Possible Causes
How to Fix / Troubleshooting
Safety first: If you suspect lightning or serious electrical damage, have the installation inspected by a qualified electrician. Disconnect power before opening the unit.
Steps to try:
- Power reset: Disconnect the opener from mains for several minutes, then reconnect via a known‑good outlet or circuit.
- Visual inspection: Look for burnt or cracked components on the Novoferm control board, especially near the mains input.
- Check supply: Verify correct line, neutral, and earth connections at the supply point. Incorrect polarity can worsen surge damage.
In most cases of surge damage, the control board must be replaced. Consider adding an external surge protector to the circuit to protect the new board.
