Hi all,
we have a boiler ten years old and after ignition can go into a rapid sucsession of momentary main burner shut downs, these only last about 1 second. the pilot stays alight. we have changed the electrode and lead. PCB, air pressure switch, and the case seal all appears to be in good order. we have also checked the flue integrity, all is good. these often occur 1 or 2 times then boiler settles down, customer thinks it gets worse towards the end of the day
any suggestions. thanks.
