Circuit board "AE0016C 100% original new<br> <br> How to determine the failed controller:<br> <br> E01: communication failure,the individual is a sensor failure;<br> <br> E02: controller failure, we want to know which detector is broken, if E02 is best to first test the motor to see if there are any problems motor<br> <br> E03: Sensor fault; general treadmill will turn a few seconds later, there E03;<br> <br> E04: generally over-current fault, this situation is generally burned components on the controller;<br> <br> E08: There may be a lift motor control fault.<br> <br> Testing the motor is normal:<br> <br> Please make sure that there is no problem with the motor before you place your order. If the motor running smoothly by 5# battery, that means the motor is good. If running not smoothly or do not running, it means the motor broken.b<strong></strong><br>
