7. Troubleshooting
If you encounter issues with your Kircuit 6V AC/DC Adapter, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not powering on. | No power from outlet; loose connection; incorrect voltage/polarity; faulty adapter. | Test outlet with another device. Ensure all connections are secure. Verify device's power requirements match adapter. Try a different adapter if available. |
| Adapter feels hot during use. | Normal operation; poor ventilation; device drawing too much power. | A slight warmth is normal. Ensure adapter has adequate ventilation. Confirm device's current draw is within adapter's 0.5A limit. If excessively hot, discontinue use. |
| Device powers on but malfunctions. | Incorrect voltage or polarity. | Double-check your device's exact voltage and polarity requirements against the adapter's specifications. |
