How to Replace the Secondary Heat Exchanger On a Carrier Furnace 

Ok, seriously, this young man has more mechanical aptitude than many 25 year HVAC techs I know, he’s going places. Well done 👍

You know a man is good when he makes it look easy 😉

Outstanding presentation, Reuben! And it's great seeing that the whole job can be done in about 12 minutes ;-) You're seriously talented, smart and focused. Everyone associated with you in real life is really lucky. Good luck, man! Have a long and very happy life.

My secondary heat exchanger is plugged. Your video helps a ton

this is the best and not surprisingly shortest video on the subject. watched this and another video on how to disconnect the gas line and pulled my old heat exchanger out in an hour. thank goodness for young people who know how to communicate and edit

Thank you very much for sharing. Few days ago I did the SHE replacement by myself based on your video and very straight forward. I spent almost $1500 tax included on parts, save my a lot of money compare to replace a new furnace ($5000 to $6000). My furnace is out of warranty, it was installed in 1998 but still worth for repair (overall the condition is close to prefect).

Excellent video! I am a do-it-yourselfer when it comes to most repairs. However, I had been very apprehensive about replacing my heat exchanger in my Carrier Weathermaker Infinity, until I saw your video. Everyone had been telling me it was too complicated and not worth putting money into. All the furnace outfits are trying to sell me $8000-$13,000 replacement units. I don't have the money to do this. Thanks for showing us how relatively easy the job is and can be done by us common folk!

I just found a bad exchanger on a Carrier 58MCB060 yesterday. Date code mfd 2006. The furnace overall is in good condition and the primary and secondary exchangers are in stock and under 20 year warranty. Boss wants to try for a new furnace but I think they will be going with the repair. I haven't done a residential heat exchanger in decades since I am now in commercial service for over 20 years. I used to do residential on the old Carriers where you got all of the clamshell chambers and had to screw them to the face plate (yeah, I'm old LOL). This doesn't look too difficult so I hope they do go with the repair and I get to change it. The FRS was tripping. Clear trap, clear pipes with short runs. My Bacharach PCA3 was pegged on the CO even before the blower came on. Tagged it and shut her down. The building has two furnaces so they will be good until a decision can be made. Thanks for the great video.

Screw that. Im just gonna replace the whole furnace. Thanks for saving me the headache

Brother, you have a future on RU-vid. To be successful on YT, you have to be knowledgeable of the topic, show in detail what you’re doing, and you must talk throughout the video if it’s instructional. And you have the gift to gab. And a good editing department helps as well. My Carrier 96 Keeps shutting off and the flame roll out switch keeps tripping. At 12 years old now, I’m guessing it’s the secondary heat exchanger. This is a great video. Thank you.

This video is superb- well done my good man

Thanks, this really helped. I put in my first heat exchanger today.I had only done this with another tech once before, and it was several weeks prior to doing this.

The local Carrier dealer who installed my 58MVP furnace 18 years ago replaced the bad coated heat exchanger FREE OF CHARGE under some sort of extended Carrier warranty AND guaranteed it for the next 40 years. This and other similar videos seem not to mention this.

brilliant channel

Very well done! Definitely not a job for beginners!

Thank you for sharing. Going to try it soon!

Great job man

wow you made it look easy

I found this to be very helpful, i want be doing this job

Hello buddy ✌️ Reuben good video buddy 👍 I hope you had a wonderful Christmas and New year day and I wish you have a wonderful prosperous new year and a healthy one my friend 🙏 god bless you and your family.

Very helpfull video. Thanks boy.

nice job. great knowledge. thanks for sharing

Great video. You make that look easy. I have the Carrier of that furnace. Flame rollout switch trips after running about 10 minutes. Flue CO is around 2000. Intake and flue vents are clear. I suspect the heat exchanger but seems like cost will be almost as much as just replacing the furnace. My furnace is only 11 years old but still leaning toward full replacement.

Reuben knows majic

Nice video. Did you have to notched about 1/4" off the inducer legs to get the inducer to seal properly against the new secondary heat exchanger? Thanks

Amazing!

Awesome, thank you

Your a legend 👏

I like how the 60fps looks.

If the cell panel is sooted up like that it, it must be replaced. Primaries as well as they are also full of soot. The updated coupling box kit is stainless steel, you must not reuse the old coupling box and cold spot baffle kit. It is required to replace the coupling box when replacing the secondary. The entire heat exchanger should have been replaced in this furnace. Carrier is anal on warranty, but if you are with a good part supplier, this won't be an issue. Oh and those small metal pieces on the back of the secondary stay in. The replacements all come with them for a reason. Carrier tried multiple different things back in the day to try and negate their poor design failures. Some models have them and some don't. I have opened a new secondary up and those were missing, had to take the old ones of the first heat exchanger. They have to be there. Absolutely 100% they stay in place.

I have two nineteen year old bryant gas furnaces. The exhaust vent motor blew!. Pieces of the vent motor assembly everywhere. I put a new one in myself (4 screws). Works like new. I was wondering at what point do you buy new furnaces? If I were to replace the blower motor, the vent assembly and the heat exchanger would the furnace go another 20 years ?? Great video! Thx

I loved the puns of payne you popped in the video. You made an impossible job seem simple. This was a painful video. Today I found out 2 furnaces are bad (gas bad) and the 3rd floor one is a side mount Payne and looks just like that. Tomorrow I is going to be a sad day as start figuring out the resolutions. I'm suspecting it's replacement so I started my research tonight. With such a tight space with zone controls too, I suspect I'll be hitting a few roadblocks.

Hi I am from NYC I need to order heat exchanger to my air franc unit

What if the baffle was placed covering the main heat exchanger instead of the secondary?

Did you get the heat exchanger replacement under warranty?

So does this teach people how to replace polypropylene secondary heat exchangers knowing they delaminate when they overheat and the breakdown is corrosive. 2007-2012 carrier 90% need to be replaced with different brand if they utilize poly

What is the advantage of an extension bit?

Nice and easy when it is not connected to anything and in good light with nothing around.

Hi Reuben ,could you please tell me to to remove one of the PVC pipes, the one that is not connected to the Inducer fan Motor ,the one real close to the Gas Valve. Thanks !

You don’t have to take the burner box off at all, that is extra work that is not necessary

With so much soot contamination, isn't it better to replace the primary cells and inlet plate too? I know this is more of a demo to show how to do it and what's done for customers could vary. I assume you're re-using the furnace?

Class action lawsuit on the the Bryant's so I assume Carriers would be covered too. I got my primary and secondary and all the parts replaced for free and did it myself. Not a big deal really. Don't let the sales folks scare you into a new furnace and a $600-$900 gift card. The invoice I got with the parts was $2440........that should be the credit towards a new furnace should you decide to go that way in my opinion. P.S. The secondary is made from poly-laminated carbon steel that separate and plug. That is why they fail.

Also I understand there is an extended warranty because of a class action lawsuit on these furnaces. could it be that carrier would give me a heat exchanger for free or does everything have to go through a dealer?

I have water leaking out the bottom of my carrier furnace. This is what i need. where do i buy a heat exchanger.

Just curious what this would cost from most hvac companies. I would assume we wouldn’t be taking the furnace out of the ducting.

Where can I find and purchase a heat exchanger for my Carrier 58MXA100-16 furnace? I can't seem to find parts lists or diagrams.

These furnaces had multiple recalls with there secondary heat exchangers and comes down to poor design and flaw in materials used, even if replacing it, the new heat exchanger is same design and material and may only last 4-6 years. Usually recommended to just toss these furnaces all together

In process of fixing this myself, I just can’t replace whole furnace at this time but I am in need of said baffle at about the 5:37 mark is it possible that you would know the part number for this baffle because without it I can’t move forward one I removed is trashed😢 thank you for any help Carrier 58MXA100-11116

Yes i cleaned that out and it seemed to dry out for a few days then right back where its leaking

Shame on Carrier. They know this secondary heat exchanger design is flawed, yet they still manufacture it and do nothing to fix it even after it’s taken the lives of multiple people.

Cheaper to buy a new furnace.

Is there a lower cost supplier of these secondaries? I have an account with two suppliers and the one I need is still $1400+ for a 60k/100k.

probably if it's real old, you just replace the whole furnace-right!

why not just buy a whole new furnace & new air duct system?!!!😁

It boggles my mind that companies charge over $5000 for these things.

Wrong. Never replace that junk. Right in the garbage. Install a new any brand and FIX THE DUCTWORK!!!!
