Treadmill Speed Error Code – Causes, Diagnosis and Repair Solutions
Any speed-related error code (like E2 or LS) on your treadmill points to the speed sensor, motor, or controller. Learn how to diagnose the problem.
Decoding Speed-Related Errors
Errors like E2, LS, or "Speed Error" all indicate a failure in the speed control loop. The console commands a speed, but either doesn't see the belt move, or sees it moving at the wrong speed.
The Speed Sensor: The Most Common Failure Point
The vast majority of speed errors are caused by a faulty, misaligned, or dirty speed sensor. We detail how to locate, inspect, clean, and adjust this critical component.
Motor and Drive System Checks
If the motor isn't running at all, the sensor has nothing to read. Check if the drive belt is intact and that the motor is receiving power from the Motor Control Board (MCB).
Diagnosing the Motor Control Board (MCB)
If the sensor is good and the motor has no physical impediment, but it still won't run correctly, the MCB is the most likely culprit. A failure on the board can prevent it from powering the motor correctly.
