Morning Doc, in the grips of another winter/spring sand storm. My furnace quit again this morning, thought I had her fixed last night but apparently I have some condition that is causing one of the limit switches to keep going open. If it’s not a bad switch, it’s either a plugged heat exchanger or vent stack ( which I doubt).
4 grand installed..worse thing is; it was still running when we replaced it. But it was well worth it waiting for the gas bill as a matter of fact.

My old one quit twice, both times woke up to a cold house on a Sunday morning, 10 below the first time, somewhere below the second. First one was a burnt out fan motor, called a few places, said wouldn't have a fan till Monday. Went to a Northern Tool, and they had some generic motors and one fit perfectly, did it myself for under $50. Second time, a bit more complicated. Called a couple places, said double time on Sunday, and they'd have to replace the pilot light with an electric ignition unit, both over $500 to do it, not legal anymore to fix a pilot light unit. Plus whatever the problem was and whatever that would cost. Traced it to a broken wire on the gas valved solenoid, soldered another piece of wire on (my pack rat tendencies came in handy, had some of that wire) and it worked a few more years till I got a new furnace - that repair didn't cost a dime. I don't really like doing that stuff, but sometimes trying to get someone else to do it just isn't worth the cost and hassle to me, so it's down on sore knees more often than not.
