    Hey guys, I have a Trane XL-12000 gas pack unit with a heating problem. Sometimes the unit runs fine and at other times it won't. The unit is calling for a new board, but I'm wondering if there is something else going on with the unit. Like I was saying sometimes it runs fine and will get the house up to temp. Other times it will come on for a few minutes and shut off, while the t-stat is still calling for heat. It has more problems the colder it is outside. I have checked all of the safeties for continuity and all checked out fine. I pulled the flame sensor out and cleaned it, not that it was really in bad looking shape anyway but I thought it couldn't hurt. I'd appreciate any ideas on what to look for. Oh and yeah I'm a HO that has hung thousands of feet of duct work (mostly commercial) so I hope that will keep me in your good graces with out the HO barbs, LOL! Thanks again with any advice.

    No, but I replaced the pressure switch last year. At that time I was getting cold air because the there wasn't enough pressure to keep the burner ignited.

    If the board says to replace board,do it IF you can pay wholesale for it. other wise get a GOOD Tech to look at it and have him go through it well b/4 replacing board.Did the board say "replase board or external lock out"?

    Solid Red, that code said to replace board. I talked to a tech earlier today and he said to check out the burners and see if they are corroded and to have a looksy at the heat exchanger to see if anything is going on with it. If those things look good then it's probably the board he says. My nephew is a installer and he says that the HE's in a Trane don't last but about ten years. My unit is eleven years old, but I guess I'll find out tomorrow what the problem is.

    Talking Hey kleerline

    I checked the burners and the heat exchanger, and they looked real good, so I replaced the board. Trane must be real proud of conversion kit, for what it cost, the board was very resonably priced however. But it's runnin like a champ. Thanks for your suggestions

    Did I ask for a price?

    You know, maybe the guy that owns this site, otta plainley state that no DIY'ers should post here. Guess I already knew that anyway, but after reading posts here for a couple of years, thought maybe I could get alittle help from some folks that understand that you gotta have a delivery system for a unit, which I used to do a plenty of.
