must have schmutz/rust in the flame cross-over channels between burners or at the edge blocking it, between center and right burner or maybe lack of gas out the middle/right.
I agree. There is a high probability that there was a speck of dirt or rust in the cross-over slot. The symptom was delayed ignition with a full-sized burner flame identical to the camera image of the other two burners after it finally lit. Plastic cards (don't use your credit card!) are one of many other potential tools that will fit in that slot followed by a blast from your nitrogen tank. Measuring and adjusting the gas pressure was a good catch. With a manifold pressure of 4.18" wc, sooting could occur and build up in the heat exchanger.
HI Curtis from Winchester, United Kingdom. Our homes are all gas boilers so completely different and my experience is commercial rack refrigeration but still like to watch you. Maybe I move to USA one day hahaha
One time I had a no heat call in a manufactured home with the upright Coleman furnace in the closet. The gas valve would open as I could hear it click but it would not light. I removed the single brass orifice and found a spider inside of it. It had gotten inside the orifice during the summer time and grew. The bulbous part of the body was larger than the diameter of the orifice opening. Each time the gas flow started its body prevented the gas from exiting. I was so surprised to find a spider in there that was larger than the opening! 😳
I believe you had some debris in your orifice bud. The second time you took that thing apart, and you cleaned it, and you cleaned the orifice to most likely that’s what it was not the burners itself although I know they did have some spiderwebs in it. I don’t ever clean a set of burners without cleaning the orifice also. I think you probably already figured that out.
Ironically I have 240 volt motors on my van because when I was at one of my Suply houses I accidentally grabbed the wrong ones lol. I meant to get 24 volt I should have had my glasses on.
Mmmm that was definitely odd. You tried a bunch of different things….I was thinking flame sensor from the start…being it was working when it wants too….👀
Honeywell TH 8321 on almost every job. It has the settings for your heat pump with auxiliary heat backup. 3 heat and 2 cool. If you want remote capability with your smart phone, TH 8321wf. For wifi. $160. I have never once had a call back for a thermostat. The main difference between the 8320 and 8321 is the 8321 displays the indoor humidity. Otherwise, they are the same.
You can have too much gas pressure and it will literally blow the flame out. I just replaced a rectifier plug on a water heater that wants 0 to negative manifold pressure. One of the issues on those is that it can be too high.
Thanks Curtis! I am just a homeowner but have had a few rentals for years and this was a new one on me. I learn so much from your posts. You are the best!
Hey Curtis I've clean the crossover for the burners and spray it with high temp spray paint silver. Works everytime. Just letting you know. Thanks for the video. You get the paint at car parts store.
That’s interesting. A friend of mine had a dead earwig (bug) blocking a port. In my area, flame sensor issues are rare. Could that be climate related somehow? 15 yrs on old furnace, 5 yrs on newer, never an issue. The friend with the bug issue is pushing 25 yrs, no flame sensor cleaned. He had a heat pump, hated it and switched to gas. More friendly on comfort and bills when cold. NW Oregon for reference, nice climate, but we always think of giving it up for other reasons.
Glad the roads were better today. They probably don’t have much equipment to deal with snow down there. Good catch on the cob webs It sure don’t take much to affect the flow of gas
Had a granddaddy long leg get into the burner on a propane range once. I was chasing it down across the kitchen 😊. Wi😢my shop vac same deal, oven wouldn’t get up to temperature
My first thought was the orifice. Since you cleaned the orifice at the same time that you did the cobweb, you will never know the real problem. I carry a set of welding tip cleaners for cleaning orifices.
I retired from telecom. I hated "intermittent" troubles. Hard to chase and time consuming. Load sharing "power supplies" were a real pain in the butt to isolate. You really smoked out that orifice for sure. Take care.
I would've never thought a 240 volt motor is in a residential package unit. Rarely saw package units in the north where I used to live. Is this common?
Hey i asking you a question last week. I got no relpy . My unit has. What a good thermostat to buy. It a Goodman 3 TON Out side unit with the heatpump Rev value. And heat strips. What's the most commen one to use.

"The itsy bitsy spider crawled in the orifice..." With all the brown recluse you encounter, spiders continue to be your nemesis!
Using your meter probes to clean gas jets; you crack me up sometimes.😂
Get er done!
I'm so glad you and I figured that out Hammer on to the next one
Curtis,
Great call! Spiders Spiders everywhere you go!
The whole time I was watching I was thinking orfice clean the orfice. Enjoy the videos brother…👍
Nicely done Curtis, such a small cob web can prevent the flame from igniting 👍 Au

Well greetings from the State of Georgia
I always carried a test tube long brush to clean those out

I've only ran across cobwebs in burners once in my 25 years of hvac service. It amazed me how little it takes to disrupt gas flow. Good job.
Only once? That's just crazy. All the time where I live
When i am doing PM during winter, i always clear the cobwebs out…brushed or CO2 clearing
That unit looked like new. A little cobweb messed it up, crazy. It has been cold for sure and we need the heat. Nice job
Surprised something as fine as a web strand would do that. Nice fix on that unit! I'm always learning new things on your channel. Thanks!!!
Thanks

Curtis that was a difficult one but as always you got it done thanks for the video
You bet

Congratulations Curtis on Reaching 70k Subscribers. 👍🙏
Thanks
You used exactly the right thing to clean the oriface. The meter probe. Thats what I have been using since I started many moons ago.
Good find with the spiderweb.
How do I disable the emergency heat strips for a heat pump air handler?
A Lot of Areas had the Snow Melt next day. We have Snow and Ice left from a Hefty Storm we had almost three (3) weeks ago in the St. Louis Area. 🤔
Mmmm that was definitely odd. You tried a bunch of different things….I was thinking flame sensor from the start…being it was working when it wants too….👀

Would it been “harmful” to of used say “torch” to burn out the tube!

Great job. Waiting for hats !!
Thanks again.
No problem.

Congrats on 70k Curtis

Great fix. Love watching you at your craft. Thanks:)

It’s amazing how a spider web can cause issues like that. Can be frustrating sometimes.

I found a web inside the supply pipe. Furnace wouldn’t fire at all.
Nice work Curtis.
Thanks to the spider😊 you have a job
Had a granddaddy long leg get into the burner on a propane range once. I was chasing it down across the kitchen 😊. Wi😢my shop vac same deal, oven wouldn’t get up to temperature
I probably would have taken all 3 orifices out thats a clean unit
Wow interesting
Nice video thanks
I’m glad you liked it.

Here it is
Another good video Curtis, thank you!
Thanks, glad you liked it.
Curtis are you going to attend the AHR show in Orlando FL. In February?
Yes
Great video 👍👍👍
Thanks 👍👍👍
Nice work man 😊
Hey i asking you a question last week. I got no relpy . My unit has. What a good thermostat to buy. It a Goodman 3 TON Out side unit with the heatpump Rev value. And heat strips. What's the most commen one to use.
I use the Honeywell T-6 for those
Great video your videos are so informative. I have a question. What meter do you use?
Fieldpiece SC680
Can you fill the burner around to see if it happens on number 1
That is a one-piece burner, so "No".
😀😁
Gun shy Curtis 🤭
Yep
Get you a can of computer duster.
What do you use to film?
GoPro
Film ???? That stuff want away ages ago.....
Hey Curtis, when is your birthday??
Hey Curtis, how you doing tonight
What’s up
Way to many shots of Milwaukee screw removal !!!!! Unless they are paying you!
