Precor Error 45, Lift Moving in Wrong Direction Probable Cause 1. Lift motor hysteresis.
2. Lower PCA is bad.
Corrective Action 1. The error would usually occur when the lift was already in motion (usually downward) when a lift command in the opposite direction (upward) was made. Some lift motors used in production exhibited a very long turnaround time and the lift motor would still be moving in the original commanded direction while the control system was trying to move the lift in the opposite commanded direction. If the error continues to re-occur, replace the lift motor.
2. It is a rare condition, however if the lift moves in the opposite direction commanded, replace the lower PCA.

This squeak is normally caused by a bad bearing in the wheel. In order to provide you with the correct wheel, I will need your serial number. The following link will take you to our Precor EFX 546 page.

Error 44 precor eliptical 546


Precor Error 44, Un-commanded Lift Motion Probable Cause 1. Intermittent or bad connection in the lift position sensor(potentiometer).
2. Lift position sensor (potentiometer) is bad.
3. Lower PCA is bad.
Corrective Action
  1. Bad or intermittent connection of the lift position sensor (potentiometer) is the most common cause of the error 44. Inspect all wiring and connections related to the lift position sensor (potentiometer). Repair or replace wiring connections as necessary.
  2. Monitor the lift position number displayed while operating the lift in diagnostics mode. If the reading makes large changes or is erratic, the lift position sensor (potentiometer) is likely bad. Replace the lift position sensor (potentiometer) or lift motor if the lift position sensor (potentiometer) is internal to the lift motor.
  3. If the lift moves without any command entered either manually or through a program, replace the lower PCA.

My precor efx 544 has stopped recognising that i am using it. does not display strides or calories burned. any ideas?


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.
