6. Troubleshooting
If you encounter issues with your MaxLite 3-Way LED bulb, refer to the following common problems and solutions:

| Bulb does not light up. | No power to the fixture, loose bulb, faulty fixture, or bulb failure. | Check circuit breaker. Ensure bulb is screwed in tightly. Test bulb in another working fixture. Inspect fixture for damage. |
| Only one brightness level works. | Fixture is not a 3-way type, or the 3-way switch is faulty. | Confirm the fixture and switch are specifically designed for 3-way bulbs. Replace the 3-way switch if necessary. |
| Bulb flickers or hums. | Incompatible dimmer switch, loose connection, or electrical interference. | Ensure the bulb is not used with a dimmer switch. Check for loose connections. Consult an electrician if flickering persists. |
| Bulb is too dim or too bright. | Incorrect brightness level selected. | Cycle the 3-way switch to select the desired brightness level. |
