The GE Procond Elettronica 141914 is the motor‑control board for MC‑70 style treadmill drives, responsible for stepping the belt and coordinating incline motion. Common failures include a dead drive that stops belt movement while the incline still operates; this is usually due to burnt MOSFETs or damaged driver ICs on the board’s high‑current path. For troubleshooting, first verify the 48 V DC supply to the board and check for any blown fuses or tripped breakers; next inspect the motor drive output pins for continuity and look for visible burn marks or capacitor leakage; finally review any error codes flashed by the treadmill’s main controller (often a simple LED status code) before proceeding with component replacement.[oss-gpt-20b]
