Precor 956 Remanufactured Treadmill - Answered Questions & Fixed issues

Adjusting Tension on a Treadmill Running Belt It is necessary to properly tension a treadmill belt when it is replaced. After time, a belt can stretch and may begin to slip. When this happens, it is necessary to adjust the tension of the running belt to stop it from slipping. Manufacturers of treadmills generally agree on one of three procedures for how to tension a treadmill running belt.

1. Adjust for no slippage of the treadmill walking belt on the front roller (Often referred to as the "Stomp Test")
   1. This procedure works well for a previously installed belt that is now slipping.
   2. Underside of belt should be free of any glazing/wax buildup.
   3. Rollers must also be free of wax buildup.
   4. Be sure belt tracking/centering is correct before proceeding.
   5. The most popular speed for this adjustment is 2mph to 3mph.
   6. Try to slow the belt by applying pressure with your foot against the belt movement while grasping the handrails. If the running belt slow, slips or stops (and the front roller does not) adjust BOTH adjustment bolts 1/4 turn clockwise. Test again and repeat adjustment if necessary.
2. This procedure requires two belt gauges or calipers
   1. This procedure works well when installing a new belt.
   2. This procedure requires you to stretch the belt. Depending on the manufacturer*, this varies between .4 and .6 percent. A dial on the gauge or caliper will indicate the amount of stretch. *Consult the owner/service manual for proper tension.
   3. If you are working on a previously tensioned belt you will need to release the tension before attaching the gauges or calipers.
3. Gauges or Calipers unavailable
   1. Release the tension on the belt.
   2. Using a yard stick or tape measure, place two marks on the left and right edges of the belt and deck 36 inches apart (or 50 inches if you prefer).
   3. Adjust the left and right tensioning bolts until both sides measure 36 3/16 inches (or 50 1/4). This is equal to .5% of stretch.
   4. Test for proper tracking and tension, adjust if necessary.

How to Tension Treadmill Walking Belt that Slips

Precor Error Code 22 Error Code: 22 Manufacturer: Precor Model: All Models Error Description: Error 22, No Motor Pulses at Start Up - Error indicates that the display has sent a command for the drive motor to start, however, the speed sensor has not returned the signal acknowledging that the drive motor has started. Possible Reason:

1. The line of sight between the speed sensor and the speed sensor target is obstructed.
2. Badly worn drive motor brushes.
3. Incorrect gap between the speed sensor and the speed sensor target.
4. Incorrect adjustment of the speed sensor potentiometer (when equipped).
5. Inoperative speed sensor.
6. Faulty lower PCA.
7. Faulty interconnect cable between upper and lower PCA.
8. Faulty upper PCA.

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. Bady worn drive motor brushes cannot make proper contact with the motor commutator, therefore the drive motor will not start when voltage is applied. Inspect and replace drive motor brushes if necessary.
3. 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".
4. 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.
5. An inoperative speed sensor will allow the drive motor to start and run briefly before the error appears. If able to access the speed sensor wiring, measure the DC voltage between the speed sensor leads. Two of the leads will always read about 5 VDC. Two will toggle between 0 and 5 VDC as you slowly turn the speed sensor target. If both measurements are not seen, the speed sensor needs replaced. Some units have the speed sensor mounted on the lower PCA and the lower PCA needs replaced.
6. Determine if the lower PCA is bad by swapping with a known good lower PCA.
7. Determine if the interconnect cable is bad by swapping with a know good cable.
8. Determine if the upper PCA is bad by swapping with a know good upper PCA.

Precor Error Code 22

hi,
Error 45 means the lift moving in wrong direction.The lift control system has detected that the lift is moving in the opposite direction of the issued lift command. There are two possible causes they are,

1- Lift Motor hysteresis.

This error would typically happen when the lift was already in motion (typically downward) when a lift command in the opposite direction (lift up) was issued. Some motors exhibited a very long turn around time and the lift motor would still be moving in the original direction (downward) while the control system was attempting to move the lift in the opposite direction. If the error 45 condition is persistent, replace the lift motor.

2 - Bad lower PCA

This is a very rare condition, if the lift moves in the opposite direction of the issued lift

command, replace the lower PCA

ok

Most treadmills will do this if you are plugging it into a GFI outlet. Check to see what type of outlet you have it plugged into.

Check RPM Feedback: The most common cause for the timer to stop after 7 seconds on a Precor elliptical is NO RPM feedback. Start by checking the connection of the speed sensor to the lower board. If necessary, reset the connection. Also, inspect the magnet located on the user's right crank arm (versions 1 and 2) or the user's left crank arm (version 3). The magnet passes the speed sensor with each revolution of the crank arm. Ensure that the magnet is installed correctly, with its south pole facing the speed sensor. You can verify the magnet polarity using another magnet or a compass. Speed Sensor Spacing: Confirm that the spacing between the speed sensor and the magnet is within the range of 1/8" to 1/4". Adjust if necessary. Battery and Power: If your elliptical has a battery, check its status. A low battery could cause issues. Consider using the optional power adapter kit to ensure consistent power supply. Error Codes and Clearing Logs: Check for any error codes displayed on the console. Clear the error codes and power down the unit. Inspect cable connections to ensure they are fully seated. Power on the unit and monitor the error code log for any reoccurrence. Professional Assistance: If the issue persists, consider reaching out to professional repair services or contacting Precor support for further assistance.

Pour r?soudre ces probl?mes, commencez par v?rifier les connexions ?lectriques. Envisagez d'appeler un technicien qualifi? pour diagnostiquer et r?soudre un probl?me ?lectrique ou ?lectronique si le probl?me persiste.

hello there, check if the lift control system is detected the lift is moving in the opposite direction of the issued lift command. This error would happen when the lift was already in motion (typically downward) when a lift command in the opposite direction (lift upward) was issued.

A slow boot up on a Precor EFX 546 elliptical machine can be caused by several factors, including:

1. Low battery voltage: If the battery voltage is low, the machine may take longer to boot up. This can be due to a weak or old battery, or a problem with the battery charger.
2. Dirty or corroded contacts: Dirt, dust, or corrosion on the battery contacts or other electrical contacts can interfere with the machine's ability to start up quickly.
3. Faulty console or display board: If the console or display board is malfunctioning, it may take longer for the machine to boot up or may not boot up at all.
4. Loose or damaged cables or connections: Loose or damaged cables or connections can prevent the machine from starting up properly and may cause a slow boot up.
5. Outdated software: If the software on the machine is outdated, it may take longer for the machine to boot up or it may not start up at all.

To troubleshoot a slow boot up on a Precor EFX 546, you can try the following steps:

1. Check the battery voltage and replace the battery if necessary.
2. Clean the contacts on the battery and other electrical components.

If none of these steps resolve the issue, you may need to contact a professional technician for further assistance.

Hey Fabian, it's possible that the resistance motor or sensors on your wife's Precor 556i/AXGE may need to be recalibrated. Try powering off the machine, unplugging it for a minute, and then plugging it back in to see if that resets the calibration. If the problem persists, you can try recalibrating the machine manually. There should be instructions in the user manual or online. If that doesn't work, then contacting customer service or a certified technician may be necessary. I hope this helps!

If you have checked the safety switch on your Precor 9.45 treadmill and everything seems to be intact, and the "reset safety switch" message still won't go away, it's possible that the switch itself is faulty or the console is not receiving the signal from the switch. You can try cleaning the switch and the area around it, and also check the wires that connect the switch to the console to make sure they are not damaged. If the switch or wires appear to be damaged, they may need to be replaced. If cleaning and checking the switch and wires doesn't resolve the issue, it's recommended that you contact the manufacturer or a qualified repair technician to further diagnose and fix the problem. They may be able to provide additional troubleshooting steps or suggest other possible solutions.

This is an error code for 1 of 2 things. Something was spilt on the display causing a detected malfunction. Or, you are experiencing a power sag where the unit is plugged in. Try an isolated AC circuit. (Nothing else is ON or plugged in)

Two likely candidates: Belt or tread. Lubricating the tread would be the easiest starting point; but if you're running at 7 or more you've probably already thought of that. If the cover isn't too difficult to remove, you can expose the drive belt and the squeaking volume change would be an indicator that the drive belt is the problem.
