8. Troubleshooting
If you encounter issues with your dimmer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power, incorrect wiring, faulty bulb, dimmer failure. | Check circuit breaker. Verify wiring connections. Test with a known working bulb. If problem persists, consult a qualified electrician. |
| Light does not dim or flickers. | Non-dimmable bulb, incompatible bulb, load too low/high, minimum brightness not adjusted. | Ensure bulbs are explicitly marked as dimmable. Check if the total wattage of bulbs is within the dimmer's specified range (3-60W/VA for LED, 7-110W/VA for Halogen/Fluorescent). Adjust the dimmer's minimum brightness setting if applicable. |
| Dimmer feels warm. | Normal operation, overloaded circuit. | A slight warmth during operation is normal. If the dimmer becomes excessively hot, immediately disconnect power and check the total load connected to ensure it does not exceed the dimmer's maximum capacity. |
