Glow worm 75 is not lighting - pilot & fan are ok??

The problem could be the pcb, but it could also be the air pressure switch. I believe the 75 does have one, although I know the 80 and 100 do not.
you can normally hear a click after the fan reaches its correct speed, this is the switch operating, although this does not rule out the contacts on the aps. this would have to be electrically tested.
hope this helps
