By the way, I really appreciate your videos as they give me a better understanding of how the systems work, & when to call a professional. I was an electronic technician as a young man, but this is a different world.
I had the same problem and then found out later that it was moisture in the gas line when it got cold it froze it and limited the gas from coming in but only occurs when it got below freezing maybe that was the case I don't work on too many of them sanely lot of heat pumps and electric heat I work in Central Florida this is a great video and showed me what the check for and what might be wrong
I want to thank you for these videos. I found your page and have been studying you/them trying to learn as much as I can. I new to this career and don’t have very good knowledge of how to fix things yet. I remembered some of the tricks and steps you use while you fix things and because of that I was able to successfully fix a couple No-heats today. On future videos could you explain diagnostic things more or speak on your habits or good practices more too? Keep up the great videos! Thank you
I think you had check the CSPSC recall list on consolidated furnaces, this unit doesn't have the NOX rods listed in the recall, the flame dancing shown in the video is indicative of the crack in the expansion joint in the fire box. The failure, cracking of the joint is from the fatigue of the metal...camera check it, or replace the furnace, it is a safety issue.
That's one of those Consolidated Industries furnaces that were sold under various names between 1985-1992. They're notorious for having cracked heat exchangers and CO problems. The low NOx models found in California are well known for starting fires. It should be replaced ASAP.
It looks like a Premier or Consolidated Industries which are on the recall list for California for Nox Rods that burn through the base and start fires in homes. Time to Replace
A gas furnace needs SECONDARY air to breath is there a confined space application exsist? The blower when cycled on dances the flames as you seen. Without tearing it to it a whole lot more a goid safety decision was made. Just curious of what was making it dance other than the blower? I had a eve vent blow air in an attic before making the flames dance other than the blower. Mmm makes you really think on this one. Thanks for sharing and can't wait for a follow up on the install.
Of course it wasn’t going to fire well! The jets were blocked. You cleaned them and it worked! They were small to begin with and 10-20 percent blockage was significant. No drip leg, there’s debris somewhere. Plus, there could be other regulator blockage. Just a good cleaning on everything and good for another 28 years.
Looks like the tile business can be a lucrative one. Almost thought this case was going to stump the great HVAC detective, but he somehow solved it as usual.
I called Summit and asked what's the difference between this Pertronix ignition coil, and this Summit one that seems to have all the same statistics? The guy said "$15 and a Pertronix sticker." Sold. 😁
It doesn't take much to turn the gas off sometimes. I Remember when my Family was raising Chickens for People to eat, Ice froze over the gas Regular and turned the Propane off to Our Chicken Houses Houses.
Your natural gas may be from a different source, but here (Texas) we can't use copper for gas lines- the copper will flake on the inside and clog the screen in the valve.
Has Ted ever said why he jumps these things out so often as opposed to setting the thermostat to call? I always made sure the thermostat was calling for heat or cool before going to examine the equipment.
Thanks for a great video I also work on a lot of package unit cuz their trailers here in Central Florida can always learn more so I can learn something everyday I'll have it made
I don't know if this will help You and it might not be cold enough there for it to happen. We used to be poultry farmers. We had big heaters that ran on propane to warm the Chicken Houses with. One year We had a lot of snow and ice. It kept freezing and throwing. We had ice melting off of the roof and one year the ice melting froze over the gas pressure regulator air vent and cut the gas off and We had some cold Chickens. Luckily they didn't die, but it actually did it a couple of times and Dad finally figured out what was going on. He took some tin or some kind of metal and fixed it where it could get air but the ice couldn't freeze over it anymore. I hope it can help You some day.
small blue flames = lack pf gas flow or too much air mixing (non-adjustable air burners) so lack of gas flow only thing it can be. clogged burners would be partial lit, large rich yellow flickering flame and sputtering small blue to yellow down popping down the burners. only other thing I can think of is the inducer flowing way more than it should, but whole burners would normally light and have dancing tall flames.
Consolidated Industry furnace, fortunately this one is elevated off the attic floor and be that as it may I would still recommend replacing this because of the age I believe its been at least 25 years since they made these and second they are notorius for overheating
I like your service van with the doors that open from the outside. I’ve never seen one of those in Oklahoma. Where do you get that type of van? I heard you say you’re getting a little old for this. I am 72 and I still do it. I don’t know anything else.
I leave my caps on the refr wrench,I have to do things like that to keep from losing them or not getting them back in valve, dear god don’t put on ground you will kick them and never find them. Always have some caps in truck for back up fellers. Pro tip...
Great video for sure. Understand how and why this ended where it did. But, any thoughts on what the root cause might have been beyond what was shared??
Being the airflow to the house is never supposed to see the burner chamber and that there is fan air getting into there tells me possible busted heat exchanger
I know this video is well and truly in the past - leaving aside the problems you found, the diameter of the gas supply just looks too small, also is there not a gauze on the gas inlet to the gas valve? May I ask why you do not rig up a combustion analyser - or did you just not show it?
Unless they did a DIY switch from propane to gas.... kidding, but could it be poor flow on the induced draft, partially blocked flue? Crud on the blower wheel??
My furnace is old like this, it has a bar-b-que thumb push sparker to light the pilot light. It is a pain in the butt sometimes to get it lit. Any suggestions to change that situation would be greatly appreciated!
that's a toss up, is gas valve not regulating right when cold or is it upstream regulation/gas pressure loss at meter or other high usage appliance. something like, someone installed a modcon water heater and not check total volume? otherwise I'd suspect gas valve regulator or stuck solenoid, even though it seemed to clunk loud enough to be fine. intermittent fun times :)
@@specialK_hvac if it's below the 7" the gas company is supposed to supply thru the meter when all units are running , you are paying for gas you're not getting. Some units need a minimum of 5" to run. I installed a rinnai tankless and was having trouble getting any volume out of it. While it ran the supply pressure dropped to 2"wc. They need a minimum of 5
Ted, I was surprised at you. Copper gas line oxidizes on the inside, should have taken that out, put in a flex, also no dirt leg. When I worked for a gas co. in Pgh, we would look for no more than 1 " w.c. over a control when firing. That was a good unit in its day, but now is the time...
my vote : shitty burner design them burner boxes seem like a lot of wide open space to be pushing air out of to get gas into makes it light super slow or in this case sometimes not at all
I love how everyone is a friend or a neighbor. haha You are the best....
By the way, I really appreciate your videos as they give me a better understanding of how the systems work, & when to call a professional. I was an electronic technician as a young man, but this is a different world.
As always love your commentary as you work explaining and teaching all those that watch if they care to learn.
6:05 He calls it suspicion. I call it years of valuable experience. Happy New Year sir and thanks for your videos.
Ty. I appreciate your detail and work ethics. You really like to do things the right way. Be blessed.
Despite it being an old beast, I really like the design of that furnace. Fairly easy to maintain and that sparkplug-style thermocouple is cool!

Always good to have a friend in a trade that you're no good at. Thxs for the vids!
A old Bard furnace now they only make the wall mount heat pump and A/C units never saw one of their FURNACES before looks interesting design.
we're not suppose to use Copper in Gas line, in New York as of the 70's black iron only. With a drip tube
Up here they flag copper pipe for gas ,some companies here will not work on units pass a certain age if I recall right .
It was just wore out after 28 years! Imagine that! Thanks for another awesome video! Happy New year Ted!
Could there be the correct pressure at the inlet side of the valve and restricted volume? No drip leg.
That's one of those Consolidated Industries furnaces that were sold under various names between 1985-1992. They're notorious for having cracked heat exchangers and CO problems. The low NOx models found in California are well known for starting fires. It should be replaced ASAP.
I had one the other day that was natural draft I had to condemn. Not only was the exchanger cracked but the housing was as well
Nice cars
Happy New Year

Just got done working on a 52yo Rheem. Manufactured in 1968 lol!!!

I enjoy your videos! Wishing you a Happy and safe New Year!!
0:49 this guy must be where im from around Akron Ohio because I noticed thr summit racing sticker.
I called Summit and asked what's the difference between this Pertronix ignition coil, and this Summit one that seems to have all the same statistics? The guy said "$15 and a Pertronix sticker." Sold. 😁
Summit sells stuff on the internet all over the country; he's probably just one of their many customers.
Everyone has Summit Racing stickers. I have a few of them on my tool boxes and beer fridge, and I'm in Ontario Canada. :O)
Happy new year everyone.
There's a location in Northern Nevada too
good video greetings from houston tx

Probably personal preference. I always jump a furnace cuz I have more control over it
Was hoping I would have a good youtube video to watch this evening... Just on time!

Wow, what a maze to get to the furnace!
I think it was Brad ,HVAC from SC that had the case. Hope You have a Great New Year.
You too my friend !! Yes I think it was brad I saw with these cases first.
Bad heat exchanger I would think with those dancing flames when the blower fan kicked in.

Suspect sticky gas regulator.
Pilot flame seemed to remain but regulated gas to burners was low.
Pilot flame takes supply pressure,it seemed correct.
Great video for sure. Understand how and why this ended where it did. But, any thoughts on what the root cause might have been beyond what was shared??
Being the airflow to the house is never supposed to see the burner chamber and that there is fan air getting into there tells me possible busted heat exchanger
ditto, I heard the valve open and the burners light on first and second ignition. surprised it light at all lol!
Happy New Year Ted
I'll bet the only exercize he gets in that room is moving that stuff down the stairs... LOL
No Drip Leg.
I was wondering about that too, in
Texas we have to install just before the gas valve.
When I run across dirty burners like that, I include blowing them out with compressed air or nitrogen.
I know this video is well and truly in the past - leaving aside the problems you found, the diameter of the gas supply just looks too small, also is there not a gauze on the gas inlet to the gas valve? May I ask why you do not rig up a combustion analyser - or did you just not show it?
Nice video
Good job
Do yall ever get snow there?
Unless they did a DIY switch from propane to gas.... kidding, but could it be poor flow on the induced draft, partially blocked flue? Crud on the blower wheel??
Looked like the inlit psi dropped when you first fired it or the gas valve is hanging up
do you have a combustion tester, they can save alot of time.
A drop of pipe dope when replacing the plugs
My furnace is old like this, it has a bar-b-que thumb push sparker to light the pilot light. It is a pain in the butt sometimes to get it lit. Any suggestions to change that situation would be greatly appreciated!
I could see touching the insulated pipe, but not the single wall stuff.
I've never seen a furnace with burners like that
I'm curious what the co2 level was with the burners not lit?
That cobra though…
that's a toss up, is gas valve not regulating right when cold or is it upstream regulation/gas pressure loss at meter or other high usage appliance.
something like, someone installed a modcon water heater and not check total volume?
otherwise I'd suspect gas valve regulator or stuck solenoid, even though it seemed to clunk loud enough to be fine. intermittent fun times :)
Shouldn't the supply pressure be 7" for nat gas and 11" for propane?
Give or take a little yes. As low as 5wc for nat and as low as 10wc for propane
@@specialK_hvac if it's below the 7" the gas company is supposed to supply thru the meter when all units are running , you are paying for gas you're not getting.

Just curious what year did induced draft heater systems come out?
Not sure, but I've worked on furnaces with induced draft motors from the early 80s.
I worked on one from 1989
Would you be able to share the model # of that nutdriver? I think it might be just what I am needing. Thank you.
This one had you really working huh
Good work Ted... One light comment...He was a buddy when you pulled up, and a "customer" when you left...ha
Was it missing a drip leg? Why didn't you out a camera in there while you had the burners out?
I was hoping you left your manometer hooked up too see maybe the gas valve not opening up every so often.
Factory 5 Racing love there cars live next to there shop in wareham ma i did all the finish carpentry there there shop is insain
Is that a century?
What brand is it
What brand made this furnace?
Manometer do do do do do manometer do do it do.😂
Which Klein screw driver do you use its magnetic I like it
Looks like this it may be this one www.amazon.com/dp/B07D4M51DQ/ref=cm_sw_r_cp_apa_fabc_heq8FbE54360R?_encoding=UTF8&psc=1
It’s a Klein hvac 8in 1
Sluggish gas valve due to age? And of course a cracked heat exchanger to top it off as well. 2 problems I feel.
And low gas flow due to it being so cold and yes gas can freeze like in dallas
It's one of those consolidated industries models
Heat exchanger going bad!
Finding the issue with this 28 years old furnace was a challenge. Changing it is a wise decision . Good luck 😊

I don't think much of Harbor Freight stuff either.
I'm pretty sure that's one of the recalled Consolidated horizontal furnaces. Definitely need to replace that ASAP.
It dosen't look like that thin wall is attached.
Looks like a propane set up with that copper pipe.
my vote : shitty burner design them burner boxes seem like a lot of wide open space to be pushing air out of to get gas into makes it light super slow or in this case sometimes not at all
Inlet inlet inlet get it?
Sounds like its a little Crusty Mr. GRINCH.
Nice manometer
Good job.
Cowboy is on the job !!
Replace it ted they got there money's worth from that furnace.
there is no drip leg on that gas piping
And ? Your point ?
@@TedCookHVAC when you see deficient work, aren't you responsible to upgrade? The lack of a drip leg can allow contaminents to enter th gas valve
Looking for a salesman?
👍 🐕
Leaf blower
what i dont get is you didnt even bother cleaning the flame sensor. 9 out of 10 times thats the whole problem. oh well nice sale.
Flame sensor ??? You mean thermocouple ??? .... this is an older style furnace.... look closer.
