How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before accessing the control panel.
Steps:
- Check knob and shaft: Ensure the control knob is not cracked and is properly engaging the switch shaft.
- Compare zones: Compare operation with another similar zone. If only one behaves abnormally, suspect its regulator.
- Access regulators: Remove the front control panel or side panel to access the energy regulators.
- Inspect wiring: Check for loose or burnt wires on the suspect regulator.
- Replace regulator: Swap in a new SMEG energy regulator for that zone.
Warning: Do not bypass regulators; this can cause uncontrolled heating and fire risk.
