  1. Verify that the treadmill is plugged directly into the wall, not into an extension cord, surge protector or power strip. CORRECTIVE ACTION: If the treadmill is plugged into an extension cord, surge protector, or power strip, plug the machine directly into the wall.
  2. Verify that the treadmill is on a dedicated 15-amp circuit. CONTACT AN ELECTRICIAN TO VERIFY IF NECESSARY.
