I know it’s an older clip..but I had a unit similar..guy didn’t seem to want to attempt a repair..I thought he was just being a arse..but watching your vids,I understand more about the unit and age..it gets to a point where you have to draw a line …. I got mine running on my own..lasted about a month, then I had to replace it anyhow….actually hauled from NC to FL and gave it to our local tech center so they could use it as a teaching tool ..we don’t have heat exchangers here..my son was enrolled in HVAC..works in the field now..
That's why you gotta LOVE a roll out switch. They may be a pain, but you don't die when they do their job. That old unit is gonna be HEAVY. The Home owner is in for a treat when they get the estimate for replacement. Great job on the diagnosis. 🇺🇸😎 (edit) the lost voltage is getting sucked into that thermal resistor on the insulation plate you removed. I guess it was doing its job also.
You're saying the voltage drop to the valve was due to the resistor that was under the insulation sitting above the gas valve? Please explain why it would do that on a cold start up. Thanks
@@kaptaintrips sure. Some (not all) of those resistors are a 1 time trip. When they reach the temperature they are designed for, they will open to cause the gas valve to close. Some of them are designed to allow the insulation ( ceramic part ) to degrade and cause a " leaching" of voltage. This type is now more common on an electric strip heat unit, ( commonly in mobile homes ) they are Very effective but just like anything electrical they often fail. But the short answer is that they degrade and only allow a fraction of the total voltage to pass.
I learned something new. How to diagnose a faulty heat exchanger by watching the dancing flames when blower kicks on. Saves over a combustion analysis.
Raymond Pajeda , a cracked heat exchanger doesn't always cause the flame to dance. Sometimes the crack is really small and only opens when the unit has been running for a long time. Those are the one's that are HARD to diagnose.
Happy new year Ted. We can’t be sure what 2022 will bring but we know there will be an endless supply of run cap banditry and helicopters to keep you busy. Love the videos as always!
I ran across a Trane gas pack from 2005 that was going out on roll out earlier this winter. The guys son had rigged it up to run. The flames would literally blow out of the front of the burners when the blower came on. Luckily the guy let me replace it. There was a huge hole in the heat exchanger. I love your videos btw.
We don't have many residential package units in Indiana.. package units are mainly commercial here. With the way that inducer motor sounded.... why didn't you check voltage at pressure switch? Seems to me like pressure switch might of been closing and opening causing irregular voltage to valve. Why not in the jumper diagnostic just jumper pressure switch and see if valve opens and ignites? Main thing is all technicians have a different way and you done good. Good job and happy new years.
Did anyone else hear The Prices Right losers’ music when the date was found? 02:52 I highly recommend for the homeowner to bid 1 dollar, when they receive the estimate.
Hope they have money saved up for a new unit, it won't be cheap. I had my 1977 furnace replaced last year and had saved up money to replace it. I bet the new one will not last 40+ years.
It depends on the location and severity of the breaches. If there are holes that are 90 degrees offset of the airstream, a venturi effect can create a low pressure condition that will draw exhaust out of the heat exchanger and into the home air supply. This still doesn't guarantee that CO will be present in the home, as a proper burn should also result in little to no CO production.
Thought thata why he went in ... would love too see the heat exch rot 15yrs gota suck for gaspack ..here in phx az was workin on 50+yr old units sometimes .. and with the newer ones its mostly comp or bad coil leaks that get them changed out .. sir have you ever seen a indoor coil dissolve from so much cat pee .. turns the alum fins into green dust and then the copper coils turn into fish bubbler stones leaks so fun then you have to tell them there ac isnt warrenteed for that abuse ?? Twice for me
Nice video. Ya, those flames were everywhere. Im curious... did you measure voltage output at the transformer to see if it was wavering there also,or if it's a board/wiring issue?
I own a property with 3 health aire high temps that are about 50 years+ probably if maintained would get another 50 honestly I've only replaced a pully some bearings and rewired a motor because the cable was dry rotted........... I really don't like the newer stuff
Ok so you hooked the jumpers up to common and red(24v) right? Where is the white jumper a little further into the video? It's just over the insulation or where?
Vent port can allow rain or condensation to fill the atmospheric side with water and prevent the regulator from doing its job, even worse in freezing weather where ice can form and lock the regulator in a "wide open" condition. Gas valve damage can happen very easily happen in that situation.
Erratic voyage he saw suggests cracked solder joints on the board socket for the molex plug. I've repaired many control boards that had cracked joints rather than replace the board. Saves me time, the company money, and the customer feels we care that much more about getting things done fast
It was nice meeting you Mr. Cook at Best Buy. It was a pleasure shaking hands. Again Thank you!
Yes !! I really appreciate you saying hello !! Small world !!

Nice job Ted, you can certainly hear the difference too. Time to send it down the road. Happy New Year, stay well.

Buy a good manometer, that’ll tell ya fer sure if you have a heat exchanger issue
Happy new year Ted. We can’t be sure what 2022 will bring but we know there will be an endless supply of run cap banditry and helicopters to keep you busy. Love the videos as always!
Never heard of a gas pack until I moved down south. Appreciate the videos and Happy New Year.
We had what looks like the same unint 22 years. We had to replace it 2 weeks ago. Heat exchanger had the same problem. It was time
I ran across a Trane gas pack from 2005 that was going out on roll out earlier this winter. The guys son had rigged it up to run. The flames would literally blow out of the front of the burners when the blower came on. Luckily the guy let me replace it. There was a huge hole in the heat exchanger. I love your videos btw.

If pressure switch does not close, I don't think igniter will spark at all.
Well happy New years hope you had a Merry Christmas how do you like the weather here last night in the upstate LOL

Hello from the great state of Michigan. Happy new year Ted
I think My Parents had a Trane like that one and it jumped the track about a year ago. Pretty much the same problem.
Just out coriusity why you ware not getting 24 volts to the valve? What's caused that ?
Happy New Year. Thank You for your great content. Old School !!
Happy New Year, Cowboy 2022 !
Replacement time. Thanks for the video
Hope they have money saved up for a new unit, it won't be cheap. I had my 1977 furnace replaced last year and had saved up money to replace it. I bet the new one will not last 40+ years.
I believe the camera picks up the meter display better without the backlight
Another great job ted
UNCLE TED!, IT HAS BEEN A YEAR!!!!!!!!!! 😆 😅 😂 🤣
A package and a split on the same house. That's an unusual site.
Happy new year Ted thanks for all the great 👍 videos keep them coming
Nice troubleshooting sir thank you and happy new year.
Do they all sit on ground like that where all the moisture gets to them. Is it possible to install them up off ground or is that not normal?
Good one Ted.
Great video. Keep’em coming.
The pressure from the blower is blowing into the heat exchanger. You won’t read any CO at the grills while the unit is running.
You will the same way a caborator works. It'll exchange gasses from the exchanger and put them in the house.
It depends on the location and severity of the breaches. If there are holes that are 90 degrees offset of the airstream, a venturi effect can create a low pressure condition that will draw exhaust out of the heat exchanger and into the home air supply. This still doesn't guarantee that CO will be present in the home, as a proper burn should also result in little to no CO production.
Testo read 4ppm on a supply vent.
You knew exactly how to get him to answer lol
Did you manage to get any CO inside?
Thought thata why he went in ... would love too see the heat exch rot 15yrs gota suck for gaspack ..here in phx az was workin on 50+yr old units sometimes .. and with the newer ones its mostly comp or bad coil leaks that get them changed out .. sir have you ever seen a indoor coil dissolve from so much cat pee .. turns the alum fins into green dust and then the copper coils turn into fish bubbler stones leaks so fun then you have to tell them there ac isnt warrenteed for that abuse ?? Twice for me
4ppm he said in another reply
Here's to hoping you had New Years Day off!
My furnace is a 1974 gas. These new ones are junk. They will kill you with CRACKED heat exchangers.
Oddly enough, the newer heat exchangers are less likely to crack...
people thinking they will get 5-10 more years on a 20 year old units. I roll my eyes and say NoPE. Be happy it last 6 months
So did you get the unit running for them or did you just condemn it because of the heat exchanger problem
did u get any readings inside never good when the HE goes bad that will kill ya if u dont have a co2 detector and i got 2 running in my house
Happy New Year and thanks again
Not so sure how id feel about having something that burns flames so close to grass/leaves etc
Happy New Year!
Happy New year Ted 🎇
Nice video. Ya, those flames were everywhere. Im curious... did you measure voltage output at the transformer to see if it was wavering there also,or if it's a board/wiring issue?
Im a service tech yeah check transformer first main source of power
Fellas he was obviously running it from the transformer with the jumper wire. So if there was a transformer problem. It still would of existed….✌️
Exactly.
I own a property with 3 health aire high temps that are about 50 years+ probably if maintained would get another 50 honestly I've only replaced a pully some bearings and rewired a motor because the cable was dry rotted........... I really don't like the newer stuff
So were those flames doing the two step, was that a jig, or was it more like a waltz? #theyaredancing #shesbad #RIP
😎👍😎👍😎👍
More like the twist.
First one 💪🏿 hell yes. Happy New year Ted.
That thing looks like it has been bad a long time. I see black in the burner compartment on the inside walks.
$$$$ 😢
Ok so you hooked the jumpers up to common and red(24v) right? Where is the white jumper a little further into the video? It's just over the insulation or where?
He left the common terminal connected to the gas valve and just used a jumper to connect 24V hot to the valve.
@@wkenealey oh I see it now. Hes grabbing 24v off the hi limit!
Happy new year Ted
Teds excellent adventure
Good vid Ted ... Thx for sharing ...
Good job Ted, I think that Trane has had better days, haha, rest in peace to another Trane.
Happy New Year's
"she's dead Jim"
Happy New year
So what was decided?
Everyone in the house was nearly brain dead from long term CO exposure and moved to Denver before paying the bill.
I think I see a tiny hole in the middle hole.
It's a trouble Ted run for the Hills
That package unit needs to be replaced
That thing was ready for trash heap.
Scrap yard, anyone? Replace with a nice split.
Does anyone know why the regulator should be upside down?
Vent port can allow rain or condensation to fill the atmospheric side with water and prevent the regulator from doing its job, even worse in freezing weather where ice can form and lock the regulator in a "wide open" condition. Gas valve damage can happen very easily happen in that situation.
He said so if you listen closely rather than ask...
She’s a leaker mama
It's a has been. It's seen it's day
No flame= external lock out I guess
Erratic voyage he saw suggests cracked solder joints on the board socket for the molex plug. I've repaired many control boards that had cracked joints rather than replace the board. Saves me time, the company money, and the customer feels we care that much more about getting things done fast
👍
time 4 new
That unit seen better days.
Thanks again for the videos.
