Excellent explanation and video!! I found it because we were having trouble with our pilot light, which explains a lot, as well as the primary fix. What would also be helpful to learn is what happens to an aging thermocouple. Ours seems to be disintegrating - supposing this is due to 6years of constant heat, but that seems unfortunate given its designed use.

Tyvm!! Very clear and concise. You’re a good teacher friend!

Thank you I feel like my teacher made this way too complex than it need to be. So in summary uses 2 metals copper and iron. fuel, air, heat makes the thermocouple energized to hold open the solenoid which always gas to continue to pass threw the orifice so the pilot burner stays on when heat is being called That's really neat making a system that works and supports each other in a continuous loop.

No other video has made the observation that a combination of two different metals plus heat can produce a voltage; (I didn't know that) four minutes plus? A very short brilliant educational video that covers all the relevant points. Thank you, (you just saved me $225-Au, plus a three week wait for a technician; in winter) John Perth Australia (ticked and subscribed)..............

How did he save you money? Does it cost $225 just to learn about thermocouples or is that the cost of a repair? Asking because this short video was only descriptive of the part, but did not explain a repair operation. Surely you would need an additional video for the repair portion?

@beachbum4691

@@realSamAndrew there is no need for a separate video to explain detaching an existing failed thermocouple and replacing it with a new one, to anyone familiar with tools the changeover is very very basic. The $225 is an approximate cost for the repair guy (if you can find one) to come to the house; the basic callout fee typically being between $80 and $125 here in the Metro area, plus time on-site at $80 or $90 an hour, plus a very inflated cost for any parts, plus possibly a return trip if they haven't got the correct part with them?. Or they might simply turn up and say we don't work on gas heaters older than 10 years, or something like that?. I went to the local "large" hardware store, and bought a "thermocouple pack" with a dozen different fittings for I think it was $35, did the job myself in about an hour; I reckon I learned a lot and did a better job than the previous repair guy who left the unit with gas leaks which happily went up the exhaust flue; presumably taken up by the heat from the pilot light?. I reckon $225 is a very conservative guess?. Don't be scared to roll your sleeves up, over a lifetime it will save you a fortune and a lot of time. Best wishes. John. Perth, Western Australia :)

@@beachbum4691 thanks for the response and clarification. I see your original comment has also been expanded. This was not evident prior. I agree fully with everything you wrote. The only part puzzling is that this video still only explains how a thermocouple works. You don't need to know how or why it works to repair a furnace. You do need to know what one does and why the furnace is NOT working in order to identify the problem, then you must know the steps to locate the part in the unit and replace it. There are repair videos on KZread that show this based on symptoms, but I would not assume a consumer would go straight to a specific component by name (how would he know), and then learn what's inside instead of how to troubleshoot. Still seems to me a most indirect approach and probably not common. Good on you for doing the repair yourself and solving your problem 👍

Thanks for the explanation. Would have been nice to see you light it. though

Loved the video.. Quick question thou.... Does the pilot button allow gas to bypass and flow to delight it? Thank u

Very nice video. I have blue seal deep twintank fryer GT46. It is fitted with both thermopile and and thermopile with it gas vales. One of the fryer's pilot is not staying on. When I leave the pilot holding knob, the pilot switches off. I have checked both thermopile and thermo couple. Both are working fine. Please can you advice what else can be wrong? Is that mean the main gas valve has gone? Or any solenoid in the valve has stopped working? Can we replace solenoid or the whole valve needs replacing?

THANKS!

should thermocouple's tip burn red hot during the furnace on or pilot frame?

As one side of the thermocouple metal warms up, wouldn't the opposite side soon warm up due to conduction and therefore reduce the current needed to induct the solenoid? Thanks

I like the way you lecture on it , please how can we connect it

Why doesn't the copper tube need insulating? Is the generated electricity conducted by the copper tube?

What would cause a thermocouple to corrode and blow up at the tip so fast?

Is it possible to be able to use this to heat and melt metals in a crucible

@JumpermanTech

3 жыл бұрын

I'm not sure about melting metals but I don't really see this being used in any way for that. Thank you for watching! Maybe get yourself a torch with a gas that burns at high temps 🤷‍♂️

You forgot to say that the 30 millivolts is an open circuit reading and not a closed circuit reading. Closed circuit is when it is connected to the gas valve and will be lower.

bud do i need to have a special gas valve ?

So this is not actually how the thermocouple works but rather how a thermocouple works in an HVAC system. There's a difference between a thermopile and a thermocouple.

The Thermocouple copper tubing has wire running down its center (Usualy with high temperature insulation surounding it) somewhat like coax wire used for TV signals the copper tubbing connects one side of the circut, the wire inside the other.. the connector on the gas valve has an insultated central contact , and this is connected to small electromagnet in the gas valve safety system that will only allow the gas valve to supply gas "if" current is being generated from the thermocouple being heated from active pilot flame ,, lose the flame you lose the milivolt current driving the electromagnet and gas valve closes..its safety operation must be proven. blow out the pilot and its gas flow "must" stop in under 45 seconds. if it does not close the gas feeder valve feeding the applience and red tag it Do not operate until inspected by a licenced Gas techician .. you have a faulty gas valve that must be replaced by a licenced gas technician. some gas appliences also have a second Thermopyle generator that also uses the pilots heat to generate a higher voltage around 300 Milivolts that is capable of opening the main gas valve. without the need for power from the power grid..

You explained what a thermocouple does, but did not explain how dissimilar Metals produce DC voltage

@shsshs3895

Here is a made up explanation of why dissimilar metals will generate a voltage when heated. When a metal is heated, the electrons in the metal speed up and wants to move away from its heated area. When two dissimilar metals, such as steel and copper (that are joined together), are heated, the electrons in each of the metals (steel and copper) wants to move away from the heated area, but since copper is heavier than steel, copper has more electrons, and thus copper is able to push its electrons past the steel electrons, and thus creating a voltage and current. Two metals of the same kind can also create a temporary voltage (and current), if one is heated and the other is not heated, and are afterwards, joint together. The above is an explanation that was just thought about, to support the idea, that someone mentioned, that dissimilar metals (joined together) will generate a voltage when heated.

seems like such a tiny voltage to operate an electromagnetic valve to open or shut down a big volume gas pipe. 30 milivolts? is that .03 of a volt? and at how much miliamps? seems like such micro power. this tiny charge doesn't go to a powered valve, this small charges operates the valve...wow...how? so weak

No, you get this totally wrong. You claim this works via electricity - which is true only for electronic metallic strip *measurement* thermocouples connected to a voltage meter. This *control* type of thermocouple works simply by heat expansion pushing the rod out of the end of the thermocouple to keep the gas valve open while hot. You can demonstrate this to yourself simply by telling a new thermocouple and heating the sensing end while watching the rod at the far end come out. Please delete your voiceover to this otherwise excellent video and rerecord it.

thanks!!! that didn't make sense... I wrote this comment above: "seems like such a tiny voltage to operate an electromagnetic valve to open or shut down a big volume gas pipe. 30 milivolts? is that .03 of a volt? and at how much miliamps? seems like such micro power. this tiny charge doesn't go to a powered valve, this small charges operates the valve...wow...how? so weak how can this work" however the expansion of metals is a powerful force, able to depress a spring on the other end.....now it makes sense. I hate misinformation when it comes to engineering....this guy made such and authoritative sounding maration...but he didn't know how it works. Anyone can replace a thermocouple, but I wanted to know how it works.....thanks man
