What to do if ERROR 30 appears on Precor 5.31 Elliptical Trainer?
- JJoe NolanJul 29, 2025
If ERROR 30 appears on the display of your Precor Elliptical Trainer, the cause might be an incorrect RJ45 cable connection. To resolve this, remove the cable and re-insert it into the other receptacle on the back of the display console. Ensure you use the correct receptacle, which has the tab opening at its base.
