    Unit is 21 years old. In auto when a call for heat occurs, furnace will light then after several minutes shut down on what I presume is the high limit because the blower isn't getting a signal to run. However, if I flip the t-stat fan switch from auto to on before furnace shuts down then the blower runs and I have hot air. T-stat is a 6 year old digital Duracraft with fresh batteries. I've never had a problem with it. A week ago the unit ran fine in AC mode. A cursory inspection by my untrained eyes couldn't find any loose wiring connections at the t-stat or at the furnace. Furnace is burning nice blue flames with no CO in exhaust or airstreams. A tech is coming tomorrow to fix/repair. Any opinions on what is wrong?

    Welcome to HVAC TALK.

    The best thing to do is wait for the tech to show up to diagnose your unit, as it's hard to test the equipment over the net.

    At 21 years of age, I wouldn't waste too much money on an expensive repair. You might want to start getting some quotes for a replacement.

    I would start getting quotes before it gets much colder

    Sounds like a small,inexpensive repair,so don't condemn it just yet. but like others stated, start saving for a new system. They don't all last 40 years....
    If everything was always done "by the book"....the book would never change.

    Those weren't 'hot air' baloons, huh? I kind of miss them.
    Your messages are right on as usual, and not hot air.
    Don't confuse me with facts, my mind is already made up.

    it is a pretty simple fix, but get ahold of your nearest American Standard dealer.

    Ok if its a simple fix then what is it? Not to worry if you think I'm going to attempt to repair it myself. I have had recent issues with incompetent techs in my area and I'm trying to protect my wallet from dishonest people. I'm out of town for two weeks on business so the repair will take place while I'm gone. I still haven't paid for my 5 month old Trane system and I don't want to waste money on this system (my house has 3) if it truly is unsafe or uneconomic to fix. If its merely an hour or so of tech time to replace a relay or such then I must go that route at this time. I use this site to get accurate advice on probable causes and practical solutions. Thanks for the replies.
