    Sounds like you need to go to the phone book, open it to the heating or cooling section and scroll down.

    That unit may be in a residental application, But it's set up like a commercial unit. You say you don't do residental so you should know how to work on this one. Your profile was left blank.

    Was the unit subjected to any water ? Power surges ? I didn't see the unit in my book.
    So it must be old, and in need of replacement, Then you'd have a nice clean lennox schematic.

    BTW, you'll need to look up a lennox dealer in the book.
    you have to have a lennox account to get their parts.
    If you try to fail, and succeed.
    Which have you done ?

    Sorry to ask....As for my credentials I have been a Local 250 journeyman for 15 years mostly working on computer room equipt. Maybe the way i asked the question I sounded like I did not know anything..But I will not apolagize for not being familiar with Lennox Equipt or their parts procedures. I looked at this unit in the dark...found the control board model and serial and buttoned it up, then started thinking of who sells far as the schematic goes on the lennox web site I could not download for this unit, so I was just wondering If anyone new of a different site to get one. I have another question why are you guys calling this a commercial application???because its a package?? If this is a stupid question so be it..thats what i thought this site was about helping out. I think some people are to quick to jump down anothers throat without cause. Also I would not be looking to make one penny from my neighbor..just a favor.

    The schematic represents no problem for trained professionals. Call one for repairs.
