SOURCE: Precor EFX 546 elliptcal shuts off

Your problem is most likely due to the magnetic sensor on the right side of the unit under the plastic housing.
The right pedal arm, has a magnet emeded in the on the inboard side of the arm. When the arm comes around and passes this sensor at the bottom of the unit, a pulse is generated and sent to the computer.
The mangetic sensor on the frame of the unit, may need to be adjusted to a closer proximity with the pedal arm magnet. Assure the arm does not strike the magnetic sensor however.
It's also possible the sensor has come loose and fallen into the base of the unit.

SOURCE: new battery

A lower capacity battery (12v 8Ah) can/should preferrably be replaced by a better capacity (12v 12Ah), and usually more expensive, quality battery of the same voltage with higher amperage rating: it will in general take longer to charge but will also last longer in usage.
Please make sure that you fully charge and discharge your new battery pack a few times to 'condition' it.

Hope it helps and have fun!

It may be either the front shroud is installed incorrectly or broken, or the corkscrew for the incline motor is bent. If it is bent, it would need to be replaced.

How to repair a 546 efx precor

Assuming the buttons are working, the numbers change on the display, and the incline works, it may be the lower circuit board or the generator. If it is a very old unit, it may be the electromagnet or the data cable that connects the two circuit boards.

Error 45 on Precor EFX 546 Elliptical

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.
