Hi All, what is the best way to determine the condition of the heat exchanger, we need to replace the evaporator and not sure if it should be a complete replacement of furnace.

It needs to be examined for rust and rust thru.

Visually - from the top with the evaporator removed, or with a snake camera through the limit opening.

that furnace model is decent and has a 20 year heat exchanger warranty (part only), if hxt has failed you can pay labor and replace the hxt.

though once the furnace is more than 16 years old, once the hxt has failed it is better to change the entire furnace.

I doubt that the furnace was ever registered when new , and second or 3rd owner, probably more hassle then itís worth. Iíll try and get a look at the hxt , flame looks good an clean.
Thanks for the reply.

Good morning, I will purchase a snake camera and have a look at the out of the hxt, inside looks good but I can also get a better look into there. Also would like a parts breakdown with part numbers any thoughts?
Thanks

OK.

I believe you'd find the burner tubes behind there.

That the collector box for the secondary heat exchanger - leave it on!
Remove the high limit and insert camera - look along all the bends for rust and holes. Then take a look at tubes.
