I'm pretty perplexed that a 6 year old furnace, one I shopped for and picked, specifically because it was one of 2 models a the time that had all stainless primary and secondaries. Well, the rollout sensor starting tripping, too much heat over the burner, I'd reset, it'd be fine for a couple days, trip. I swapped the sensors, still tripped after a few runs. So I called the guy. 15 minutes after he gets here...yeah, you need a new secondary heat exchanger. WTF? I hardly used the thing too. Even he was scratching his head. "Never seen this on these models, ever". Well, it must be true, because nobody has the parts. Has to come direct from factory. Wednesday. THat's nice, 5 days with no furnace. Oh well, at least I've got wood heat and that thing is under warranty still. They're going to replace the burner, primary and secondary exchangers to ensure the problem gets fixed.
My stove can keep up fairly well above 10F. Below that, it's losing the battle in this 2400sqft house with 28' ceilings. Forecast here is low of -12F on sat night, high of 1 on sunday, low of -10 on sunday night. Awesome time for this to happen.
Well, I can run the furnace if I bypass the limit switch and supervise it, there's nothing but sheet metal up there, just a bit of flame blowback where it's not supposed to be....and it's definitely not burning right, but it's not a cracked exchanger or anything, just not burning efficiently, they actually can't surmise what may be wrong with it. I may run it in the morning for an hour to bring the house back to temp. Yes, of course I'll watch my carbon monoxide detector while doing so.
Furnaces used to last 30 years. WTH happened. The reason I replaced it in this house is because the 11 year Bryant that was in here when I bought the house had a solid block of rust for a secondary exchanger.
