  If the incline function on your Sunny Health & Fitness Treadmill is not working, it could be due to the following reasons: 1. The incline motor VR wire is not connected well. Re-connect it. 2. The incline motor AC wire is not connected correctly. Ensure the AC wire on the incline motor matches the mark on the control board. 3. The connect wire on the motor is damaged. Open the circuit, change the wire or incline bracket. After checking all the above, press the key on incline motor.

  The E05 error on your Sunny Health & Fitness Treadmill indicates overload protection. This could be due to several reasons: the treadmill is overloaded, the running board has heavy resistance and needs to be oiled, or the motor is damaged and needs replacement.

  If your Sunny Health & Fitness Treadmill is displaying an E01 error, it indicates a connection issue. Here's what you should do: 1. Check the connection wire between the computer and the control board to ensure it's well connected. 2. Make sure the IC on the control board is properly inserted; if not, re-insert it. 3.

  The E02 error on your Sunny Health & Fitness Treadmill indicates a burst clash protection issue. This can be caused by: 1. Bad contact with the motor’s open circuit. Please change the motor or check the connector. 2. A punctured power tube. Please change to a new power tube or control board.
