Very true. Sometimes you gotta try something and mess up so you can learn something and do it right. Thomas Edison once said about making the lightbulb “I have not failed. I’ve just found 10,000 ways that won’t work.” The biggest thing is learning something and not repeating the same mistakes. Eventually you get to the point where you know when you are in over your head and ask for help.

[@michaellicitra7632]

Mikey Pipes! Another great video! A little on thermocouples: Thermocouples work due to a thermoelectric effect that occurs when two dissimilar metals are connected and the connection joint is heated. Most likely the thermocouple in this gas appliances is a copper - constantan type T thermocouple but I am not really sure right now. The outer wire is in the form of a copper tube and inside the tube is an insulation layer covering a solid wire (most likely constantan material in this case). The end of the thermocouple in the fire is where the wires are welded together. This wire arrangement is like a coaxial cable TV cable. When the pilot is lit it heats the welded end of the thermocouple and a small voltage is produced. (around 10-30 mV depending upon the flame temperature). This voltage is enough to energize the solenoid coil in the gas valve just enough to keep it open and maintain the pilot light gas flow when the gas appliance main valve is off. This is why you need to hold the valve pilot button down long enough so you can give the thermocouple enough time to heat up and increase its voltage output to produce just enough voltage to keep the pilot solenoid open. Now imagine you were in a spaceship travelling to Mars or some other distant planet. You need power on the trip to call home once a day to check in with the Mrs. And see how the kids are doing. On a long trip your batteries won’t last very long…and you are too far from the sun for those solar panels to work….so what to do? Use a nuclear reactor! Believe it or not, you can make power by using arrays of thermocouples surrounding a long lasting radioactive Plutonium 238 source. The Plutonium decays naturally causing a heat-up of the thermocouples and a voltage is produced - now you can call home! Yes the very same principle used to open your gas valve on your gas appliance at home is used to power spacecraft in distant places where batteries and solar cells no longer can function.

[@nwredneckturner1508]

Michael nailed it. The thermocouple has no liquid in it. It's just 2 dis-similar metals joined at the 'bulb' that gets heated by the pilot flame that creates voltage to energize the electro-magnet that holds the pilot valve open. I pulled the magnet assembly out of a hot water tank gas valve to test thermocouples under a 'load'. Sometimes they will read OK on a meter when not connected to anything, but under a load they wont produce enough voltage to power the magnet to keep the pilot on.Generally 15mv is minimum to keep the pilot on. Keep doing what you do Mikey Pipes!

[@stevebabiak6997]

@@PipeDoctor I have bought cheap thermocouples - from Walmart of all places - and they are still in service going on ten years or so. The tips on the thermocouple can corrode from the constant high temperature they experience in normal operation. Then the weld between the dissimilar metals weakens or breaks, and no or too little voltage is produced. At least that appears to be how the thermocouples (only a handful, I am not a plumber or HVAC tech) failed that I’ve replaced.

[@blitzblutz]

Thanks. When Mikey said there was fluid in the bulb, I was going to have to Google it.

I found it interesting also how he refered to the thermocouple as having fluid in it. However first thermocouples genterate a current frm disimmiler metals being fused together and heated to produce higher outputs. Next the test performed will not give an acurate diagnosis as only OCV ( open circuit voltage will be measured, the proper way to test thermocouple output is with a test connector installed in the circuit so the thermocouple can be checked under load. In regards to "fluid" the poster appears to be confusing a mercury flame sensor switch that was used in intermittent pilot applications before the electronic flame sensing circuits became the standard control.

Aye sometimes you already know what the problem is but you have to do the steps so the home owner doesn’t fell like he got over charged lol for a two min job lol great video

[@shaundonovan2193]

Great video. Thank You

[@planetsized]

what kind of thermocouple on a furnace has fluids in it? ive only ever heard of or seen TXV sensing bulbs with fluids in them. from what i understand thermocouples generate electrical current by utilizing two dissimilar metals to initiate a thermoelectric effect. this is new information to me and i haven't been able to find anything more with the internet, if you could tell me more about this or where i can read about it i would appreciate it EDIT: just read about mercury and hydraulic pilot safeties, never heard about them when i was in school. was this what you were referring to?

Love it. Your videos are like OTJ training for me.

Hello pipe doctor I’m from Huntington Sta, I love to watch your videos I’ve learned a lot from you, I’m an hvac tech having an issue with a Navien ncb 240 error code eo12 I cleaned intake filter, checked manifold gas pressure on high fire was 4.8wc, checked for ground, blockage intake and exhaust, combustion analysis , everything looks good but still pulling the same error every other day do you know what I’m missing from your experience before I call Navien support? Thanks for sharing your experience great jobs

I just installed brand new and a new transformer

Venting issue or blocked condensate

[@johnwaby4321]

Just great when someone else has a go at trying to fix it . Causes even more problems. 👍👍

The best is when everything's disassembled when you get there.

7:49 I thought the thermocouple produced a voltage when two different metals (typically Chromel and Alumel) were heated. That's how jet engines measure EGT (exhaust gas temperature)

I remember snow when I lived in Buffalo now I live in charlotte no snow here

[@reggiepotts3437]

Thank you, super job

[@SuperVstech]

Did you just say a thermocouple has a fluid in it? Um... no. It’s a bimetallic strip that when heated produces voltage... The copper wire is a tube with an insulated conductor inside...

[@cheddahman1604]

Good job finding the bad fluid lol😂😂😂

[@jcaleca60]

Mikey pipes I give you credit I am retired now To go out on a day like today HVAC guys That's what we do

[@DONALD1951]

Won’t stay lit.. change the thermocouple..cheap and easy to change.. 100-1 thermocouple to gas valves.
