gas furnace cycling on & off,will not stay on

[@12bravo68]

Thank you -12 in Colorado Springs this morning (Sunday) at 0400. Burner wouldn't stay lit. Never heard of a "burner sensor," much less ever cleaned one.... Truly, our thanks!

[@garylangley4502]

I just tried this on my Rheem RGPH, and it worked like a charm. Cleaned the flame sensor rod with a scotch bright pad, and no more problems. Thanks!!

[@crand20033]

This problem is so common I think we all should be cleaning our flame sensor at least once a year before the heating season. if you call a tech it will be $250 out of your pocket. We are warned to change our filters but no one tells us about this. I just went up in the attic and cleaned mine.

[@norrisgravitt3152]

I had his issue and went step by step of what he did and it worked. Thank you so much for this video. It was going to be a cold Christmas morning, but you saved us from that!

[@mrbubble185]

Good job. Nice routine. I like the crisp, concise (yet polite) way you communicate with the customers.

[@rfty19991]

If you hadn't cleaned the fan inducer vacuum port I would have never been able to figure out my problem. It was clogged with rust. Finally fixed 6 years later. I can't believe it was so easy. But first replaced flame sensor. But vacuum port was the issue. Thanks so much!

[@crand20033]

It was rusted? How did you fix it? Didn't you have to replace the inducer?

[@nukaprincess5166]

Love the truck ride and Happy dog! ☺️

[@ronaldcruzz]

Thank you for the video! I watched all kinds of furnace troubleshooting but yours actually worked for me. Some videos have all kinds of explanation but didn’t help me. No more cold nights for us!

[@ml2trick]

I own a old Boiler system in Wisconsin. I have learned more on your videos . Then any other heating person. You are a very good plumber and heating guy. Good Job Buddy and Thanks for the Knowledge

[@aircooledtx]

I use steel wool to clean flame sensors,and always stick a paper/clip into vacuum hole on inducer draft .Good Job, quick fix.. Steve. Arm chair technician..

[@Rezcat-y6r]

Good morning, Steve. It's 5.30 here on the west coast. Having some morning Joe and enjoying the video from Massachusetts. It looks like an awesome autumn day! Scotch Brite is a great cleaning tool. Not as abrasive but it gets the job done. I use it for backflow repairs always. Great job as always. A nice little service call without making the customer feel belittled. Great customer service. Love Baby's little vest. Master HVAC tech! God bless.

[@darrenskinner5928]

Baby dog looks like she is loving her new life that's awesome

[@jessicaquinn6261]

Thanks for the videos! My furnace was doing this same cycling. When I called for service I told the tech I thought it might be just a dirty flame sensor. He immediately thought I knew a thing or two about the furnace. We started taking in furnace jargon and I actually knew what he was taking about. It's nice to have this type of knowledge so they can't try and tell me I need something I don't. So yeah, it wasn't a total shit show. 😉

[@philllsxga.7737]

Knowledge is power!!

[@lucasgarman2379]

Thank you so much!!!! My furnace hadn't been working in a couple of days. Furnace guys were out here this morning, replaced the Ignitor Coil. Still did not fix the problem. I just got done cleaning the flame sensor and now it's been running since and pumping out the heat I need!!! Thank you again!!!

[@MrFrozen73]

Good job Steve ! But those old Goodman are well known to have cracked heat exchangers, I had found few very different then tubular heat exchangers.

[@leelc211]

Keep up the videos, I really enjoy them, your good at what you do. Awesome dog.

[@ryanclark9386]

Would a damper not opening right stop the furnace from lighting? Idk if I'm crazy but when I put a little pressure on the little metal bar coming off the little motor it kicks the furnace on

[@flycow69]

Thanks Steven you saved the holidays with your tip. I work on all my major appliances when they break down. When my sister in-law called that her gas boiler zone one was not working I went to your old utube videos and because I forgot my tool bag. I didn’t bother try to remove the flame sensor. I managed to cleaned it with an old Dollar bill and voila the boiler is working so far for 3 straight days. Thanks again and Happy Holidays

[@Pete4875]

If you were my furnace man I would have it cleaned and check regularly. My last guy put a open fan motor in my outside AC unit. Than a year later after it failed again, told me it was planed obsolescences and the new motor would be $600. I trusted him for years who knows how many times he screwed me. I took the fan apart myself. Bought the right enclosed fan, the right capacitor and put the wiring back the way the schismatic showed. It cost me about $150.

Hello. Great video. I live in an apartment and the gas furnace stops working during a power outage. Can I connect a vehicle battery or some other power source to the furnace so that it will run during power outage? Thanks

[@josephcade3541]

Great job Steve and very nice video hope you and doggy doing well. You know Steve your dog gives more affection than any woman I've ever dated is it a purebred or what

[@JustPlumDucky]

Some older mobile home standing pilot furnaces... when the pilot is lit for the first time of the heating season, will short cycle on & off, with each ON cycle progressively lasting longer and longer until the unit will finally stay on continuously until set temp is reached at which point t-stat will shut it down. I remember someone telling me long ago it was because the furnace was so cold due to sitting in cold weather so long before starting it up, but can't remember the exact reason cited. Is it because the lower (as opposed to the "upper" aux limit (manually resettable) snap-disc-type limit (the "high" or primary limit) is tripping prematurely and has to warm up a bit before it will let the unit run continuously toward set temp?

[@paulrobilotti9294]

I had the problem, the repair man came, said the following furnace to big for my home, duct work may not be able to handle the load, make sure your vents are all open, filter clean, what was happening was the safety switch was getting to hot and was turning off the furnace cooling and it went on again, so being the furnace was putting out to much heat for my system he lowered the gas pressure which causes the flame not to be that hot and yes the home heats up as quick as it did before and let the fan go a little faster, everything now works.

[@davidbradley3074]

Is corporal woof in training?

[@cassandrakeefer7385]

Keep in mind that when doing these "no-heats," if you're going to give a tune up, give the full tune up so you're respecting your customer by fixing the issue for the full year a tune up is good for. AKA; cleaning full inside cabinets, toothbrush to "dust" off any access, take out burners and clean with wire brush, make sure all wires are GTG, check filters, temp rise, CO levels, gas pressures, etc. to ensure this issue won't happen shortly after. Explaining it better to the customer also helps tremendously on why getting routinely preventative maintenance's can save a ton of money and catch issues before a no heat occurs.

[@johnbennett6826]

Very nice dog mate

[@craigtimm774]

Thank you! I'm sitting in a cold house that is getting warmer by the minute.

[@rachidcatana1266]

You got best assistance ever. Cool

[@phoenixhvac-r828]

Just started watching your videos, good stuff, most of the time it is the flame sensor, cleaning vacuum port always good idea, but I think you solve it when you shortened the vacuum hose to get rid of the kink in it,good catch.

[@Fireship1]

Flame rods make us money. Lol. I clean them with 000 steel wool or scotch brite pads. Was taught never to use sandpaper. The silica can embed in the rod and melt with the heat contaminating the rod and making the unit continue to trip out.

[@crand20033]

I just cleaned mine. I plan to do it every year. Took 10 minutes.

[@phillipgroom9187]

Nice easy job. Thanks for the video.

[@crand20033]

My flame sensor and ignitor are behind the valve. Damn near impossible to get to the screws unless you have special tools so you have to undo the manifold and move the valve out of the way.

[@jeffreyparson8824]

Thanks.... help me to fix my problem . Thanks again

[@JasonSmith-qx3zh]

what do you use or what's best to use to clean the inducer holes or exhaust port.

[@sknight0391]

Jason Smith Piece of thermostat wire is the easiest way. Or you could get a tiny diameter bottle brush at a gun shop. They have a lot of different sizes for cleaning firearms. Or tiny screwdriver will work also.

[@geraispadilla213]

Thank you for the sandpaper trick. Worked like a charm. 👍 Definitely subbing after this.

[@Skier460]

If the heat exchanger was cracked, wouldn't you read 0 CO in the supply air? Because the heat exchanger has a more negative pressure than the ductwork when the blower is running causing supply air to leak into the heat exchanger?

[@walterharris1814]

What was Code on Board? All Goodman and other Furnacees have a Diagnostic Board on them. You should look at that before turning power off.

[@bepositive3040]

You are great thanks for this video

[@jonathansmith3019]

Thanks for posting Steve. I love the easy ones!

[@picklerix6162]

That furnace looks just like my Goodman GMP. I had a similar issue but my furnace control board was bad ($78 with free shipping). Cleaning the flame sensor didn't fix it for me. The vacuum hose on mine wasn't kinked but it did look a little crusty so I cut off the crusty part and reinstalled the hose. The inducer motors are loud as hell on these furnaces so I replaced my inducer assembly with a newer Goodman inducer fan that runs with much less noise. I also replaced the cracked plastic chimney that connects to the inducer. I hear that Goodman has a recall on that plastic chimney but the distributor wouldn't give me a new one for free. He did sell me a new metal chimney for $9.00 though. Who puts plastic in a hot air furnace vent? That's just stupid.

[@harrydickson4575]

Good work Steve

[@6977warrior1]

If the furnace is old, like my Thatcher unit, it doesn't have a flame sensor. It uses a thermocouple. That would be the culprit, correct?

Why do you guys have to leave a orange tag on the unit ? I'm from Arkansas and I'm not aware of any code for that here. Thanks

[@weakyweaky8019]

They leave an orange tag with his company name /phone etc and also room to date and brief summary of repair. When customer opens door to look at furnace he sees your company name so he will call you again. And next tech has an idea of previous repairs.

[@Jeepjones85]

Okay I can see that, just curious lol

[@coryseaward975]

Right at the 2.46 mark, you can see the pressure hose is kinked.. Inducer motor hose won't be able to send the right pressure reading... Boom, instant problem right at the first sequence..

[@heatncool]

Good video. You use carbon monoxide detector to check for cracked heat exchanger all the time? Does it just beep or tell you a reading of how much it's detecting?

[@skipd9164]

Learn what your flame looks like. It usually stands lall and straight. This is old school but if you see the flame dancing you could have a problem. Im not talking all flames just in little area. I hated hot air gas heaters . Its alot different now with co detectors. One of the first things we would ask is anyone sick.

[@jandjmca]

Mine runs fine with top panel open, as soon as it is closed , starts short cycling furnace(90.2 +) was installed last march so this is first winter, I know it is under warranty but not the labor and installer is 50 miles away

[@sknight0391]

Hey Steve, are you still using that same model of carbon monoxide detector? If so I'm wondering how it's still working out for you now? I like the idea that they're made in the USA.

[@JamesSmith-rl7nb]

Carbon.... The great insulator. Carbon up a boiler= no heat transfer. Carbon up a flame sensor. No flame signal

[@ryanleblanc6810]

Where do you get that CO detector?

[@fillowtree5505]

Steve, can you do a video of all the meters and testers you have? Never have seen the CO tester you just used. You always surprise me with a new tool. Plumbing and HVAC has surely gone high tech.

[@MrDonny27]

Hey

[@kenthomas4668]

That furnace even with a cracked hx will NOT put co into house. It will get house air into flue gases because of higher pressure from blower.

[@BADAZZ93STANG]

Can a flame sensor actually go bad?

[@sknight0391]

BADAZZ93STANG Yep, they can go bad. Porcelain can crack and then you will short to ground. The porcelain is there as an insulator. Most furnaces need at least 1.6 uA to run properly. You can take a reading with your meter before and after cleaning and be amazed at how much it goes up. In the 3uA range is good.

[@BADAZZ93STANG]

Shannon Knight thanks!!!

[@JDfromWitness]

Just a metal stick that bleeds off voltage when in contact with the flame, which lets the controller know there is flame. They get coated and the coating doesn't conduct, therefore controller thinks there's no flame and shuts it down. Clean down to the metal and it's good for another 5 years.
