In 20 years, I’ve changed out two gas valves. One was a warranty issues on brand new unit, the second was my own coworker sending 460V to a 24V gas valve. This part is one of the most reliable in the entire system.
Hell yeah Bill! Nice job. I had one from carrier, brand new with flame roll out, scratching my head. Found no wheel on the combustion blower smh, must have been built on Friday lol.
Installed same unit a month ago. Spark but no ignition. Manifold pressure was .5" W.C. Not enough to lite off, hear or smell gas or light manualy with a lighter! Played with high and low pressure adjustment on gas valve and got it working. Commissioning of such unit's should always include checking/ adjustment of burner gas pressure and setting blower speeds for correct SP. Quality control is shit with most everything these days :(
Hey Bill! I used to love doing work for the pubs. It seems to be the vibe of it being a happy place. The diagnostic work on the gas valve was on point. Next summer it will be the vsd, condensing environment when the compressors stop and the evap warms up, vsd is nicely chilled, bang. Nice to see you around, take care. Kind regards, South Africa
We change out tons here in Alberta Canada. Our cold Winter is hard on units. If your inducer turns on and you have spark the only thing left is a bad gas valve or regulator if the unit has one. 9/10 times it’s a bad gas valve. Swap er out and BOOM! Fire in the hole. You’re 100% right to check the gas pressure on the outlet. If it’s 0.00 during a call for heat and it’s sparking that gas valve is toast. Good video man!
Missed the footage where you verified the gas pressure on the manifold side of the new gas valve and the combustion analysis and the leak check of the installation. All the "big picture" trade mark stuff.
hey man, just started watching your vids, you really gotta start making more! Really enjoy your approach and how you talk through your diagnosis. Make more videos! even how you do your PM's lol! always like to learn/see new tricks. what do you do mostly? Im a refer tech for resturant service, going on my 2nd year in march. great videos man! keep up the good work.
Carrier has been sending out a slew of bad parts, we have received 2 failed inducers and a failed gas valve in the last two weeks right out of the box. One of those inducers was for a 6 months old unit where the inducer fell apart.
Need to just add one step. Unless I’m mistaken on the new gas valves in my the package units. Check and make sure that the manifold adjustment screw was even set… other than that I’ve seen and have had valves that you turn the valve off and won’t turn back on, like the switch fails
20 plus years. I have changed out 3 gas valves. 1st one was a bran new Goodman Furnace I was shocked. Next one was a 750 horse power Cleaver -Brooks boiler at a Hospital they run all year around so that one was understandable . And the last one was a Lennox Rtu.
maybe all the construction work filled the gas lines with debris, something like concrete/drywall/tile dust and it chooched the valve on first start or so.
Funny how the S/D is not ran thru the board like it should be on that Carrier. Middle of the right side of the (blue colored) board. Gas valve could have been clogged with dope. Doesn't take much. Stay safe and be well Bill.
Thanks for the video! I've had the same experience.....gas valves rarely malfunction. Just a thought...it's recommended you check the supply gas pressure for proper combustion.
Those gas valves are trash. Lennox used them a bunch. When it starts sparking hit the gas valve with a screwdriver handle and it will probably fire. I've replaced a bunch of them.

Hey bro great work on the gas valve. And stay safe out there and stay curious. I love watching your “curiosity videos”.
I don't do a lot with furnaces, so nice to have some guidance on checking the gas valve
Just switched my sister’s gas valve recently. Not too common. Didn’t check outlet but made sure valve was getting power. Good diagnosis.

Good explanation on everything 👏

Dude I'm with ya there, love the dirty old abandonned places.
That was a weird one. Don't normally expect them to fail. Considering how new the unit looks, I'm betting it never worked from the factory.
Natural is usually 10.5" and propane is 13". Voltage and no ignition is usually gas valve bc a bad pressure switch would cut out voltage.
The Tom Brady comment was hilarious. Hope all is good Bill.
Another great video thanks for sharing
Good Job Bill, awesome job. Little picture, big job.
maybe all the construction work filled the gas lines with debris, something like concrete/drywall/tile dust and it chooched the valve on first start or so.
I see a lot of York predators that have the air Air shutter for the pilot, get bugs and webs inside them, flame actually burns out the shutter.
Bill upload some more videos man!
miss watching them!
Where you been dude?!?!
Nice job. Glad to have you back
Happy to see that you are back.
Are you in southeast Michigan?
This is over the border into Ohio
2 uploads in 1 week?? Hell yeah, keep em coming Bill 👍🏼
What is temperature rise??

I’ve seen a couple of dope clogged valves lately
Loved that Tom Brady comment 😂
Cool video. Like your sense of humor. 😂 👍
Was it under warranty 🤔
It was brand new unit, so yes.
Nice to see you re-appear with a new video.
Looks like the plaza is now shut down… what else did you do on that damn roof, lmao!
Shouldn’t the condensate line drain off the roof ?
interesting catch, watch out for that epa 😂
Must have had uncle Rico as a qb coach
Quality now days. 🎃

You back in the field
The Tom Brady comment made me luagh pretty good😂 keep the vids coming.
in 24 years he made a lot of mad fans
Good video 👍 buddy
Glad you’re back
The garbage that didnt know what it was could have been a make up air unit for the kitchen?
It was an abandoned many years ago, new makeup installed last summer
🤘🏈wooo
What happened to the signature beard did we have a little incident
Those gas valves are trash. Lennox used them a bunch. When it starts sparking hit the gas valve with a screwdriver handle and it will probably fire. I've replaced a bunch of them.
When you saying the fancy cap that make me laugh.there are no out door access to go up the roof what is the fancy cap for 😂.
Yeah bill I know what you mean in or where you were going with that conversation as far as the EPA goes it's a shame what they're doing
304 Thumbs uP
Nice to see u again 💪🏻
