On Nov. 21 our furnace was diagnosed with a clogged secondary heat exchanger, and while CO readings were zero in the house, high levels of CO were measured in the exhaust.

What was that "High Level" number?

Hello rundawg.

CO was measured at the exhaust piping adjacent to the furnace at 4900 ppm.

That's high alright. Thanks.

I believe this is the serial number

That is a serial number, but the middle letter is missing - 4106A04914

The serial number comes up as the 355AAV042060F model.

Don't know the current 2023 program

Pretty much the same - check your inbox.

If you can point me in the right direction, I would appreciate having access to the original source material for this info.

You need to reach out to a Carrier contractor/dealer. They should have access to all the latest information.

We can not pass on to you the "in-house" documents provided to them.

This information isn't to be disseminated to the public, but for Carrier contractors to reference should they come across a unit with secondary Hx issues that falls within the 20 year installation time frame.

Forgive me for being a newbie, but I'm not seeing an Inbox? Perhaps I don't have enough forum participation to merit one yet?

That was directed to VTP99, who I quoted in the post.

Good morning rundawg.
From this is it pretty fair to assume that the current 2023 program still has a provision where the heat exchanger inspection is to be performed by the dealer free of charge?

I know of no program where the dealer has to inspect your system free of charge to determine if it has failed.
