Trane heat exchangers

[eliteair]

Just found one with a crack in the header,and a crack in the inducer bracket that hold the inducer motor will put pic on.

That is pretty common with tranes design and first thing I check. But my photos where a result of hairline cracks in the secondary plastic collector box. Only way to see it was to pull it, not sure if u could see the detail needed with a snake camera but I would like to try.

Yes I have noticed them with pin holes ,heat exchangers aren't mad like they used to be and the manufacture doesn't carry the 20 yrs like they use to ..Regards

I am not sure everyone here would agree with me but why not spend a couple extra dollars and make that cover out of stainless or anything other then plastic and I wonder if they would not be having this issue anyone else fell this way?

had one today that was leaking water on the right hand side above the blower motor in blower compartment.(tux080c942c3) i think its the inducer. alot of sloshing on startup.unit plumb and level. upflow.drains and traps clear. please advise if im wrong. rescheduled pulling inducer and gasket replacement. all ca readings were good. 0ppm in home

Hey Techwiz...,Goodman has a lifetime on there H.X.

Hey Techwiz...,Goodman has a lifetime on there H.X.

Most manufacturers have a 20 year or lifetime warranty. certain carrier models have only a 10 year.

It doesn't matter the model. I have seen them on every model both 80 and 90 %. Here is a picture I took using my see snake and phone. It right underneath the burner entry Attachment 335651

Has anyone found any of these lately?

Good lord, glad I found this thread! This answers my question about how Trane HX's are holding up... Now i'll be keeping an eye out.

Are these failing HX's you guys are finding not getting enough airflow or something? (in other words any of them fail with proper airflow/ductwork etc)

There is no reason outside of design or quality of materials.

Found this one today. 9 yrs old.

I assume that is the tail piece from secondary to comb blower motor?

Yes it is. That was the worst of it, but it was cracked a few places. They were all where the secondary screws to the faceplate.

Did u happen to check the plastic cover plate that have a dozen or so screws in in that covers the actual secondary hx when I find tail piece issue I usually see that but not always

If I need to take the actual faceplate off then no. I'll pull it and look at it when I pull it off my van in the am.

Sounds good. I been wondering if a inspection camera thru the limit switch would work at all in helping to find these issues as well

I've found that Tranes are pretty consistent on O2 content. run 10% in flue. if its higher than that, likely a leak in hx. also, CO will be up sometimes as well.

It should but it wod depend on the camera. My dewalt wouldn't fit.

Everyone seems to be assuming that having a hairline crack in the heat exchanger is an extremely dangerous thing. Can combustion chamber air really get through a hairline crack when the combustion chamber is at a negative pressure relative to the house air? Reference - http://carbonmonoxidemyths.com/m/Myth-1.html.

If this is such a dangerous thing, why aren't heat exchangers designed to be inspectable? Why are cracks so hard to find? Doesn't that suggest that cracks are likely to exist in many units out there that are thought to be good? Wouldn't this be a liability for furnace makers? (they've designed heat exchangers that can't be 100% reliably inspected for cracks that could lead to CO poisoning). The HVAC service guys (probably most reading this) are obviously worried about their part in this liability. What do the furnace design engineers have to say about this?

I don't assume it is a dangerous thing,, I assume it could lead to a dangerous thing. If it is cracked it is condemned. If I make light of it and someone dies,,, it would be on me as I am the professional.
