Precor Error Code 25 Motor Controller / LPCA Hardware Error

Feb 21, 2022

Applies to TRM800-14/18 treadmills, EFX800-16 ellipticals

Issue symptoms

• On the TRM, this error monitors the functionality of the MC. If the software detects a defect in the MC, the treadmill will stop working and Error 25 will be displayed.
• On the EFX, this error monitors the functionality of the LPCA. The Major processor detects that the Minor processor is not working correctly, is not powering up, or is otherwise out of sync with the Major.

Troubleshooting steps

TRM800-14/18 treadmills

Attempt to clear the error. If it is does not clear, cycle the power three times. If the error persists, replace the MC.

EFX800-16 ellipticals

1. If a continuous occurrence, it is likely a hardware issue or a corrupt program in the Minor processor. Reprogram (future feature) or replace the LPCA.
2. If the problem is intermittent, reprogram (future feature) or replace the LPCA and monitor.
