Treadmill “E6” / “LS” Low-Speed Error

Answer: Faulty tach loop means speed feedback mismatch. UpFix repairs the sensor interface and validates closed-loop accuracy on our dynamometer.

Quick take: Board sees a mismatch between commanded and feedback speed.

Possible roots

• Dirty speed sensor disc

• Faulty tach buffer on MCB

UpFix workflow

• Clean and test sensor circuits

• Replace buffer op‑amps

• Dyno‑verify ±1 % speed accuracy
