I have no idea. The Trane unit was left of from a DOT job. I bought all the equipment as a package for a substantial discount. The DOT changed the project - deleted AC for the locker room in return for something I can't remember - maybe marble thresholds or something like that. So I had the condensing unit sitting in the shop waiting for a home for the next year or two.
One day I installed it for my second floor system. Started and ran well all summer. Need spring the compressor was bad. Over-the-counter to Trane and the next compressor ran well all summer. Next spring the compressor was bad. Trane exchanged it under warranty again and it ran well all summer. New spring the compressor was bad. I was at Trane for another new one and I was joking around about all the bad compressors. I had done all the work and I know it was impeccable - so what else is it but the compressors.
Oh; I forgot - the failures were all different. Stuck, no pump, burnout. Friggin job looked like a test lab - I am monitoring everything possible by the second year.
So anyway the Trane manager overhears my conversation at the counter and denies further warranty. He and I go back and forth and he says: "I don't give a damn about warranty! You're Paying for this one! You obviously don't know how to install a compressor right!"
"Shove it up your ass pal! Your piece of shit compressors obviously aren't worth a puddle of cold piss."
That was Lyon Conklyn in Delaware - not Tozour Trane.
Stopped at United Refrigeration, grabbed a Copeland, and it never missed a beat in that Trane condensing unit as long as I owned it - and was still running the day I changed out the condensing unit for a 1.5 ton Goodman HP. That 1.5 Goodman has been there for years now.
Trane effed me out of $800. on another warranty compressor years later too. I wouldn't let Trane lick my ass on a bar bet.

What caused all the issues with the trane?
I too have had more problems with trane (as rare as they are it's surprising) than Goodman.
