Is the fan actually spinning, can you hear it?

Customer: replied 1 year ago.
Yeah I think so. When I turn it on ot sounds like it tries to spark up the pilot and sounds like a fan is running - then comes up with the error light for air pressure switch.
Expert:  Andrew Smith replied 1 year ago.

Ok, the boiler does not know the fan is running.

Try cleaning the fan and the tubes to the APS - if that does not cure it then try replacing the APS itself.
