Increase speed button on Precor 945i not work

I have a Precor 945i. The increase speed button is not working. How can I fix this? Everything else on the machine is working fine. I contacted Precor & they weren't much help over the phone. They gave me a part number# but they said they did not sell those anymore. Please help.

The problem is that the keyboard is damaged, and although some function buttons is likely that the form of this cut keypad. you should replace it. I leave the link here to a place that sold parts for treadmills.http://www.fitnessrepairparts.com/index.php

9.31 precor error 26 and loud noise


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

If the display stays at 1, then the UP button may be at fault, in which case you would need a new keypad.

The speed will not decrease once the treadmill is started. The speed will increase when the button is selected but will not decrease when selected. Everything else still works except the (speed down)...


Most likely the directional PCA has popped out of its housing. There is a small circuit board underneath the quick start button that works the controls. They are notorious for coming loose. If board is still in the housing then then speed down sector of the board may be bad and it will need to be replaced

This could be caused by either a bad lower electronic board or the brake/generator. I am attaching a link to the service manual for you for further reference. http://www.sportsmith.net/images/product_support/precor/Service%20Manuals/Commercial%20EFX/Service%20Manual,%20C546i%20Self%20Powered%20EFX.pdf
