Hi, yes I would still like some suggestions re the boiler issue
Expert:  BillyHvac replied 1 year ago.

The biggest causes for ignition fault are:

Low gas pressure

dirty burner

dirt flame sensor

bad ignitor

Since it happens sometimes and not others I would rule out ignitor. I would use steel wool on all the ignition/metal parts at burner. as well, clean/blow out the burner. As far as pressure, you would need to call for service

Soeme of these also have a screen for the intake air that can become plugged/dirty which inhibits air flow.
