I have a trane XE 90 that is mounted in the attic. The unit will run when the heat is selected at the thermostat but the unit does not light and just blows cold air.
Help!
Is this the way we try to help people out? He might just have a burned out glow bar, any furnace can have that. PaulLove the title of your post "trane XE 90 blows cold air

That's what a Trane does, they are junk!
Been here a long time Paul. Long enough to know that a tech will be called in to fix the problem. People can't buy the parts over the counter unless they have the contractor license. In the last month, I've had to replace 4 glow bars, 5 control boards, 1 inducer motor and 3 flame sensors. All on Trane units. It just seems like they have more problems than any other brand I have to service.
Parts are available on the internet. You just have to search. Also 110V upgrade nitride ignitors are now available at some big box stores. Seems to me that possibly Tranes are the majority of your work and that you WOULD see more problems with trane than other equipment. All manufacturers furnaces have failures, there is not one that has fewer failures than another. Most of what makes the difference is how well it was installed.
BTW, flame sensors almost never need replaced unless the porcelain cracks. They are just a metal rod and can be cleaned of invisible oxides and deposits very easily. It is doubtful that you needed to replace all those flame sensors IMO.
