Digital Concepts MEC8T‑2FMEC8T is a treadmill motor control and power‑supply board that drives the main motor, incline motor, and communicates with the display and sensors via PWM and magnetic encoder signals. Common failures include a shorted motor driver section that disables the main motor while leaving the control panel and speed sensor readout functional; other issues may involve degraded MOSFETs or damaged voltage regulators. First‑check diagnostics: verify 24 V DC input to the board, inspect for burnt components or blown fuses on the motor driver rail, and confirm PWM output and encoder signals are present at the motor connector; then review any error codes from the treadmill’s diagnostic display if available.[oss-gpt-20b]
