been going on for about 3 weeks now not consistently either but sometime I go out to load boiler and it has tripped the limit because it has got to hot. has happened about 6times that I know of. cannot figure out why one day fine next it tripped again.
checked (added) water level in tank and bladder, tightened flue nuts, auger nuts, scraped blower off vacuumed out rectangle chamber in front of blower but there was a lot of either water or humidity in there vac bag was saturated pretty bad so I thought problem was rollout device not closing off all way when door was shut letting in air and creating moisture? scraped that gasket off looks good , scraped off fire door, pump seems to be working plenty of hot water inside.
aquastat is only thing left I can assume? but burner works proper at least 50% of time?
if it was a aquastat would I be correct to assume its the one on left that tops out at 180* which it letting go past for the high temp right one to shut down at 200*?
thoughts please
