Technical description: No signal from fan
What causes this fault?
This fault occurs when the boiler's computer can no longer detect or control the speed of the fan responsible for clearing waste gases. It is usually caused by the fan motor burning out or a loose electrical connection between the fan and the main control board. Without the fan running at the correct speed, the boiler shuts down immediately as a safety precaution to prevent dangerous fumes from building up.
