Precor Error Code LS

Probable Cause

  1. Intermittent or open connection of the speed sensor (reed switch) wiring.
  2. Reed switch is defective or has an intermittent connection.
  3. Drive motor brushes are bad.
  4. Lower PCA is bad.

Corrective Action

  1. Inspect the speed sensor (reed switch) wiring for damage or poor connection to the lower PCA. Replace damaged wiring or reset connection as necessary.
  2. Using an ohmmeter, test the reed switch while rotating the drive pulley. The reed switch will close when the magnet passes in front of it.
