Precor Equipment Troubleshooting and Technical Support

  • Ellipticals

    • I just replaced the crank arm on my Precor Elliptical EFX 546 and now the display doesn't work, what is wrong?

      Often when a new crank arm has been installed, the magnet for the speed sensor is discarded with the old crank arm.  You will need to remove the magnet from the old crank arm (located behind the pedal arm shaft of the crank arm, see reference points A and B) and install onto the new crank arm. The magnet is found on the user's right crank arm for Versions 1 and 2 and on the user's left crank arm for version 3.

      Without the magnet, the speed sensor is not able to detect that the unit is in motion.  The display may prompt the user to "keep pedaling" or may even shut off after a few seconds (commonly 7 seconds).   You may even experience that the cross ramp does not repsond and there are no rpms being shown on the display.

      Be advised the speed sensor is pole sensitive to the magnet. If the magnet is not installed with the south pole facing the speed sensor, the unit is unable to pick up motion of the crank arm. You will need to reinstall the magnet with the south pole facing the sensor. You should have spacing of 1/8" - 1/4" between the speed sensor and magnet. 

    • My Precor Elliptical EFX 546 Timer Stops After 7 Seconds, what is wrong?

      The most common cause for the Timer to Stop After 7 Seconds on a Precor Elliptical is NO RPM Feedback. 

      Knowing the status of the unit from its last use as well as the last service or part replacement is a great place to start.

      Check the connection of the speed sensor to the lower board.  Reset connection if necessary.

      Check the magnet.  The magnet is located on the user's right crank arm on versions 1 and 2 and the user's left on version 3.  The magnet passes the speed sensor with each revolution of the crank arm.  The magnet should be installed so that its south pole is facing the speed sensor.  You can check the magnet polarity with another magnet that has marked poles or a compass.  The north pole of the marked magnet or the south facing needle should be attracted to the magnet.  Correct magnet installtion if necessary.

      You may also check the spacing of the speed sensor to the magnet.  The spacing should be 1/8" to 1/4".  Adjust if necessary.
