Hop this helped those learning
So jobber has really helped you ? I’d love to do this
@@P9rkour90 yes 100%, very easy to use and great support on the product
A friendly suggestion is to pull that heat exchanger door below the blower. I have found about 12 in the past year with the infamous carrier crack where the tubes have been pressed in place.
Not a giant safety issue but shouldn’t go left un checked
Yes, that was done
Those model carriers are so common , I often see the heat exchanger plate where the inducer motor and burners mount on absolutely rusted. And the doors always bent with tappers everywhere lol
Dude what a helpful vid this is, i would have spent hours and might not have figured out why the flame was rolling out.
Great Video Gary.
Thanks brother
I love this video channel. Makes me miss my service in the field
I appreciate that!
Good catch Gary. Well done! Keep it up brother.
Thanks James
More videos like this man. They help a lot !
I'll do my best
Super helpful. Thank you Gary.
Cheers
Slow Rolling draft motor. Changed my diagnosis about 5 seconds later considering the amperage draw on the motor
Good choice!
Yes your videos help a lot Gary. I hope you are doing well.
I appreciate that, doing well here. I hope the same for yourself
Still remember my very first service call alone , had the exact same problem. New lennox tripping on roll out . Gas pressure was never set and ventor was on it's way out
Dear Sir,
I like you're all descution . and also andrusteand well . because you're english verey simple .anyone cen learn from you. Thenks
Quality content. Congratulations
Cheers
Nice catch with the amp draw.
Thank you!
Great job man!
When is a furnace old enough that you cant recommend using it any longer?
Great video. Thank you
You're welcome
Awesome video I learned something
Glad to help
Nice!!! Good job
Thx primo content
It's clearly the combustion fan motor, why do you recommend replacing the gas valve, In my opinion, the gas valve is working and there is no need to replace it. thanks for sharing your videos.
Because the gas pressure can't be adjusted.
As I mentioned the gas pressure is high, the caps to adjust are seized and stripped.
Nice video
Did it work well after changing the gas valve and Inducer motor???
Did you get video on diagnosing this rtu?
This video was diagnosing the RTU
Hey we put it American standard 3 ton propane gas pack residential unit at a house in 2019 that was early spring. We went back out there in the fall of 2020 and found the rollout tripped and found the inducer motor was covered in Suet. Gas pressure was at 10.5. Talk to the tech support of Team Air and had a technician come out we reduced the gas pressure to 9. Check to make sure they gave us the right LP kit and replace the regulator. After a week it did it again so we swapped the whole unit for a brand new one. Went back out there this past week and it’s doing the exact same thing and the inducer motor and heat exchanger was clogged. Could you please help me with this call. Any information would be great from all technicians. I went out there Wednesday and replace the inducer motor and heat exchanger. Now I’m just waiting for it to do that again.
Has anyone put a combustion analyzer on it. Start there.
Does the lp furnace have a low gas pressure safety shutoff? Silly question I know but you could be dropping pressure.
@@jaymz0074 I'm with you brother. Running the furnace till tank is empty will kill the unit without a low gas pressure safety
Hey, great video. When you say you sub-contract, you bill the contractor or the business?
Yes correct!
My first guess at 4 minutes and 43 seconds is broken blades on the inducer fan wheel.
Gas valve caps are seized and stripped ? By another tech or was it built like that?
Stripped by another tech, seized due to corrosion
So, is the roll-out sensor , shutting the unit down ??
Or do roof-top units not have them??
Rooftops have them, the gas off when I got there, so I don't know if it went off on roll out prior
Any fuel fired unit, ducted or not, has at least one roll out switch in the burner section, not uncommon to even have 2.

Thanks for that.......I don't think I fully understand why the flame rolled back, if the exhaust duct isn't clogged
👍
Always love the thumbs up!
Mine did this and lit the unit on fire. Melted all the wires.
Opening part of the video gas valves off
? The flame is rolling out, the gas valve is not off
I had a 70% furnace burn my mustache off I was up close at the burners and soon as that blower came out a ball of fire shot out at my face as we was demoing it we came across a massive hole in the heat exchanger
The reason why is just the fact that it is a CARRIER lol
Great video Gary.
Thank you!
