| Symptom | Possible Cause | Solution | |---------|---------------|----------| | No output, status LED off | No power on VCC or module defective | Check power supply voltage at terminals. Replace module if no shorts. | | Output stuck ON | MOSFET shorted due to overcurrent or inductive kickback | Disconnect load, measure resistance between OUT+ and VCC+ (should be >1M ohm). Replace module. | | Intermittent operation | Loose wiring or inadequate signal voltage | Tighten screw terminals. Use an oscilloscope to verify PWM signal reaches 3.3V minimum. | | Overheating even at low current | Wrong load type (e.g., capacitive) or insufficient heatsinking | Switch to soft-start PWM ramping. Add a larger heatsink plus fan. | | Fault LED flashing | Overcurrent or overtemperature trip | Reduce load current or improve cooling. Reset by cycling enable pin or power. |
