How to Fix / Troubleshooting
Safety first: Isolate electrical power. Do not run the appliance with covers removed.
Owner checks:
- Listen when the unit attempts to start: if the fan does not spin up at all, note this information for the engineer.
- Check that the flue terminal is not blocked externally.
Engineer checks:
- Remove the front cover and visually inspect the fan assembly for signs of overheating or obstruction.
- Test the fan for correct voltage supply from the PCB and verify tachometer/speed feedback signal.
- Clean the fan impeller and housing; replace the fan motor if noisy, seized, or not achieving required speed.
- Check and reseat the fan wiring connector at both the fan and PCB ends.
Because the fan is part of the combustion air system, replacement should be done by a qualified technician.
