Endex Auto Tech DCMD76 Treadmill Circuit Board

Endex Auto Tech DCMD76 is a treadmill motor control board that interfaces the stepper or AC motor with the treadmill’s speed sensor and user interface. Common failure modes include a dead power supply (brown‑out of Vcc), burnt or tripped MOSFETs/relays, and firmware corruption leading to “no motor” or “over‑current” error codes. For first‑check diagnostics, verify 12 V/24 V input voltage and ground continuity; inspect the board for burn marks, cracked solder joints, and damaged ICs; then review any displayed error codes on the treadmill’s LCD or diagnostic port before proceeding to component replacement.[oss-gpt-20b]
