Thanks for showing me what to do. Stan
I know Im asking randomly but does someone know of a tool to get back into an instagram account??
I was dumb forgot my password. I would appreciate any tips you can offer me!
@Bryce Sergio instablaster =)
@Jameson Kasen I really appreciate your reply. I found the site through google and I'm trying it out now.
I see it takes quite some time so I will get back to you later when my account password hopefully is recovered.
@Jameson Kasen It worked and I actually got access to my account again. I am so happy!
Thank you so much, you really help me out :D
Your home-made models are crafty, very crafty. Thanks for being so thorough.
Glad you like them!
This video is hands down the best/most detailed explanation of how a water heater combustion works!
The idea that a spiderweb was messing up my ignition! That shows practical experience. A very straightforward explanation, and a total lifesaver after our pilot light needed lit. Thanks!
That dust cleaning on the contacts just saved me an expensive call! Thanks for putting together this video
I am a RUclips go-to for every problem. You are extraordinary - must be a teacher.
I love learning basic home maintenance with Kermit.
Cannot thank you enough for putting together this excellent video! Saved me a lot of time, money, and trouble. Thanks to you, after a couple of hours I had the new parts and a working water heater, you sir are an absolute mensch!
Man, your videos and explanation are unarguably the best out there on the net. Amazing work.
My spark wire wasn't grounded right.
Two different plumbers talking about, "be a few days."
5 min into the video had my answer and fixed it myself. Appreciate the video man
Thank you so much for this video and sharing your expertise! I have been struggling for 2 days, since the power return after 5 days without, to get the water heater relit and your explanation helped me to see what I was doing wrong. Here's to a hot shower, FINALLY!
A spider web in the tiny slit beside the igniter button fouled me up! Super easy fix. Thank you! It has been days since I had a warm shower.
The best video ever on gas valves!!!!!
Thanks a lot Sam!
I agree. This should be the first video to watch when troubleshooting.
Ki
Just under 20 minutes, I learned so much.
Simply the best video on the subject! Great job!
Wow, thanks!
At the 2:20 mark you helped me figure out how to get my heater fixed. I just held down the pilot light longer than two minutes to warm up and get that magnet to kick in
ME too now it is working
Thanks so much for posting this tutorial. The demo model you used was quite similar to my water heater setup, so, it gave me the confidence to take out the burner assembly and replace the thermocouple. Problem solved. I now have hot water again, and, it only cost me $13! With much appreciation - Steve
The amount of times I’ve had to watch your videos in the field is astounding. That being said thank god you make content otherwise I think I would’ve quit HVAC already.
May the Lord Bless you abundantly for helping others. In 5 Min I had the water on. Thanks a Bunch!!
And that’s how it feels to learn from a ‘true’ technician! Thank you so much!
Our pleasure!
This video is GREAT. Covered the reasons things don't work, not just how to replace them. Brand new water heater install, Piezo doesn't work, not grounded. Works now. Thank you!!!
Very very very helpful video. After pressing the ignitor I didnt think it was lit until your video showed me it burns very low & clean until depressing the pilot button & turning up the heat. Thanks alot sir, you saved me a serivce call for something super simple. Clicking the thumbs up button in this video
Darling husband fixed our water heater after listening to 1:23 of your video. Thank you, thank you!
This is the definitive go-to that even an arts major can grasp. Excellent work! Looking forward to a hot shower.
Wow! Could not possibly be more clear, thorough and direct. You should teach a course on troubleshooting-video production!
I've replaced my thermocouple at least a dozen times, but had more messed up this time ... and I learned a TON from this video. Thanks!
Thank You for putting this video out here, I was able repair my water heater. It was the thermocouple, saved me lot money was thinking of new water heater. Prices for new ones are outrageous.
This is the absolute best video I've ever seen in 7 years of struggling with my pilot light.
Thank you so much 🥰 I haven't had hot water for 2 days and just fixed it watching your video 😊
Glad I could help!
Thank you for making this great video. I am a plumber in Hawaii and just sent it to my retired HVAC friend in California because he replaced the thermocouple because pilot wouldn't stay lit and now when the burner comes on it sucks out the pilot. That sounds like a gas pressure problem. So I told him to call the gas company and test with a manometer before he does anything else.
Thank you so much for this! I had tried over and over again to light the pilot on my water heater but after watching this video, it took me less that 2 minutes! I was getting ready to call in a professional!! You save me lots of money!! Thank you, thank you, thank you!!!
Another great video starring a true technician! Thank you for sharing your knowledge with me! Great teaching on this subject!
Glad you enjoyed it!
I have been looking for some helpful information about how to light up the pilot, and I found yours... and let me tell you, it is the best video with real solutions I have seen. Thank you so much for this complete and professional explanation!!❤❤
Thanks for sharing this detailed video. The most comprehensive explanation on RUclips !
Glad it was helpful!
Thorough and to the point with superb video graphic illustrations. No other RUclips demonstration was better. Thanks for the attention to detail.
This is an awesome video lesson on household water heater. By far, the best I’ve ever watched. There’s a lot of science of physics on water heaters and HVAC ( laws of thermodynamics, electricity, even chemistry). Sadly, Americans today take from granted and casual, these appliances that makes our lives much better. I soon will be enrolled in a 3 week, deep hands on HVAC, no fluff program, to become a technician and then later on a certified HVAC man! Thank you very much for this video. I already do water heaters installations for people but never learned these troubleshooting at once like this. Thanks !
Thank you for making such an excellent video that explains all of the many possible issues with a water heater pilot light. You should be teaching classes at your local trade school!!
Anyway I woke up Sunday morning to no hot water.
I tried lighting my pilot several times without success
After watching your video I tried the 1st thing - the igniter wasn't grounded. I cleaned out the area and made sure it was touching the gas control box
Then I tried it again and SUCCESS!!! Pilot lit!!!!
Again thank you for making this video and sharing your vast knowledge with homeowners
I greatly appreciate it!!!!
Thank you, used compressed air around the green starter button and it worked! Avoided a service call charge.
Best video I have seen, in terms of explaining how things work. Once you understand how they work, you will do a much better trouble shooting job.
Amazing video! Thank you for the detailed info delivered in an understandable and efficient manner.
This is an excellent video and I have saved it away for future reference. Very comprehensive. I wish I were home right now....
I'm away right now doing chores for my 96-year-old dad. I got a call from my wife saying there is no h/w. Bummer. After looking at some so-so videos, I found this one and wish I were home to fix it myself. My wife tried lighting the pilot but could not. I still have 4 more days here and she needs h/w, so we'll have to spend a few hundred bucks to have someone else do an easy repair.
You are a true professional and an excellent educator. Thanks for the video!
Glad it was helpful!
You are a bloody legend mate, thanks for your informative and well put together video. I also like that you have taken all the main bits out of a heater to display the workings of a gas HWS.
EXCELLENT explanation of how the water heater works! Thank you!!
G2 service tech here, just wanted to say how great this video was, excellent explanation and service techniques, all the best

Thanks a lot! Make sure to check out our website to www.acservicetech.com thanks!
Perfect video it’s never enough for me just to do a quick fix and on to the next job. It’s real important to understand how everything works and why and why a potential problem exists. This video does it all and I thank you very much. I now understand all the workings and problems that can arise. And most important how to safely repair as needed. Thx again love to learn.
Probably the best instructional video out there about gas valves. Thank you!
This is a very comprensive troubleshooting video. Thank you for the time and energy it took to put this together.
Very impressive ! Thank you
Thanks, man. This saved me big time. Follow1ed your instructions to light the pilot, and it is working now.
Always way ahead of the others. I got exactly what I needed in much more detail. May Jesús, Mary, and Joseph bless this channel and all that work 😇
Great video with understandable English and explanations.
Great job Craig, excellent overview. Thank you!
Glad it was helpful!
Saved me and my lady. Did not have hot water for a couple days, then troubleshooting with your advice I got it going!
Absolutely fantastic. You walked us thru the X-ray of hot water tank. Many thanks.
Thank you so much!! You said your name to fast I didn’t catch it but I watched your video went down stairs removed the entire burn assembly cleaned everything the way you described in the addition to all the rust from the tank laying on the burn!! Put everything back together and I had hot later yesterday evening. Pretty much saved my bacon. Checked this afternoon pilot light was still on and I had hoist water. I know eventually I will need to replace but your tips worked beautifully!!!! Thank you so much
Excellent. The best that I have seen since leaving Sears and So Cal Gas Company training. Thanks for sharing your knowledge. Stay safe.
Thank you a very easy to understand description of how things work, just ordered a new Thermopile as the voltage was around 500mv.
Great to hear!
I wanted to say,
This video was very educational and gave me insight on where to start with my water heater. For me, it was the thermocouple that went bad.
But before last night, I didnt know a thing about this Trade. Thank you for such an informative video.
Thanks. Excellent video with clear explanation. Now I understand why our gas hot water heater may not be igniting; lack of spark or lack of gas to pilot. Simple issues but getting a techie to come out and do the job probably will require that I take out a second mortgage to pay for multiple visits before it gets sorted. And that excludes travelling time and tool time and apprentice 's costs. Buying and fitting new unit is probably less expensive.
Thank U very much! 10:22- Measuring Millivolts of Water Heater Thermocouple with Multimeter fixed my problem. Voltage reading went negative!
Excellent!
Thanks so much. Great resource for any homeowner DIYer.
This is the most informative video ever. Thank you for your help
You're very welcome!
THANK YOU FOR YOUR IN-DEPTH VIDEO. YOU JUST SAVED ME A LOT!
What a brilliant, useful and efficient video. Thank you so much!
Great Job! Not many like you. Your not playing games. You Truthful want to help people in detail. Plus leaving all important detail covered. Great job. After tearing the heater apart. I felt like a hero for my family. The next morning the temperature dropped. Yet people need to have at least some common since on understand that this is gas so read very correctly before proceeding. Thank yup
Outstanding. Great video. Thanks
Craig, Thank you for sharing your knowledge. Great info. that can always be trusted.
You are very welcome
Excellent video, i watched 10 videos before this one, when i get here, i solved the problem, thankyou so much.

Glad it was helpful!
Thank You....I had no idea the white part with the wires had a reset button in the middle.
Once again, the University of RUclips comes through! I used a small wire brush to clean the thermocouple and booyah - hot water!
4:55 Thanks for using the proper grammar!
Hands down the best video explained everything awesome job you fix my problem in less than 5 minutes I subscribed😅
What an excellent and detailed explanation!

Excellent instruction. Well done. Thank you.
Thank you for this video. Very informative and saved me a service call.👍🏾👍🏾👍🏾
This is well explained in a lot of detail thanks for sharing
Está explicación es súper informativa , muy interesante Gracias por compartirla 👍
Another great video, very informative, thanks again for sharing your knowledge.
So nice of you
Thanks a million. You have covered it well.
This is really helpful. Thank you for creating this great content!
This is the last video anyone needs to watch when it comes to fixing your problem /problems your having with your waterheater. But if you still can't solve your problem after watching this video? Then im guessing your that type of guy who's microwave is still blinking "12:00" over & over again & has black electrical tape over his check engine light in his car. Basically what im im trying to say is "you'll really like this video"! K. Keown Evansville, In
Great class teacher, I feel more confident with this knowledge now 👍👍
Awesome to hear, thanks!
Thank you, Sir... much appreciated , your excellent explanation, good day.
Thank you, thank you thank you! This is such an excellent video. The best I have seen out of all the ones I've been watching on how to troubleshoot my broken pilot light on an old American standard water heater. Really appreciated all of the detail. Lucky for me I do have an ohmmeter, multimeter, etc. don't know if I'll go through all the work to diagnose at part level as will probably just pay the $90 and get a whole new assembly with everything included and pop in and see if that works but thank you again this is an excellent video.
This told me what I needed to know on a job thanks buddy 👍
you guys are awesome making these vids
THANK YOU
Thanks for watching!
Excellent video. Good for a refresher
Great video! Excellent! I went to take a shower today and didn’t think the water felt very hot. I checked the water heater and tried lighting it and there was no spark. I don’t have time to go get parts and have a technician coming tomorrow. Video explained all the parts.
Glad it helped!
Fantastically informative thank you very much this was extremely helpful
