Precor Error Code ERR EEPROM Problem

Jan 16, 2022

Applies to 9.23, 9.27, TRM211, and TRM200-14 treadmills

Issue symptoms

This error is shown in the console TIME window when the EEPROM is damaged or unable to retrieve or store data. When the Err error occurs, all drive motor and lift motor motion stops and the display is blank except for the error display. When this error occurs consistently, it indicates an upper PCA(Printed Circuit Assembly) problem. Failures causing these error messages to be displayed are rare.

Troubleshooting steps

If the error message is consistently displayed when the unit is powered up, the upper PCA should be replaced. It is possible to see one of these messages displayed intermittently due to external causes. If the input AC(Alternating Current) significantly dips during the power-up test sequence, the test could fail, resulting in one of these messages being displayed. Treadmills operating on non-independent AC circuits may see these messages displayed on an intermittent basis.
