finally , I can listen to this man explain all day long. Very detailed, not to assume everyone watching is master hvac. People are always starving for good and detailed info to learn from. Thanks, great job
i like that every time you introduce the next step in the sequence, you still start explaining from the very beginning of the sequence. Really helped drill it in. This was excellent!!
I have spent hours studying HVAC systems on the internet. This one is hands down the best I have seen to date. You are an excellent teacher and I thank you for sharing your knowledge. Captain Ron
I'm an HVAC Tech going on my 2nd year in December. Just wanted to say this video is the best video I've seen thus far on troubleshooting a furnace. Great video to refresh my memory.
I have 6yrs doing hvac tec and install ed for a compans and I never have a problem how to fix it, all that you need to know be with the right service tech and ask questions if you have to.i like to watch hvac videos from others tech to get some tips and apply it in the field and it work, not complain . This guy splained very well
Excellent explanation for a DIYer and complete noob in the HVAC world. This video allowed me to know exactly what I was looking at. It also allowed me to function test all components before taking anything apart. Truly thank you Sam!
I don't know the first thing about electrical, but when my ac compressor wouldn't kick on today, I knew I had to figure it out on my own. This video has really given me the confidence to troubleshoot my system. Very well spoken, detailed, and laid out information. Thank you!
Sam, this is one of the best presentations on the topic. I am part time tech, and it was excellent to be refreshed on all the minor details. Will look for other videos from you. Thank you.
Omg this guy is such a great teacher, he repeats himself just enough to be sure I have captured his messages. His delivery rate is at a speed that I never become overwhelmed regardless of how much useful information he delivers. What a great furnace video Sir.
I'm writing this from a new tech stand point. One of the best if not the best video I've seen on troubleshooting a furnace, no fancy terms simplicity yet filled with information!!! Great job Sam thank you for not rubbing on our face your knowledge and making it simple for those of us starting in the HVAC field!!!
By saying the wires are interconnected, means they are all in series, if any one the safety devices open then the furnace will open and shut down. I believe. I would have liked to of seen a wiring ladder diagram. But this was by far the best explanation I’ve seen on You Tube. I’ve had some electrical experience and I enjoy watching these video’s. Always learning more. Thank You
Sam, this is the best in depth explanation I've ever seen. If you aren't an expert you sure fooled me brother. Thank you, as well as your furnace for being the guinea pig multiple times. That was the best 26 minutes I have ever spent on youtube :) You have a new sub from me.
Sam you are an excellent teacher !! 👍👍 . Thank you for the perfect quality and lighting. I replaced my board exactly like yours, no heat... hit the roll-out resets and BOOM, We have Heat and my beautiful wife is happy. 🙏🙏💜
repeat repeat repeat........I loved every repeat of the operation. I am exploring repairing my furnace....Your presentation gives me confidence. Thank you.
*GOOD STUFF BROTHER* ... As a stubborn *IT* guy...I refuse to call a tech to fix anything. I have been diagnosing and repairing my furnace for years... Knew some of that stuff... But never knew the entire process until this video... *THANKS THANKS THANKS* *LIKED...SAVED TO FAVORITES.. AND SUBSCRIBED*
I’m currently in HVAC school. This semester I’m studying gas furnaces and electric motors. This is by far the best video explanation I have came across.
My man… 😮 you are the best instructor online ever. Seems like you follow the current flow point to point… great work! Yes I learned and subscribed, yes sir…
Best way I have see trouble shooting a warm air furnace . Love the fact that you took your time and explained all different scenarios. Also the way you talked slow and clear . Most people talk way to fast and jump around from topic to topic. Nice Job Sam keep them coming. And remember if you don't use it you loose it. If you share it its yours for ever. If you keep it to your self there is a chance you may loose it . I had to learn this the hard way.
I just want to thank you for this video. I bought the igniter for my furnace and I thought it was going to work but it didn’t. I followed your video step by step and it worked. God bless you and yours my friend.
Thanks Sam --- as a note - some of these air switches has two contacts - one on the front one on the back check both! On my Carrier unit the yellow jumper powered both switches - then there was a brown (signal to control board) and orange (signal to control board) two different outputs signals. Inducer housing pressure and collector box pressure (check all 3 tubing- green, black, and black square tubing vacuumed sensing signal). Blow them out (toward the inducer housing) and you can check them with a OHM meter by gently sucking on the hose and hearing them click. Make sure the hoses are good and tight - a very small vacuum leak can cause them to not work!
I have been messing with furnaces for about 10 yr and currently in hvac school. And I can tell you that this is well explained and one of the best vids I have watched, thanks for taking the time and effort to make this vid
Wow. That’s the most complete and comprehensive walkthrough I think I’ve ever seen. A natural teacher. Maybe you should consider joining with Khan Academy…seriously.
Wow, that was absolutely perfect ! Your illustration, camera work, and explanations..spot-on ! I would have liked to see the flame sensor, and how to clean or replace it. Fantastic..!
This is awesome! Just a suggestion that what would have made it more awesome is a 15 second talk on what each of those pieces does like "flame sensor is there to detect that you actually have ignition and flame and if not it turns the furnace off to prevent gas leak"... things like that.
Sam your a good teacher,u speak and teach at good pace.Your easy to follow and understand. Although you are very wrong,an inducer running or verifying(what u call it) isn't what closes a psi switch .The psi switch has a tube going to it that tube is connected to the housing of the inducer,when the inducer runs in a system that doesn't have a chimney problem, chimney pipe problem, heat exchanger problem etc the inducer running creates a vacuum that the closes the psi switch normally open contacts. Not all blower mtr run on a call for heat for 90 seconds, thats that furnace, thats not all.Roll outs,high limits psi switches are not INTERLOCKED ,thats called wired in series.In the beginning u said u were troubleshooting a board,so why would u use LINE voltage ground and not your LOW VOLTAGE NEUTRAL?Your low voltage neutral is common.Your discussing a gas fired furnace and u speak about the flame rod for 15 seconds?That rectification signal keeps the dam thing on,if thats not a good signal bck tothefurnace it won't wrong for 12 seconds.For some reason the flame rolls bck,FOR SOME REASON,howabout for these reasons,a bird nest in your chimney, water in your chimney, a brick chimney that fell apart,a cracked heat exchanger, a blocked secondary,a drft mtr with no squirrel cage that doesn't use a psi switch but rather an end switch.AND FORALLTHESE REASONS THATS WHY A ROLL OUT WOULD POP(the resettableswitches)Start up process,the industry lingo we call that a sequence of events.I JUSTHEARD INTERLOCK AGAIN,roll outs wired in series.GOOD JOB BRO,keep upthe good work
I just wanna know which genius thought it would be great to place a flue in front of the blower assembly. True stroke of genius right there. That an entire company signed off on. Truly phenomenal.
I just watched your video. I'm a hvac student. This is one of the best videos ever seen. You are great teacher. I really appreciate your video. God bless and keep up with great work. Thanks again.
Hello I just came across your video. Excellent tutorial video. Very in-depth video. I’m a homeowner and my hobbies are mechanic s, electrical, plumbing, carpentry along with others. I like to diagnose and repair problems. I know repair cost are high but one time I was charged extremely more one day I had service on my furnace when I was working. No more. I plan on taking a HVAC course. Looking forward to seeing more of your videos.
EXCELLENT explanation I have never ever SEEN such technically wiring explanation cycle ON RUclips. "GOD BLESS YOU" my friend keep making more videos' VERY LESS PEOPLE HAVE SUCH TALENT TO EXPLAIN the real world knowledge. Every HVACR guys should watch this video again and again till they get MASTERs of FURNACE wiring.
1# Gas Furnace Operations Video on RUclips UNDISPUTED!!!!! When I began hvac at apartments awhile ago, just finding a video where the tech didn't go off on unrelated information, advance functions, random applications etc was impossible.
Beautifully explained the complete flow of signals. For a dumb person like me understood the entire process. Best thing is repeating things again and again. Best video sir. All I can give you is respect
WOW I have spent hours and hours and hours trying to find a video like this. This video is the best that I have found and probably ever will find, on trouble shooting a gas furnace. For those of us that are trying to find out what is wrong with our gas furnace, In my opinion this is the video we need and have been looking for. Thank you so very much.
Wow! You are so very talented and so very generous with your time to help others! You're an excellent instructor! Thank you so much for the hours and hours you put into producing this amazing, comprehensive troubleshooting a furnace using a mm tutorial video. I would like to add that your voice is calm and clear. Thanks for no music and excessive yacking. By far the best tutorial I've ever seen. I have watched numerous YT videos and I finally found one that will help me my particular issue and more! I subscribed and look forward to seeing your other videos. I will also look to see if you have a link for $$$$ donations $$$$ to show appreciation for your time and talents. God Bless you Sam.
I’m very impressed with your thorough, methodical, and informative video, I don’t mean to nitpick but instead of using electrical tape to close “hold in on position” your furnace power switch, might I suggest that you just try pulling it out, same as setting a fan limit switch to manual. Keep up the good work, maybe it will get some of the people who bother me at ridiculous times to realize that they could do it themselves, I was called at three o’clock in the morning on Christmas Eve to fix a boiler and again on Christmas Day to do a forced hot air furnace and I’m not even a furnace technician. . . I’m just “Blessed” with the ability to fix things.
Sam, you did an excellent job explaining the furnace start-up sequence with trouble-shooting tips every step of the way with a multimeter. I benefited even more since I have the same exact downflow/horizontal furnace (a Payne model PG8DAA). So, it was like you were at my home explaining my furnace to me. 🙂 Thank you!
I have seen a lot of furnace videos on the net but yours was the best one yet I don't think it gets no better than this one... it really helped me out a lot I just want to say thank you and keep up the good work!!!
Thanks so much!! I took 3 months class learned AC but didn't really know anything, your video is a tremendous help, thanks again. Please make more videos like this about the AC system also!! I will be sure to keep an eye on the new one you make!
🏆 Thank you for your helpful and detailed guide to troubleshooting HVAC systems. Hands down your video is one of the best one that details all provable causes and how to test components with a multimeter.
one fine job, any one manically inclined should save this video if u try to work on a gas furnace. i know i won"t remember all this but i'll have it to watch when i need it. you will never find another one even close. very precise, thanks for helping
Thank You! Sam, you literally did the most golden video in youtube overall, you definitely deserve lots of respect on the knowledge and great experience you have given here in this video is really understandable and no confusion at all.
This video was very informative. I am an HVAC/r technician and even if I wasn’t, I’d be able to understand this video clearly and precisely very good teaching method thank you so much for the information
Great run down on trouble shooting a gas furnace I never really trouble shooted a furnace I just went off the diagram and the lights blinking indicating the problem I rebuild a whole gas furnace in over two years due to it being in a flood that I wasn't aware of but I appreciate this
DUDE Thank you!!!!! This is one of the most complete furnace videos i have seen. I have been having problems with my furnace and have been looking for the exact technical data you gave in this video like voltage and Ohms for specific parts. I will be using the knowledge you gave me in this video to completely troubleshoot my problems. At this point though with what I learned from this video I believe my furnace control box is bad.
Thank you so much for this video! Our furnace is exactly the same as the one here and so I was able to troubleshoot and fix our furnace for only $17! Come to find out, it was only the igniter. You saved us a technician call. Thank you!
Ignitors usually fail every three years. Keep a spare ready. Same with capacitors on outside ac condenser unit. Be up and running in under ten minutes. Easy fixes.
I don’t mean to be a wiseass but instead of using electrical tape to hold your power switch in the closed position “on” I find that pulling it out, like setting a fan limit switch to manual, is more practical. I’m very impressed with your thorough, methodical, and
This technical approach to troubleshooting is what I have learned in electrical schools ( in Europe) , and it applies for ANY electrical appliances. It is of course necessary to FIRST read the electrical wiring diagrams of the appliances do you figure where to test with a multimeter.
Thank you so much for this video. Your explanation of the whole process was so informational and helpful for someone who has no experience working on hvac stuff. It made it very clear and easy to understand how each step in the process leads to the next.
You’d get more than 1 like for such an informative & extremely in-depth explanation in the trouble shooting of a gas heater. This probably 1 of the best videos I’ve seen so far. Excellent job!
Excellent video Sam. It's very informative and detailed. I do have a couple of points to make. I've been told on more than one occasion that cleaning a flame sensor with sandpaper is a bad idea. The silica in the sandpaper left behind on a flame sensor can turn into glass when exposed to high heat, which might cause the sensor to malfunction. It's best to use emery cloth. Also, mention how the pressure switch closes when the inducer motor runs. The inducer motor pulls a that causes the pressure switch to close.
From Argentina. Thank You Sam. Whith your explanation I resolved the problem in my weathermaker 8000. one of the temperature sensors is faulty. I replace this and it worked perfect.
Excellent video, running it forward and backward, multiple times, explain what is verified at each stage, and also troubleshooting guidance if problem exist at various stages. Subscribed with my bell on looking for future video gems.Great stuff.
Excellent! Helped me understand all the parts, the sequence of events, and how to diagnose where things were going astray (my unit is a horizontally-mounted Trane TUE080A936K which has hot surface ignition). As such, this was even more helpful than "Top 10 Furnace Problems" (which actually covers 'top 30' or so), though Top 10 gave repair steps for each of the issues.
finally , I can listen to this man explain all day long. Very detailed, not to assume everyone watching is master hvac. People are always starving for good and detailed info to learn from. Thanks, great job
i like that every time you introduce the next step in the sequence, you still start explaining from the very beginning of the sequence. Really helped drill it in. This was excellent!!
I have spent YEARS studying HVAC and this is by far THE most complete video tutorial on gas furnace operation/troubleshooting
👍👍👍
I have spent hours studying HVAC systems on the internet. This one is hands down the best I have seen to date. You are an excellent teacher and I thank you for sharing your knowledge. Captain Ron
I completely agree. Captain Ron broke it down to a T no other video like it thank you
Very well explained troubleshooting and furnace operation procedure. might want to have a script next time
Get a software called delmar hvac simulator. 100% will make you a better tech
@@subpoenacontrol3799 didnt he man ALL the way to the T the rawedt
I'm an HVAC Tech going on my 2nd year in December. Just wanted to say this video is the best video I've seen thus far on troubleshooting a furnace. Great video to refresh my memory.
Good but he miss to mention FLAME SENSOR 🔥 WHICH ESTABLISHE THE FLAME FOR CONTINUES FLAME.

You such great teacher, with detail furnace troubleshooting explanation, l have no enough words to say thanks for the great content of this video
Just wanted to say thank you😊. Your video had key points that helped me getting my furnace to work after I replaced the motherboard.
Good video. He misspoke a few times with terminology but if you're using this as a guide you won't be affected.
Im loving this tutorial. Very grateful. Saving this spot 17:13
Best video on troubleshooting furnace. I fix my furnace in 30 min 🤣🤣🤣 no joke. Subscribed out of respect.
Thank you for this tutorial, absolutely the best I have ever watched. I learned so much in about 30 minutes.
Based on your video, I was able to have a starting point for troubleshooting the missing low voltage issue not at the pressure switch. Thanks.
You’d get more than 1 like for such an informative & extremely in-depth explanation in the trouble shooting of a gas heater. This probably 1 of the best videos I’ve seen so far. Excellent job!
Right on, man. Thank you. Good work. You just fixed an older womans heat. And it is COLD, out here in Alabama. We aint accustomed to this kinda cold.
Excellent video Sam. It's very informative and detailed. I do have a couple of points to make. I've been told on more than one occasion that cleaning a flame sensor with sandpaper is a bad idea. The silica in the sandpaper left behind on a flame sensor can turn into glass when exposed to high heat, which might cause the sensor to malfunction. It's best to use emery cloth. Also, mention how the pressure switch closes when the inducer motor runs. The inducer motor pulls a that causes the pressure switch to close.
Sam, Thank you man. I am gone watch again and again l. Best explanation ever.
This is a very good video. If noone knew the series of operation, this will explain it. Thanx for the video
Great video Sam, you did an excellent job of explaining the furnace parts and sequence of operation. Thank you.!!!
That is exactly what I learned recently but I was confusing . Then your video explains all. I am so glad I watched your video. Thank you Sam
From Argentina. Thank You Sam. Whith your explanation I resolved the problem in my weathermaker 8000. one of the temperature sensors is faulty. I replace this and it worked perfect.
Excellent video, running it forward and backward, multiple times, explain what is verified at each stage, and also troubleshooting guidance if problem exist at various stages. Subscribed with my bell on looking for future video gems.Great stuff.
extremally thorough like all tech videos should be . thank u very much for the content !
Excellent! Helped me understand all the parts, the sequence of events, and how to diagnose where things were going astray (my unit is a horizontally-mounted Trane TUE080A936K which has hot surface ignition). As such, this was even more helpful than "Top 10 Furnace Problems" (which actually covers 'top 30' or so), though Top 10 gave repair steps for each of the issues.
