- Attention DIYers: you attempt anything shown in this video or mentioned here entirely at your own risk. Know your limits and when to call a professional.
I first noticed this Goodman 96% AFUE furnace acting up when it didn't respond to the thermostat's request for heat. Later, I heard it try and fail to ignite. Fault codes 1 (retries exceeded) and 7 (low flame sense signal) were recorded. Try as I might to catch it in the act, it wouldn't mess up on camera.
Let's see what all might be wrong with it, and if I can fix it. Furhead, the Keykeeper and a dead mouse also show up in this video to lend a hand and provide some amusement along the way. The dead mouse didn't actually help out very much, but as with so many other dead mice, that's a common problem.
Gas pressure looked acceptable, all other subsystems in the furnace appeared to be working as intended, and the flame sensing rod was cleaned. It looks as though the burner box, if not the "inshot" burners themselves, could also stand to be cleaned.
Of the two furnaces in the building, this is the one most used and depended upon, as the other is shut completely off when the building is not in use. (I think they should consider leaving the other one on and set at a lower temperature as a backup.)
At some point, I should probably get and educate myself on the use of a combustion analyzer for furnaces. They are seriously not cheap, though.
I should have brought my own flashlight. I forgot that I have a search magnet. It's a large one I got at an auto parts store many years ago and comes with the added bonus of the magnet head lighting up. It would probably have been too large for this job, so I should probably buy a smaller one or steal the Keykeeper's magnet when he's not looking. I did try poking the search magnet behind the draft inducer, and the screw refused to give up and stop hiding back there.
The Hammond organ is still going strong, in case you want to know.
The Curbled Electrolux vacuum cleaner ( • Curbled Electrolux Vacuum ) is also still going strong. Not even a basement flood in 2018 could kill it. You should have seen the dust that came out of it after I let it dry out and tested it. Evidently it was the truth at one time, that nothing sucks like an Electrolux!

Awesome vid. Furhead approved
Hey Furhead how you been? It’s been a very long time.
Good to hear from you again bill, missed the variety of videos you used to bring to us, thank you 🙏🏼
It's good to have a little fear when working with gas appliances even if you're an expert. Keeps you alert and aware.
Always interesting to see how things are done "over there"! Here in Scotland most applications are boiler systems with radiators, or heat and AC systems running purely on electric with ceiling mounted ducts/vents in office buildings.
You will find plenty of hydronic (boiler) heating systems here in both residential and commercial settings. I didn't train as extensively on those and therefore don't have a great deal of knowledge with regard to them. (In other words, right now I wouldn't take on boiler work.)
Electric heat is much more common on this side of the pond where electricity is cheap, such as in the Tennessee Valley. Heat pumps are also much more common further south, where it doesn't get so cold that they no longer function well.
You apparently have a career in HVAC. Awesome. Also, I love every video you post. Kind of bummed that you don't post more, but I get that you don't have time. I just appreciate anything you have time to share with us.
My "real job" is still very much in IT and computers. It keeps me very busy. I'm frequently exhausted when I get home.
The HVAC thing didn't turn out like I'd hoped. It's just something I do very occasionally on the side and that is about as far as it has gone. (For a short time, I worked for two very bad companies, both run by dishonest and shady people. In spite of talking to many, I couldn't get any "good" HVAC service companies to give me the time of day.)
Great to see a video from you again. I subscribed for the computer content but stuck around after discovering I might learn a thing or two about whatever you might have been into on that certain day. Seems you have a wealth of knowledge, yet are humble and admit when you don't know. Also always willing to learn. Hope to hear more from you. Hope you and the family have had a great Thanksgiving and wish you a very Merry Christmas if we don't hear from you before then. Take care.
Thanks for taking the time to write and the kind words. They are appreciated. The videos usually track closely with what I'm doing or focusing on in real life, when I have the time to make them. Lately that's less than ever. I also try to have fun with them.
IT stuff is my day job, the HVAC/R and everything else are hobbies or side jobs.
Good to see you back, UXWBill!
Remember the most important post-DIY phrase: "Smoke test!"
I suppose someone just had to do it.
@ymxctrails No, it's a stupid shtick that's gone on far longer than intended. I'd even say it's gone on longer than it was funny, but the viewing populous apparently disagrees.
(Now that I've said all this, please don't anyone argue the point. What I've said about my feelings regarding "smoke test" are the truth, so it's really _not_ up for argument. And yes, I am taking a pretty hard line on that.)
Very instructive video on how something so simple like that could affect the entire furnace hope to see more videos soon
I know you said not to work on this at home but it’s the dead of winter and my lady is sick in this cold house. Eggs is $10 and I had to do something. This worked like a charm. God bless you man.
All I ask is that you know your limits, know when it's time to call a pro, and you must accept complete responsibility for your actions.
@@uxwbill fair enough
Welcome back uxwbill hope your thanksgiving was good. And welcome back Furhead.
It's been a long time since I've watched you but I'm glad you're still around
Always love a UX video! Also enjoyed hearing you watch a certain antiDIYHVAC channel I also watch! Good to see an upload!
This was the perfect thing to watch while waiting for my flight at PIA at 5:30 in the morning.
Great video bill I’m glad to see you helping that church out the Lord God will bless you for that merry Christmas to you and your family glad to see you back on UA-cam
I don't have this issue but your video was in my recommended, its very interesting and entertaining to me.
Nice hear your voice and comment on stuff thanks for posting again we missed you always interesting post you do !!!!
Very nice video.
Good stuff as always, Bill!
Also, love how you and Furhead just randomly broke out in Manah Manah towards the end, lol
"Manometer Manometer" was Furhead's idea, and what a great idea it was! We actually had a trio going on, with myself, the Keykeeper and Furhead. The camera would have benefitted from a wider angle lens...
Edit: I'm thrilled that someone noticed! (What people comment on in my videos is almost always not what I'd expect.)
The Legend returns.
A plastic bag sitting on top of a furnace does not seem like a good idea...
I presume you're referring to the bag in which the furnace manuals were placed? I don't disagree. I couldn't find a better place to put it with the consideration that the mice would probably get into it.
Well I'll be dipped
Dipped in what? :-P
That device on the incoming gas line is there to prevent the furnace from firing if the tank runs low or regulator gets messed up and supplies far too low incoming pressure. It prevents the furnace from sooting.
Though I have no direct experience with propane, i've seen more than one youtube video showing totally rusted up/trashed inshot burners when used with the fuel. It must be harder on furnaces/more corrosive than natural gas and it could be wise to pull and inspect/clean.
As always a very enjoyable video thanks
Glad see everyone doing well.
HEEES BACKKKK!!!!
That switch is actually extremely common on german boilers, and its purpose is to stop large premix gas burners (gas and air are mixed in one or more seperate chamber(s) before entering the burner) from backfiring and thus damaging the mixing cup/chamber. I had a ton of odd problems caused by that switch, like trying to do a dry run on a freshly changed control, only to have the switch cut power to the boiler because the gas tap to the burner was still closed. It can take you half an hour of trying to find out why the control panel won't start up, only to eventually find out the thing needs gas pressure to even turn on... As for the mouse stink, I think there is a dead mouse somewhere in the ductwork. Also, "dead mouse" is sadly one of the most common smells a HVAC tech will experience, and one should absolutely know that before starting in this field.
There is no doubt in my mind that dead mice are present in the ductwork.
Good content as ALWAYS :)
Ferris Wheel From Hell - that’s great! Y’all never cease to entertain me!
It's based on reality -- that's what I said to a little old lady after I found out why her furnace sounded like a train...the blower wheel finally spat the mouse out, probably as it came to a stop.
Hi Bill, hope you're well!
I'm tired and irritable, so about perfect. :-P
I've heard from manufacturers that using sand paper can remove the coating on the flame rod and cause it to fail. Now if that only pertains to some flame rods or if it's all of them but I've always been taught to use a green scotch bright dish washing pad because it gets it clean but it's not too abrasive to the point where it removes metal from the rod. Just something I've been told and figured it share it. 🤷♂️
I would keep a eye on it with mice u never know what they get in to the fact u found a dead one might be a sign good video
And yes like other people have commented like to see a variety of videos and Merry Christmas to you and your family
My house has had the same HVAC system since 1996 and the igniter stopped working in 2017 and we know someone that does HVAC work and it's been working without issues since then. I usually inspect the heater every September for any chewed wires, strong mice odor, the filters, gas leaks, and so on.
Granted, I'm not a professional HVAC person.
Professional or not, if you take care of your HVAC system, it'll take care of you for a long, long time. More people should do what you do. Even a quick test done before the heating or cooling season starts is a good idea.
God to see you bill, how's your mom doing? What's the keykeeper and fur head been up to?
First. Do do do do manometer!
@ymxctrails You'll know what it is, if you watch the whole video...
Why hello there uxwbill. I'd have watched your video last night but it looks like you uploaded right after I went to bed
I love your videos. They are so pragmatic! How's the 07 Classic Silverado holding up?
I still drive it every day. Rust is fast eating the rockers and it's got a foothold on the bed sides above the wheel wells. A sensor in the passenger's side door latch failed, causing the truck to have a crazy fit about whether or not the door was open while going down the road. I made some effort to try and clean the contacts, which didn't work, so I just unplugged that part of it. The power lock actuator is wired separately and it still works. I would replace it, but Naughty Truck apparently came equipped with the most expensive part of several that were used...and at some point I should probably invest in an air bag sensor.
I did send the instrument cluster off recently to have it totally rebuilt and a trans temp gauge added. It came back looking and working better than it ever has!
I'm sticking with it. There's just about nothing on the market today that I'd buy new (a Chevy fullsize van being *the* possible exception). I don't want to be driving something that feels like a video game, will not tolerate any sort of touch screen, nor do I want the first electronic nanny.
@@uxwbill Good deal! I remember the video's when you first got it! That is one of the last true quality built GM trucks on the road. I have a 2006 GMC Yukon 4x4 which has been problem free - I also had a 2005 GMC Sierra truck like yours, but 2wd and I sold it to my uncle; he is very happy with it.
@ymxctrails In all honesty, I'm not sure I can be bothered to invest the effort. Naughty Truck is sitting at 220,000 miles as I write this, and I don't think it's rust that will ultimately sideline it. I also don't really have a good place to do something like that, or at least I don't think I do.
The red Reliant (actually a sedan) was very badly rusted before I got it. Amazingly, somehow the silver wagon was spared the same indignity (well, mostly), and I'd probably still have it if extended family members hadn't gotten annoyed with its presence and if I'd have had the time to give it the attention it really needed.
As the red car still ran very well, I wanted to make something or another out of it, possibly a "pole car" with a rear mounted seat. I'm nobody's idea of a metal worker, though, and there again comes the whole matter of having the time to do so or a place to keep it.
Rats are a major pain in the hatchback to deal with, but here in Florida we have more palmetto bugs than rats, no matter how many roaches you kill they still keep coming.
Not to mention that you're more likely to run into alligators and snakes.
I do agree to the fact that some people don't take safety into consideration when they do DYI fixes on their gas appliances, since 90% of the time it can and will lead into a fatal situation that involves being asphyxiated by either carbon monoxide or natural gas, or getting obliterated in an explosion.
Also some people can forget to test their CO detectors and most of the time they won't realize it's not working properly until it's too late.
Thankfully, I don't think there are any rats around this old church. The cold certainly helps keep the roaches under control, although I suppose some just go underground or just enough survive inside buildings to re-emerge during the warmer months.
The church hasn't got a carbon monoxide alarm to my knowledge, but I'm thinking of supplying one.
I did HVAC for awhile and did my fair share of intermittent heat calls, classes and work didn't prepare me for working on the dinosaur of a furnace in my new house after it developed its own intermittent heat condition. It's a Kenmore 70 Power Miser natural draft gas furnace featuring direct spark ignition, the burners themselves are quiet and burn nicely but there's more heat going out the flue than into the house and enough soot buildup in the burner box and draft hood that I suspect it's going to meet its end soon due to an unhealthy looking and sounding blower motor and plugged heat exchanger. I also observed odd flame behavior not influenced by the blower motor and a piece of insulation board held down by a brick covering a previous return cutout. among other things
There's got to be a reason it's not burning cleanly. Provided the heat exchanger is actually still good, it might be savable...might not be worth it for something that's only 60, maybe 70% efficient at best.
@@uxwbill I got a good peek inside with a borescope and the heat exchanger is coated in soot, possibly in its previous life it burned propane and they didn't clean it when they moved and converted it. It's getting replaced soon with a good used 90% furnace and matching 5-ton air conditioner. I got a good deal on them as the air conditioner still worked and had its full factory charge when it was replaced by an inverter heat pump and the 90% furnace wasn't that old either when it was replaced by a 96% furnace for no reason other than slightly higher efficiency and a tax rebate.
very much enjoyed the video are you doing more hvac for work or just volunteer and personal no need to answer if you don’t want im just curious i would also hire you if you were in my home state and close by i love how you do your work and your honesty so anytime i would need service it would definitely be a privilege anyway hope you and your family had a good thanksgiving and a happy new year upcoming i look forward to your next video
I'm not sure how detailed of an answer you want, but as brevity is not my strong suit...
The HVAC stuff is something I'm doing on the side. I don't promote or advertise for it. My day job is in IT and keeps me more than busy enough. This particular job was a volunteer effort, not that I care. One should ideally use their skills to stay in practice.
I'm pretty strictly focused on servicing existing residential and air circulation based heating or cooling systems. Although I trained for commercial/refrigeration stuff, I've not done more than a handful of those jobs. Boilers came up in my classes, and we got to see several from many different generations in commercial settings, but none were residential and we were limited in what faults we could simulate and solve. There's a lot about hydronic systems I don't know.
HVAC/R installation doesn't hold a great deal of interest for me and I don't really have any sheet metal tools. (That said, I have done some changeouts of condensing units.) I'm terrified of heights and really don't want to get up on rooftops. (I'd be fine once I'm there, as long as it's not near an edge or any kind of pitched roof. It's just getting there that's the problem, especially on extension ladders.)
I carry insurance, have my EPA 608 universal and 609 MVAC (automotive), but the latter is basically for my own unroadworthy wrecks and their A/C systems. I have no intention of doing MVAC for hire.
Flame sensors can be tested with your multi-meter set to uADC. Should have at least 1 micro amp DC. Usually around 2.5-7 depending on manufacturer.
That was to be shown in the video, and I forgot. The meter might have made a few cameos in the background.
LP gas does it take tole on Furnace Burners and heat Exchangers that what i learned but anyway great video bill i do hope they let you service it in future getting costumer one at time is all ways good
Epic
That reminds me of a time when a raccoon died in the shed, way in the corner where the roof corners meet, past the wall. I had to break out the rubber gloves and get my face a lot closer to the dead critter than I had hoped in order to remove it. I hope to not have to replicate that experience.
you want me to read the whole vid description?! …THAT's half an essay!
Okay, then don't. Just don't ask questions that are answered there. :-)
is it true new furnaces dont last as long as old furnaces
If they are LP they don't
The only thing that can be said for sure is that the new furnaces are lighter as compared to the old ones. They're also far more efficient.
Many of the furnaces sold today come with a lifetime warranty on the heat exchanger, so you can't say the manufacturers aren't confident. (Although, if you are a pessimist, you could say that the manufacturers are banking on someone forgetting about this, or saying "hey, I got my money's worth out of that".)
@@uxwbill they're banking on people not doing it due to the labor costs and other parts being out of warranty. beyond 15 years i don't think heat exchanger replacement is worth it most of the time, and definitely it's pretty crazy after 20 years unless it's a tech doing their own.
@@uxwbill From my experience older furnaces do last longer with maintenance, the 1992 Miller mobile home furnace in my second house had no maintenance whatsoever done so it was sent to scrap because of a failed heat exchanger among other things, the also 1992 Trane XE78 in my first house works fine even after being moved pending demolition of said house, the likely 1980s vintage Kenmore 70 Power Miser natural draft direct spark ignition furnace, the aforementioned furnaces being induced draft and using hot surface ignition, in the house I'm hoping to buy soon enough still works like new and for better or worse blows noticeably hotter than the induced draft furnaces even with the blower on its highest speed tap, the new Goodman furnace that replaced the Miller is so far trouble free but it's not even a year old, at the same time I have my assumptions as to what will fail first but only time will tell.
I was watching your old 2001 buick video..do you know how to jumpstart the 2001 buick century?
I really don't have anything to offer beyond suggesting that basic jump starting instructions will be readily available elsewhere online. Even if the battery is somewhere stupid like under the seat, the same basic principles still apply. You may have to get creative with hooking up the ground, or just throw caution to the wind and connect that at the point of the battery.
i found the problem, its a goodman :P
Dead mouse? Bring it on.
I try to be respectful of my viewers, hence the warning.
FOURTH! WHOO!
So you have worked on a lot of furnaces, or enough furnaces, have you ever seen a Coleman furnace? Cause that’s what I got at my place and I just wonder if you have seen one.
I'm still very much starting out in this field. There are plenty of things I don't know about or have never seen. I'll go further and say I don't think it's possible to ever know everything in this line of work.
Coleman equipment is often seen in mobile home/trailer home installations and they are one of the few manufacturers catering to that market. I've not personally worked on a Coleman HVAC product, but I've seen several of them along with the closely related Evcon brand.
Everyone sing the Manometer! :P
I have to do this at least every other year. works everytime on my 20 year old furnace.
You might want to find out why that's happening. While probably not overly serious, having to clean the flame sensor that often is likely to indicate another problem.
@@uxwbill I asked my furnace man why and he said cause it was old and they get crusty inside but only said to consider getting a new one, nothing about having it cleaned so I assume they can not be cleaned internally? I also have had to oil flu fan the last few years on this 25 year old natural gas furnace. All three burners output a strong blue flame so not too worried. Just saw another video saying a dirty flame sensor is number one furnace problem.
Like my car, I just keep her going, as I will be applying for antique license plates this year on its 20th anniversary.
Years ago I tried to buy that sensor from an appliance parts store and they wouldn’t sell me one.. and told me not to clean the original. Said it will damage it. Lol I ordered one from Amazon and cleaned and put the old original back in.. 5 years ago.. it’s still working ! Thinking of furnaces , do you know where I could get a 12v timed relay for an RV furnace ?
Parts and supply houses are all over the map with regard to who they'll do business with. Most do seem to share the view that they won't sell safety critical or possibly dangerous parts to just anyone. Where I could see that making sense with something like a gas valve, I don't see things being the same with a flame sensing rod.
You can certainly clean the typical flame sensing rod and put it back into service. I suppose that if done frequently enough it might eventually wear down to the point where it wouldn't work properly/at all, but if you have to do it that often, you're fixing the symptom and not the problem.
I don't know where to recommend you look for that relay. An electronic components dealer like Mouser or Digi-Key would likely have something. If there's any possible safety related aspect, I'd definitely ask the maker of the furnace if they are still around. (I would not recommend buying any relay or circuit whose safety and quality are unknown, in spite of such things being available from numerous, usually overseas, sellers on places like eBay.)
@@uxwbill Thank you for the info
Family vehicle update??
We have that same Goodman
Really not much to say, nor the time to say it.
I think Goodman makes a decent product, though they're not very restrictive in selling them, and that can lead to some trouble down the road.
Goodman should change their name to badman
sadly they used to be good Only good brands now is Trane /American Standerd and ICP but York and goodman are chapest and poorest made
I'm not sure why. The products they offer are just fine, and would definitely be on my list of choices if and when the time comes.
@@uxwbill With Goodman they're good 5-year furnaces, thought that may have changed with their merger with Daikin, the older Goodman furnaces I've worked on usually have pretty major issues after 5 years while Trane and ICP furnaces can last much longer though the complexity of 95-96% efficiency furnaces makes it a mixed bag among all brands, give me an 80% AFUE any day and I'll be happy as a clam
@@vacexpert2020 they have the same mechanical/electrical stuff to break if you're comparing the same feature class -> ie single stage to single stage. the myth that condensing furnaces are far more complex won't die. just need to make sure the venting and condensate lines are done right, check the trap and lines once a year, make sure the secondary hxt is being kept clean by the filter.
the stuff with constant airflow variable speed motor is definitely more complex and expensive to fix, available in 80% and 90%+
Upon seeing the title, I know there's a guy who works at the same HVAC/R company I presently work for who would say "well, the problem is that it's a Goodman". Apparently, he's always had issues with Goodman equipment at the company he came from.
I'm more of the impression, as someone once said to me, that "nothing runs you over like a Trane". :-P
@@uxwbill I'm using that next time we get a changeout call on one of those 🤣
Does anybody in your area use forced air oil furnaces? That's basically all we have in my area of Canada as we have no gas service, interesting to see how they work and that draft inducer motor has a cool startup noise
I've not seen a working oil heat system of any kind around here in years. They used to be much more common. (One of my aunts lived in a house heated by a forced air oil furnace. My parents' home was also heated by a forced air oil furnace at some point, though it was long gone by the time they moved in. I also found the remnants of an oil burner in a house while replacing the gas valve in the furnace.)
@@uxwbill Natural gas and Propane are so common in the Midwest that there's no need for oil burners, they're most common up north whether it be Canada or New England
Only oil burners I've seen have been waste oil shop heaters, put used motor oil, cooking oil, etc. in them and they'll run just fine
we have that same therm in our house lol
Be glad you're in Illinois, out in Arizona you'd need a respirator to avoid the Hantavirus.
That probably wouldn't be a bad idea here either!
@@uxwbill True, just to be safe! Glad you're still kicking! :-)
0:02 LOL: Warning lol
A Testo 350 to check Combustion under 50ppm CO level. To be safe to use.
As much as I'd like to own a combustion analyzer, I can't really justify the expenditure.
That said, I don't think I'll be buying any more Testo products. I have their 550 digital manifold and while it's great, they recently disabled the old Testo Refrigeration application, probably to force use of the newer Testo Smart software. Testo Smart is so slow as to be unusable on a first-gen iPhone SE and it's even draggy on an iPad mini 5.
Not the dead mouse!
With the mouse, I'd probably have just vacuumed it up too and been sure to change the bag immediately after the cleaning was done.
I thought about and then thought better of it. Knowing my luck, it would have clogged the hose and that's one clog in particular I wouldn't want to clear.
It's strange -- with stuff like this I'm fine for a few minutes before an overwhelming urge to hurl strikes.
@@uxwbill I'm with you there! I may not have used the old SuperJ to pick the mouse up, but definitely would with my service vacuum I always have. Its the sort of thing I also have to deal with quickly, so it doesn't start making me feel sick!
Ah, yes. NB4 the video goes public. Woohoo!
Thanks for dropping by and leaving a comment! The search is still going on for the GM "H" body service manuals...
Dead mouse? Ha! Our li'l Jenny's been dispatching mice for months now... She's a regular consumptive animal technology solution...
Although I like cats, I don't know that the entire congregation would share that view and it probably doesn't make sense to keep one in a building that's used 1/7th of the week for a few hours at most. All the mouse poison stations would have to go as well, so kitty wouldn't get sick or worse.
First!
Having to burn gas for heat, how strange. I heat by pumping 190 F water out of the ground and running it through a heat ex changer.
Some people around here do that as well.
Lol
I trap mice in my garage. No problem.
I AM A BLACK MAN!
your son is great on the nuggets 💯
Typical General Motors Piece Of Crap! lol
