Went from erratic operation to none. Resistance across original return thermister dancing but seems ok. Anyone have any ideas. Primary pump operational.

    Skip that... Went back for followup eval... Not obvious, but flue gas temperature sensor under upper cover snapped and was sending vapor and moisture over upper control board. Integrated relay on board faulted.
