NO STO Error on StarTrac 4500 Treadmill

Probable Cause

  1. Sticky stop switch
  2. Disconnected stop switch
  3. Faulty stop switch

Corrective Action

  1. Try pushing the emergency stop switch on and off. If the switch appears to stick, replace the stop switch assembly.
  2. Check stop switch connection in the handrail. Reconnect if necessary.
  3. Turn the treadmill power off. Remove the display panel and disconnect the emergency stop switch from the back of the display board. Short the two pins on the display board together using either a jumper or paper clip. Turn the treadmill power on. If the code no longer displays, verify the stop switch connection in the handrail. If the connection is good, replace the stop switch.
