Hi all, I have a Carl Lewis MOTC66 treadmill. After some time the control board gave up .. probably overheated after 45 minutes in use. I ordered a new one but its gives error code E03 at the speed. When you turn on the treadmill it counts down for 5 seconds, then for one second it turns the motor but then stops (relay click). I've cheked the cables and the opto sensor for speed at the motor but they are fine. Anybody have an idea? Please mail me via: pa3fxo (at) hotmail.com many thanks in advance! Regards, Cees

Dear Sir: This is probably a faulty speed sensor or the speed sensor is not plugged in properly. Its also possibly a faulty motor control board or lower board. The error codes will differ between makes and models but could be e1. . sincereley.God bless you. ernesto cuadramanagua, nicaragua c.a.
1)probably a faulty speed sensor 2) speed sensor is not plugged in properly. 3)possibly a faulty motor 4) Main control board or lower board. The error codes will differ between makes and models but could be e1. Check this video for speed sensor. http://www.youtube.com/watch?v=23ZgWaVEQjA
adjust the speed sensor:Move the motor to slacken the pulley, then lift the motor to get underneath. That is where the treadmills speed sensor will be located. It is usually a square or rectangular shaped green module with connectors at both ends.
Finally after you did the adjustment you can conclude: A) Faulty Speed sensor B) Main Motor faulty C) Main Motor Controller faulty.
attached block diagram for treadmill that I did for any treadmills,see how the Main Motor Board has function for 90% of the treadmills. sincerely. E.CUADRA MANAGUA, NICARAGUA. C.A
I also have this problem. I rang Carl Lewis Support and they said to check the connections on the circuit board (Located in the floor panel next to the motor). If the treadmill had recently been moved something may have been dislodged. I checked mine and found a few loose wires and plugged them fully back in but this didn't help my treadmill. I'm awaiting a response from an e-mail i sent them now.
