Part 3: interestinger and interestinger...
Okay, solved the low pressure. Rain, wind, significant chill, and being a bit "house" bound seems a more reasonable explanation to the sudden upsurge in propane consumption than a leak.
NOW, furnace fan again cycles on but burner doesn't ignite (again, and of course, on a Friday night). Couple on/off cycles on the thermostat and same result. Two hours later, furnace starts up. Then doesn't. Then does. Was thinking a bad thermocouple but I don't think they fail intermittently. Same with the thermostat. Good gas pressure and fire to burners and water heater.
Opening up the furnace enclosure (while it's working for now), as I expected, nothing jumped out as an obvious problem except that there were at least two dozen stink bugs nesting inside the space between the metal access door and the plastic component box door. An absolute explosion of the critters here in Oregon over the last couple months. Now me thinks, maybe this is just a couple suicidal stinkbugs crawling up into the combustion tube? Good dose of insecticide as a preventative, maybe? Thoughts, comments, howls of derision?
Question: better to be a successful pessimist or a failed optimist?
