You need a "NO STEP" sign on that gas line. Now you know why they add an extra 10 feet of wire to each device. Nice to have a welder handy. You done good.
That looks just like the one I got called on 10 years ago. The "head engineer" of the hotel jumped out all the safety controls. Heat exchanger was toast you could see through it not like it was a small crack or anything. First time I ever got out my side cutters and basically stripped the unit on the spot to make sure he didn't kill someone. This was for a conference room they had 500 people booked for
Sounds like the rent house we moved into in 2006. The only thing I asked of the landlord was to have the heating fixed before we moved in. I went up in the attic, and I could see through the side of the unit, the cracks were so bad. (and I'm an IT guy. I just spent years growing up in a 'if you can fix it, do it. It's cheaper, and you know what the idiot actually did to repair it.' family.)
@@adammalzahn7238 - You can, but unfortunately we're forced to make everything 'too safe'. Used to be the person making the mistake was the first casualty. Now they have time to get away.
Great job, Rick! Nice to have the ability to weld that. We had a rooftop gas unit that had caught on fire once. It was on a zone system (zone control panel was bad). Apparently the unit was tripping out on high limit, so someone (not us) decided the fix was to remove the limit switch. Then the VFD failed, blower was not running, and Everything melted.
I have bypassed safeties in the past. Supposed to be temporary. Quote sent to customer. They refused. Said it was heating fine. So I no longer jump safeties for customers. Just not worth the liability.
Man, the stuff you run across. Nice adopt and overcome with a little help from your welder. The customer probably has little idea how fortunate they are.
You likely correct, if I were able to show and convey how different things are done in my part of the country it might make more sense to some viewers but it’s all about perspective. Thanks for the support Jay 🤜🤛👍👍
Well, that one scares one to death. Nice work. I always enjoy the thoroughness, not stopping at the single problem that brought you there, but recertifying the entire systems.
From what I'm hearing they parts aren't there. Were waiting on carrier infinity stats, controls, and other parts. It would have likely taken a min of 2-3 weeks. I like to fix stuff, it's the farm life sneaking in lol
@@HVACRSurvival I agree with you and your way of thinking and fixing things is exactly the farmers way and that's how I was raised and I do the same thing if I can make a small weld to keep them with heat I keep a wire welder 120 volt on my van so small things are no problem if they still need a new exchanger or manifold I'll replace it when the new one comes in
In the alarm section when the alarms are displayed like”T155” you can presss escape and enter together simultaneously and it will read out the alarms! And also can do the same thing to read out abbreviations! Happy HVACING
I was a number at my company too, 1 of 35 service tech's, or 1 of 450 represented by union. Had steam fitters, plumbers, electricians, sprinkler fitters, controls, sheet metal, refer fitters and service techs. Came in handy when in situations like you were in.
Nice thing it was a shop to weld it quickly. Good thing you spotted that? Something must have hit it and to much pressure as weight all on pipe. That wiring toast it would have all came out and redone. Shocked they put a resettable cutout on it? Nice to have the gas going actually going though burners to exchanger instead of compartment.
All of years I did this not once did I see anyone use a auto rest roll out switch like you said that’s stupid but Carrier never failed to surprise me on their equipment.
If maintenance wouldn't have been resetting it over and over it wouldn't have been as bad but that's why you don't rely on the electronic control board to shut it down.
Nice job Rick! The ignition control module should lock out the heat with the roll out, carrier does all their units that way, reset the power it will try again.
@@HVACRSurvival I got that from the video but if your resetting any problem it's just gonna try again, only manual resets are on resi furnace right? Most commercial is all auto reset roll out.... or am I wrong 🤔
I was glad you were able to unscrew the broken part out of the gas valve, and it didn't screw up the threads on the gas valve. Could have been a lot worse, like gas valve, inducer motor, and all the wiring burned up...and then the customer would have a bill several times higher. As far as something like this happening to me, I had a small package unit that the control board caught on fire, (looked like started from the main blower motor relay), and that spread and toasted a lot of the wiring. Ended up replacing a lot of the wiring like you did, along with a new control board, new 24v transformer, and compressor contactor. I'll post a couple pics on my channel.
I miss doing rooftops ha ha, I do the same thing I look at everything I can I put my hands on stuff I look for all those items you checked off on the box that’s how you pay attention to this stuff and somebody has to do it at least once or twice a year just to make sure shits not going south, excellent
I work on swimming pools. Pool heater rollout sensor is not resetting. Once it's toasted, it needs to be replaced after the rollout condition is fixed.
What are you talking about? If you're insinuating that that's not really our shop then where is it, I have better things to do to try to fool people about a repair.
@@HVACRSurvival Just an advice. What I mean is the two clips of the shot were combined BEFORE you slowed it down, which meant the editing program you were using tried to smooth out the cut and resulted in a few frames of gibberish. Slow the clips separately before you stitch them to avoid this :3
Interesting comment on the high tension lead as it's laying on the cabinet. Which is ground also. I like to use non-insulated solderless connectors as I get a good look at the crimp as it's made. Course you then have to insulate it with some heat shrink. Get-R-Done!👍👍
Definitely agree should have a manual reset roll out so that way a competent HVAC tech would be called out and see what's going on before resetting the roll out
I’m not a hater I thought that was a good video, I just cringe at the thought of hand spinning a nut or fitting that some amateur previously grabbed with a knipex it’ll cut your a.. up! that’s not hate We just don’t always wear gloves
Would those flames have ever even reached the rollout switch? (Even judging by the burnt wires, I'm not convinced it would have.) Given the size of that burner assembly, I'm surprised they didn't use two. Edit: I'd be curious if it faulted out on failure to prove flame rather than rollout/limit...and to answer the question, no I've never seen this. Hopefully it wasn't a result of someone being up there and starting to fall...
I think with the door on the flame caused the burners to flash back over and over. The way the wires were burnt on both sides is what leads me to that thought.
I hate butt connectors myself but i use them at times (my preference,not putting you down). When i put wires into connectors, i bend the exposed wire into a "U" shape so you are getting more wire to pinch for a better pinch hold and electrical connection. When the wire is small enough
I did a lot of research on crimp connectors, a lot of people use the pointy end to puncture the crimp connector and that usually does not result in a good crimp on an insulated connector. the second problem is they use cheap crimpers. There's actually a lot of testing behind it but most people don't care to learn. Thanks for checking it out👍👍
Would have gone with solder for the wire splices. More reliable, less prone to corrosion with relative moisture flowing through the unit when shrink tubed. Just my opinion. You do you 😊
Seemly there's enough Oil mist flying around that Air Handling Cabinet that Corrosion wouldn't be the Issue, very lucky that the Oil laden mist within the Unit carried within that duct work didn't take off, if the Belt Broke, and the filters weren't blocked then Vapour would maybe have filled the unit by Convection, ...that would have been serious, as the Triangle of Fire was there, Oxygen, Fuel and a Source of Ignition... a Virtual BOMB, Houston We Have Lift off... You CAN fight a Fire, but Not an Explosion...
Just a quick question you did not put any pipe jointing compound or gas PTFE tape on thread is that normal practice in States UK have different regulations . Nice video
11:08 Look the the gray threads then notice the gray pipe dope and then hear me say "I have it doped up". Please don't skip around in my videos because unlike most channels I cut most boring spots out and you'll miss details like this one you asked about. It takes time for me to come back and rewatch it to find these things. Not trying to be a jerk but unlike a lot of channels I try to respond to each comment that I get and not just "like the comment". Thanks for your checking out the video!
you know they make a filter box grabber for the side of the building I did it the hard way like that for 10 yrs before I found the grabber no longer 2 people on 20 boxes or 3 at a time up and down ladder.
Usually the IFB would lock it out on smaller package units if the roll out switch was tripped, not sure on that model Carrier as it has different controls.
I said it pretty quickly in the video but the maintenance department had been turning the power off and resetting the controller to get the heat to run for a little bit. Theoretically the electronics did its job but it's not a true lockout once the power is killed.
@@HVACRSurvival that's not a maintenance department I'd like. I'm in IT and so I'm well aware of the turn it off and back on fix, and will tell people to do it often, and try it with equipment in many circumstances, but that doesn't mean I'll do it endlessly, if the issue keeps coming back deeper analysis and fixing is needed, and with equipment like HVAC where it could damage the equipment or create a safety issue that threshold is not very high, after at most one or two resets they should have shut it down and left it off and called in an expert.
You did a really nice job it looks more professional when it came from the factory! Keep up the excellent work. Be careful and watch out for ovens as someone might mistake you for a turkey. Happy Thanksgiving if we don't see you before.lol
May not mean much now but do you think someone was being lazy and not using a ladder and used the gas line for a step is what that looked break looked like good video brother
I'm surprised that an auto-reset flame rollout switch is even legal. I mean, if there is a flame rollout, it mean that there is an issue that need to be fixed. It's gas and fire, there is no chance to take with that. But seeing how the regulations are all messed up (way too strict here, way too loose there) I'm not surprised.
The way the system was designed was to allow the electronic control to lock it out but they were resetting the power to it causing it to happen over and over again. That's the main issue here.
@@HVACRSurvival Still an unsafe condition IMO. And that is the proof. I mean, people always get told to turn it off and on again for basically everything. Gas appliances are basically one of the few exceptions...
3:30 You need ratchet wrench. It's strange to think that USA uses gas? in HVAC to produce heat. We mostly use heat pumps here in Finland (and maybe other Nordic countries).
There's commercial heat pumps available in rooftop units but generally they don't work with a crap when it's 0° Fahrenheit outside. Are you using inverter driven heat pumps on package units? Or are you using mini splits? If you listen to the sound after I use the adjustable crescent wrench to loosen the nuts I'm actually using a socket set. As a service technician I use all of my senses at the same time, touch, feel, smell and hear and sometimes taste. That will make you a better technician if you don't rely on only your eyes.
Nice job getting that welded. I used to work for company that had a great welder. Saved me more than once. You could have just left unit down with new burner manifold on order as many others would have done.
everything is great but as soon as you alter any manufacturer design & g forbid sometgoes south the liability is not on the last company that touched it from insurance standpoint thats why technically you’re supposed to replace it with original or updated part, & commercial space should have temporary space heaters of some sort until equipment gets resorted or replaced etc.. that is actually standard as per any commercial industrial insurance liability standards
@@ping_me1vp We do industrial high pressure piping and a lot more dangerous jobs than this low pressure gas line, were insured for all that kind of thing. Your liable soon as you touch any equipment. I know what your saying but were not some small mom and pop residential company that carries a couple million in coverage.
Something I noticed is it seems like you showed up on site and went straight to doing general preventative maintenance without actually diagnosing the customer's complaint?
I had already spoken to the maintenance manager, sorry I didn't get that on film for you and get a written letter of recommendation, I went up on the roof and found the problem within a couple minutes what exactly would you have done differently? 90% of these service calls could have been eliminated with proper maintenance. This ain't rocket science.
You're a hilarious, why don't you do a little research on what I use before you run your mouth, You're not very observant. Take a little closer look at the Jaws. amzn.to/3Br10FT
Nothing like flame shooting out at you keep saying your toes makes life interesting if I had a dollar for every time something through flames at me I'd have $2 LOL
That manifold must be made of some thin pipe. Usually the aluminum gas valve would break first. A little high temperature silicone would have got you by until a new manifold came in. Well maybe not, since no one has parts in stock.
New burners and manifold, welding that manifold you just changed the factory specs, you own that equipment for life, I think the gas codes in the USA are non existent, where I live in Ontario Canada, the TSSA would take your gas license.
Some places make more of a deal of the stupid things that don't matter than others. I would love to know how the factory welds in your gas lines in a commercial buildings....lol they don't, we have certified welders and you must not know much about Tig welding, that is not going to leak.
You’re hard to watch. For starters, you needed to look at the ignition control board for a fault. Secondly, the ignition control board will lock out the heat after 3 trips. When you’re using the scrolling marquee, you can press enter and cancel at the same time to see the alarm. This is easy stuff.
You need a "NO STEP" sign on that gas line. Now you know why they add an extra 10 feet of wire to each device. Nice to have a welder handy. You done good.
Thanks Max! Much appreciated. Thank you for watching.
I was thinking someone stood on the gas line to get a look at the condenser fans, great video Rick

Should be court action and jail time for jumping out safety switches in hotel or homes.

It's strange to think that USA uses gas? in HVAC to produce heat. We mostly use heat pumps here in Finland (and maybe other Nordic countries).
There's commercial heat pumps available in rooftop units but generally they don't work with a crap when it's 0° Fahrenheit outside. Are you using inverter driven heat pumps on package units? Or are you using mini splits? If you listen to the sound after I use the adjustable crescent wrench to loosen the nuts I'm actually using a socket set. As a service technician I use all of my senses at the same time, touch, feel, smell and hear and sometimes taste. That will make you a better technician if you don't rely on only your eyes.
Nice job getting that welded. I used to work for company that had a great welder. Saved me more than once. You could have just left unit down with new burner manifold on order as many others would have done.
From what I'm hearing we may not have been able to get it anytime soon. That's always in the back of my mind
everything is great but as soon as you alter any manufacturer design & g forbid sometgoes south the liability is not on the last company that touched it from insurance standpoint thats why technically you’re supposed to replace it with original or updated part, & commercial space should have temporary space heaters of some sort until equipment gets resorted or replaced etc.. that is actually standard as per any commercial industrial insurance liability standards
@@ping_me1vp We do industrial high pressure piping and a lot more dangerous jobs than this low pressure gas line, were insured for all that kind of thing. Your liable soon as you touch any equipment. I know what your saying but were not some small mom and pop residential company that carries a couple million in coverage.

Something I noticed is it seems like you showed up on site and went straight to doing general preventative maintenance without actually diagnosing the customer's complaint?
I had already spoken to the maintenance manager, sorry I didn't get that on film for you and get a written letter of recommendation, I went up on the roof and found the problem within a couple minutes what exactly would you have done differently? 90% of these service calls could have been eliminated with proper maintenance. This ain't rocket science.
+1 nice video bro.
well thats your problem right there
So you're the guy that I come behind and find striped bolts and using channel pliers...🤨
You're a hilarious, why don't you do a little research on what I use before you run your mouth, You're not very observant. Take a little closer look at the Jaws. amzn.to/3Br10FT
@@HVACRSurvival Just pointing out you bring a plumbers tool to a HVAC job.
👌😂
Rick get the marshmallows ready lol
🤭🤣🤣
😆
What? Just a few globs of JB Weld and that'd fix right up, n'est ce pas?
Electric tape is cheaper! LOL
I prefer flex seal😂
Hey you should have brought some sausages or marshmallows up on the roof with ya , could have cooked your lunch while troubleshooting eh .
I didn't think of that! I could a even made some French Toast ...lol
@@HVACRSurvival 😄
holy shit
Self-resetting rollout switches unfortunately are what the installers are told nowadays to put in these HVAC systems.
That was factory, it was programmed to shut down but they kept resetting the power to make it run again and again.
Having a metal shop at your disposal sure speeds up everything. Also this design just seems designed to burn. I don't get it.
You did not replace rollout with manual reset…
I never said I did, I said they should have used that style it rest to begin with.
👍
Nothing like flame shooting out at you keep saying your toes makes life interesting if I had a dollar for every time something through flames at me I'd have $2 LOL
🤣👍👍
Had one a number of years ago that blew the burner compartment cover panel 30 feet across the roof. 😮.
i mean, if it aint broke, dont fix her. if its still running it can last a bit more
You damaged the fan bearings belt is too tight.
That manifold must be made of some thin pipe. Usually the aluminum gas valve would break first.
A little high temperature silicone would have got you by until a new manifold came in. Well maybe not, since no one has parts in stock.
Or you could use some of the flex seal tape...lol
🤘🤘🤘🤘🤘🤘🤘🤘🤘🤘
New burners and manifold, welding that manifold you just changed the factory specs, you own that equipment for life, I think the gas codes in the USA are non existent, where I live in Ontario Canada, the TSSA would take your gas license.
Some places make more of a deal of the stupid things that don't matter than others. I would love to know how the factory welds in your gas lines in a commercial buildings....lol they don't, we have certified welders and you must not know much about Tig welding, that is not going to leak.
Wire nuts, weeping sadly as you do it right. So sad.
I could have just taped them lol. I have some wago but I don't like to use them for simple things.
You’re hard to watch.
For starters, you needed to look at the ignition control board for a fault.
Secondly, the ignition control board will lock out the heat after 3 trips.
When you’re using the scrolling marquee, you can press enter and cancel at the same time to see the alarm.
This is easy stuff.
Ok😳
😂flamethrower
That didn’t look clever
What part
