How to Fix / Troubleshooting
Safety first: Isolate power before accessing the fan compartment.
User checks:
- Reset the boiler and listen for the fan starting; report any unusual noises.
Engineer checks:
- Check for correct voltage at the fan terminals when a demand is present.
- Inspect the fan blades for obstruction and check that the shaft spins freely.
- Test the fan speed feedback signal and wiring continuity.
- Replace the fan assembly if it fails to start or provide feedback; if the fan is OK, suspect the PCB.
Fan faults must be rectified before the boiler can operate safely.
