Possible Causes
Stuck relay on control board, Incorrect light mode setting, Shorted light control transistor, External control wired to light circuit
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing the light or control board.
Steps to try:
- Check settings: Some Novoferm models allow the light to be set to permanent on via a button or menu. Reset to automatic mode.
- Power cycle: Disconnect power for a minute and reconnect to see if the light behavior resets.
- Test without bulb: Remove the bulb. If the light output remains energized (measurable voltage) after timeout, the relay or transistor is stuck.
If the light circuit is stuck on electrically, the control board will need repair or replacement.
