Or the air pressure switch is knackered.

If the boiler is a Solo 1 and the fan appears to be running o/k, the problem is usually the 2 red & white plastic pipes connected to the air pressure switch (bottom r/h corner ) these either develop cracks where the pipes bend or collect water in them. This will stop the fan operating the air air pressure switch.
