7. Troubleshooting
If you encounter issues with your doorbell, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Doorbell does not chime when pressed. | No power to the circuit; loose wiring connection; faulty chime unit; faulty button. | Check power supply at the breaker. Verify all wiring connections are secure. Test the chime unit separately if possible. Inspect the button for damage. |
| LED illumination is not working. | Incorrect LED wiring; no power to LED module; faulty LED. | Ensure LED wires are connected correctly (polarity). Check power supply to the LED module. If individual elements are interchangeable, consider replacing the LED unit. |
| Doorbell plate feels loose on the wall. | Dowels not fully secured; improper installation. | Gently press the doorbell plate firmly against the wall to ensure it is fully seated on the dowels. If the issue persists, re-evaluate the dowel installation. |
| Name badges are difficult to insert/remove. | Incorrect label size; debris in the slot. | Ensure paper/cardboard inserts are cut to the correct size. Clean the name badge slots if necessary. |
