Common failure points for this class of boards include burnt or tripped fuses in the power supply section, degraded capacitors on the input line, and damaged trace connections to the motor driver ICs. First‑check diagnostics: verify 24 V DC rail continuity and voltage levels; inspect I/O connectors and solder joints for cold solder or corrosion; review any diagnostic LEDs or error codes that appear when the unit powers up.[oss-gpt-20b] Post Comment
