Precor Error Code 62 Vertical Sensor Failure

Jan 27, 2022

Applies to AMT12, all models

Issue symptoms

Error 62 will occur when the vertical stride is not detected. The most likely cause is a faulty, broken, or poor cable connection at the lower PCA(Printed Circuit Assembly). A missing or reversed magnet on the crank arm is also possible, as is a defective sensor. Least likely but possible is a fault on the lower PCA.

Troubleshooting steps:

1. Check to ensure the vertical sensor cable connector is secure on the lower PCA, and that the cable is intact, that it has not been compromised.
2. Verify the magnet is correctly installed in the crank arm. The sensor is polarity-sensitive, and an incorrectly installed magnet will cause this error. To test, remove the magnet from the crank arm, and while in the Stride Sensor test, move the magnet back and forth past the sensor. If the polarity is correct, you will see recorded step counts.
3. If the previous test does not show a count (regardless of polarity), replace the vertical sensor with a known good vertical sensor. Retest.
4. Substitute the lower PCA with a known good lower PCA.
