Treadmill Error E2 – Speed Sensor and Motor Control Problems Explained
An E2 error on your treadmill often points to a speed sensor or motor control issue. Learn to diagnose and solve the problem with our expert guide.
Understanding the E2 Speed Error
An E2 error signifies that the console is not receiving a speed reading from the speed sensor, or the reading is incorrect, shortly after the motor is supposed to start. The system shuts down for safety.
Locating and Inspecting the Speed Sensor
We show you how to find the speed sensor, which is usually a small magnetic sensor on the frame near the front roller pulley, or an optical sensor on the end of the drive motor. Check if it's dirty, misaligned, or has a loose wire.
Checking the Speed Sensor Magnet
For magnetic sensors, there is a small magnet attached to the front roller pulley. Ensure this magnet is still in place and passes close to the sensor (usually 1-3mm gap) as the pulley rotates.
Motor or Motor Control Board (MCB) Issues
If the sensor and magnet are fine, the issue could be that the motor is not actually starting, so there is no speed to sense. This points to a problem with the MCB or the motor itself.
