8. Troubleshooting
If you encounter issues with your HBN timer switch, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn ON or OFF. | No power to the switch; incorrect wiring; faulty switch. | Check circuit breaker. Verify wiring connections are secure and correct (Hot and Load). If issues persist, the switch may be faulty. |
| Timer does not count down or stops prematurely. | Timer not wound sufficiently; internal mechanism issue. | Ensure the knob is rotated clockwise past the 10-minute mark before setting the desired time. If the problem continues, contact support. |
| Timer turns OFF but then restarts or does not stay OFF when set to 'OFF'. | Knob not fully rotated to the 'OFF' position; internal mechanism issue. | Ensure the knob is firmly rotated counter-clockwise to the designated 'OFF' position. The timer should not tick when in the 'OFF' position. If it continues to tick or restart, contact support. |
| Loud ticking sound during operation. | Normal operation for a mechanical spring-wound timer. | A slight ticking sound is characteristic of mechanical timers as the spring unwinds. This is generally not an indication of a fault. |
