koshinal :

there could be a number of things at fault and to positively find the part that is faulty takes special tools, its could be, faulty air pressure switch which is operated by the ventures in the fan make sure the connecting tubes are not blocked or damaged, then the ventures inside the fan are clean and in good condition. there are 13 screws holding the front panel in place are they all in place. light a match turn on the fan and run the match around the seal if the flame is pulled into the boiler then the seal is not good this can stop a ravenheat from firing
