I dread replacing those Carrier heat exchangers. I always hope the customer just wants to replace the furnace instead
It’s 26 years old. It’s garbage.
Also, the inside of the exhaust pipe looked to be dark brown, a sure sign of producing c o. Good video, sounds like you have the sniffles, stay safe.
26 years - pretty good
Lucky the rollout tripped. I have video of one that got hot enough to melt the intake and turn all the screws black. The homeowner called the gas company for a strange odor they thought was gas. Gas company shut it down because of high co.
You can easily see the soot at exhaust pipe outside ! The poly coating on those carrier secondary heat exchangers are always going to fail .
I was installing those msa/mca units when they came out lol. I’m so old
A beautiful Michigan Basement
Seems like i find a lot of carrier secondary exchangers either plugged or cracked. Seems to be a recurring theme
Great video! I like the sniff test, keep up the good work!
Original heat exchanger 1994.it did its job.
Good luck seeing the same length of time before failure out of a units installed today!
Sniff test? He said smelled CO but Co doesn't have an odor so what he smelling? Other byproducts but which is stinky??
We saw alot of those failured buggers a few years back. We weren't carrier dealers,so most wanted to check on the heater hanger warranty. Which was fine, service was where we were at more than replacements.
I have replaced so many of those things,only had a couple covered underr warranty, and it's the same thing every time,the plastic lining breaks apart inside and that's all she wrote!
I’m very proud of ya!
Smell of ☠️
Always a quick call and a lead !!!
I've caught carrier heat exchangers starting to plug up in a combustion test. It's going to be interesting to get my first no heat to one that's fully plugged and then some.
at that stage do you get a hot burner box and bad exhaust smell or no outward symptoms.
Cold collector box
Have a Bryant 92% 345MAV furnace from 2002.
I am afraid to see the roll out due to secondary plugged - I will need a couple weeks to get a new furnace and another day to install it.
Visually checked both primary and secondary - did not find anything unusual.
My pressure sensor has 3.05 inH2O on main entry and 0.74 on intake entry.
My exhaust contains 47 ppm of CO (I can probably reduce the gas pressure to reduce that)
Flames look blue with tiny orange.
I do have all parts short of exchanger for my furnace.
What are the since that secondary getting to be plugged before the roll out?
@@azaslavs1 I don't think you have a plugged secondary. 47 ppm is with normal range, possibly a bit over-fired but it takes other measurements to tell.
if it's a 2-stage, make sure you're testing it on high fire.
@@Jon-hx7peThanks! Forget to mention - single stage.
Also I am @ mile high - so do not know if original installation was closer to 0 CO.
Which OTHER MEASUREMENTS should I watch to observe signs of plugged secondary?
He was told that was going to go real quickly back in I want to say late March but you know how Jim is
Carrier/Bryant: heat exchangers ... “some assembly required...” Me: “where is the apprentice?” Or ... “good news, sir/madam, carrier/Bryant is offering a 400$ buy back to replace this piece of equipment.” Lol
Did you replace the heat exchanger? I have a Carrier 58 MCA with the same problem!
Fun fact. One was rated single pipe and the other two pipe. Zero difference between the two model’s other than certification
Those get quoted high for replacement. That thing is junk
It's just done. 👍
Where i can buy a new secondary heat exchanger bryan carrier 58mca080-12 i am in canada and need it please
Not sure in CA. I would think about changing the furnace
Damn i have the same issue and i knew that smell was bad news
I'm working on a Payne 90%er and the thing fires right up burns blue but doesn't put out any heat when blower comes on it has hood airflow but the outgoing air temperature is only 81 degrees and 61 entering air temperature is this caused by a plugged secondary heat exchanger
Yes for sure
You can always tell by that smell
What is the particular smell like? I'm not experienced with the smell test.
@@bradmironik6137 super hard to explain but when you smell it you smell it. I think it kinda smells like silicone caulk when it's wet. Has a very acidic smell to it. Its like trying to explain the smell of something dead. When you smell it you smell it
It a smell you never forget
@@MiHeatingGuy Pussy smell? Asking for my friend Borat.
@@timcat1004 Hard to describe, acidic is probably the best way to describe it. When you smell it, ya don't forget it.
They were told in March it was going and was given a quote
Were you out there in st clair
@@MiHeatingGuy back in in march
I'll answer the phone
@@karlschoen7297 lol sounds about right
Oopf.. nice video!
Could be high winds
no
I am your fan.

If it was installed correctly in the first place this wouldn't have happened. 99.9 failures are due to crap installs.
What did u mean "crap installs"? Pitch of the furnace, proper gas pressure, temp rise?

@@azaslavs1 Try common sense
Nope! Poor design. Epoxy coated secondary that flakes off. I change a couple a week. Compleat furnace replacement.
I could tell you had an idea what was wrong.
Just the age and type of furnace

The exhaust smells something - like smog of water I would say and it is not blue at all.

That was a stupid design. The newer ones have a stupid design on the inducer. I fix them with an original shaft so water don't run into motor bearing
