensor to the speed sensor target. Proper gap is 3/16" and the speed sensor photo eye should be aimed at the larger portion of the targets wedge shaped section. If unit has a magnetic speed sensor, the gap between the end of the sensor and the flywheel tooth needs to be 3/16".
  3. Locate the speed sensor potentiometer (when equipped) on the lower PCA. Set the speed sensor potentiometer to mid-range. Start the treadmill and increase speed to 6 mph. Carefully adjust the speed sensor potentiometer until the treadmill is operating the smoothest. Increase the speed to full speed and again adjust the speed sensor potentiometer until the treadmill is operating the smoothest. These two adjustments are typically small and are generally only a matter of fine tuning.
  4. Inspect the speed sensor target for any scratches or tears that could cause incorrect readings. Replace the speed sensor target if necessary.

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.

Precor Error LS, Speed Sensor Signal Missing Probable Cause 1. Intermittent or open connection of the speed sensor (reed switch) wiring.
2. Reed switch is defective or has intermittent connection.
3. Drive motor brushes are bad.
4. Lower PCA is bad.
Corrective Action
  1. Inspect the speed sensor (reed switch) wiring for damage or poor connection to the lower PCA. Replace damaged wiring or reset connection as necessary.
  2. Using an ohm meter, test the reed switch while rotating the drive pulley. The reed switch will close when the magnet passes in front of it.
  3. Inspect the drive motor brushes and replace if necessary.
  4. Test unit with a known good lower PCA. Replace lower PCA if nec

Upon powering up my precor treadmill goes straight to the highest incline


hi,
Your treadmills motor controlling circuit have some problem. thats why you cant adjust its speed. its running at its high speed because its motor controlling IGBT become shorted. As these potion of your treadmill is a high voltage point, i will recommend you to consult the manufacturer for support.
ok
