Endex Auto Tech 0511-JI31 Circuit Board

Endex Auto Tech 0511‑JI31 is a treadmill motor control board that manages start/stop, speed ramping, and safety interlocks via a DC motor driver circuit. Common failure modes on this class of boards include burnt or tripped current‑sense resistors, damaged MOSFETs or IGBTs, and degraded power‑rail capacitors; users often report “no motor response” after a short surge or overheating during prolonged use. First‑check diagnostics: verify the 120 V/240 V input supply with a multimeter, inspect all surface‑mount components for discoloration or burn marks, and confirm that the motor drive outputs are present and within spec; if available, review any error codes displayed on the treadmill’s LCD panel.[oss-gpt-20b]
