Excellent video! However, could you please help me with one thing: when you demonstrate the thermocouple operation with a multimeter, you mention that inside the copper is another wire that closes the circuit towards the thermoelectric decive. However, when you remove the thermocouple at 8:40, that thermocouple has another additional (white) wire connected, that was not present during the demonstration before. Is my assumption correct, that the white wire is basically the same, but instead of the coaxial "inner" solution, running outside of the copper tube? Thanks in advance!
That's an absolutely quality video. These videos where you demonstrate on real appliances what the books go through make a world of difference to our understanding. Thanks Derek
Very helpful. Many thanks. My thermocouple or thermoelectic device on my oven appears to have stopped working. Given its location I am going to try tickling the thermocouple with a small brass brush. If that does not work, can I replace the thermocouple?I live in the UK.
Hello from Greece. That was massively helpful. I 've found my father's old gas heater and I didn't know anything about how or why it did not work. This video provided me with substantial information and I managed to clean the jets, replace the thermocouple and now I am waiting for the harsh winter to come. Harsh outdoors though, cause indoors will be blazing HOT. thank you
I have a 3 burner dometic lpg gas stove in my camper if I push and twist black dial in and turn it to full flame then hit the ignition spark buton it ignites on full flame but goes out as soon as I realease the the black twist dial . but if I do this again and start it on a very very low flame it stays on . Then I can turn it up to full flame .. . And sometimes doesn't stay on no matter what I do . The other burners don't mess around like that. They start on any setting .
I look at three other videos and they had nothing on this video I was able to get my fireplace to work with out new parts. I now have a complete understanding of how thermocouple works
thank you , I have a gas heater and the light won't stay lit though I replaced the thermocouple and magnetic bobene but nothing chang , please help me, thanks.
Thank you, for your detailed demonstration. I would managed to trouble shoot a industrial gas stove's burner section in minutes, if I had seen this video earlier.
This has to be *one* of my favourite videos on your channel (they’re all amazing).The way you explained and demonstrated how a thermoelectric/thermocouple and a ASD works was absolute genius. I have a well better understanding now. Before I just used to hear time and time again about *‘over rides the safety device, over rides the safety device’* but now I actually get it! It’s like you have special vision and know the areas I struggle with and then know what video to upload 😂 Thanks so much Derek 👍🏻 Asian Jon. Training.
I have a 2 ring gas hob in my campervan. The gas keeps turning off and I think its the thermocouple. The hob has the correct butane injectors so I've ruled that out. Can the thermocouple just be completely removed (by a registered engineer) to allow the gas hob to work again?
Another amazing video Derek on the thermocouple and Asd, I've not tried the Asd test we did it once at tomkat Centre but due to the heat I think we had the fear of burning our hands. 😂🤣. Its all part of the training and learning new techniques on how to perform these tests. Great video.. 👍👍😀😀
I just want to say I very much appreciate your toturials, it helped me a lot. Currently I'm doing a gas course 2 evening a week, while doing that if something I'm confused about in the class room, I'll get home and search for it By Tomkat, always help, the trainees are trained by you are lucky people. Thanks for much I'll be back to watch more of your brilliant work
Great video. Hate that using all capitals at 4:17 has a huge effect on the voltage that comes from the thermocouple. 30mV vs 30MV is pretty significant. I always assumed that the pilot assembly was a fully mechanical device. A bit blown away that it's actually electric.
Your videos are brilliant but honestly, too verbose. Everyone want a decent message in decent amount of time. You should edit your videos and shorten these to not more than 25% of initial duration.
No sorry I make a video to give the information to my trainees if I think it needs to be 10 minutes then I will make a 10 minute video and if I think it needs to be an hour then it’s an hour. If you want 25 % of the time you will get 25 % of the information or just watch someone else on the subject 😜

Superb tutorial Thanks for posting
Top explanation if I were younger I would be doing this for a living...
Hi, I have an issue with my gas hotplate, it lit with no issues but it would shut off after around 10min. What could be the problem please?
The electromagnet works fine...but I cannot get a millivolt reading on 2 new thermocouples
Sir I'm also uae 🇦🇪 Last 26years i have experience natural gas technician
Amazing Video on how thermoelectric ,thermocouple and `ASD’ works. ‘Bilal Maqsood’ Tomkat trainee.
Nice video. It helped a lot understand better my stoves. Kudos
Thanx from Germany. great guy well explained
Thanks, was able to fix some space heaters.
Very helpful...I've purchased 2 now mine have the interupter and I can't seem to get them to work..please help..thanks
If you have replaced the thermocouple and the pilot still won’t stay lit then it’s the thermoelectric in the gas valve
That's an absolutely quality video. These videos where you demonstrate on real appliances what the books go through make a world of difference to our understanding. Thanks Derek
well done, THANK YOU 🙏

Sorry..i meant tested
Classic information
Quality video
Experienced teacher, you are marvelous. I did enjoy this lesson. Many thanks.

He is repairing that oven that's sitting by that gas meter, yea? That's not a kitchen table with a vice on it, is it? Workaholic award goes to.....

your video made love to my mouth by so much ad that it had.
but it was absolutely worth it! thank you for great video!!!
Hvala na objasnjenju pogresno sam mislio da radi na principu bimetala
Texted the electromagnet on the bench
Tested
Top man
Great video..thanks for your clear explination
Thank you for taking the time to do this video! Learned something new today!

Thanks derrick really appreciate your vids.
Love your explanation. God bless
Amazing and clear explinations as always, thank you!
🎉🎉🎉🎉🎉
Excellent tutorial. Thank you.

Very helpful thank you !
Brilliant informative video 👍👍👍👍👍
Always a pleasure, never a chore, listening to Derek is never a bore!👍

No you need a new thermocouple or hob
@@tomkatgastraining thanks, its a brand new hob but I'll order a different one. :-)
Very good video. Thanks.
Great video as always mate thank you.
This has to be one of my favourite videos
Tom what affects the oxygen being at 20.95
To say 20.60 is it pollution or height I’m thinking but don’t know.
Traffic polution is certainly one reason, or a room full of people, high CO.
Great video thanks 👍👍
Thank you for the education!
Very useful info thanks
Thanks 🙏 great video

Quality recap Derrick, knowledge people need if their going out serving fires etc…
