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 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 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.
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.
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.
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
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.
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. 😁
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.
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.
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
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.
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.
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
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.
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??
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.
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 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?
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.
@@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
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...
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 :)
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!
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
