Field notes
The setup asks for manufacturer, observed flash pattern, current symptom, furnace age, and labor-market tier. Its sample output pairs a fault label with estimated DIY and contractor costs, while brand links call out board-specific differences such as Rheem Table A/B and Carrier’s short/long amber codes. The page says the saved triage log uses browser LocalStorage and warns that the schematic on the blower door may override a general code listing.
