Boiler is locking out at random (one second interval flash). Ignition sequence not suspected.
Any regulars working on this boiler have any suggestions as to what the cause might be? Since the fault is random, loath to throw parts at it blindly. Have start same thread if regulars would rather post on combustion chamber.
