Endex Auto Tech DCMD76 0511-JI41 control board

The Endex Auto Tech DCMD76 0511‑JI41 is a treadmill motor control board that drives the belt and incline motors via a magnetic speed sensor and integrated power driver. Common failure points on this model include burned or cracked MOSFETs/IGBTs in the drive section, damaged capacitors on the high‑voltage rail, and worn or broken solder joints around the motor driver IC; overheating of the board often results from inadequate heat sinking or a failing fan. First‑check diagnostics should verify that the 48 V DC supply is present and stable, inspect the board for visual signs of component damage (burn marks, bulging caps), and review any error codes displayed on the treadmill’s LCD or communicated over its serial interface.[oss-gpt-20b]
