After watching this video I discovered whoever did my old fireplace didn't screw a proper thermocouple into the gas valve but instead rigged a non-standard thermocouple, attached it to the valve using an extra component with a wire which is welded/glued to a washer. Removing all that junk now with totally new components. If the gas valve location in mine didn't match this video exactly, I probably never would have figured it out. Thanks!!
I have an electronic ignition so no pilot light. My problem seems to be with the thermocouple not igniting. The gas flows and I can light the fireplace with a barbecue lighter. As soon as I turn it off, I'm right back to where I started. How can I test my thermocouple if I don't have a pilot light?
great video. All I did was hit my thermopile with sand paper and it worked. Saved me a ton of money and aggravation going into the holidays. I had people preparing for me for a full-on replacement/remodel and then I found this video and fixed it. Thanks!
Just saved me hassle and money! Thank you ! My thermocouple just wasn’t in tight enough so after testing and finding it still good, I reattached it and it now works great!
Thank you very much for finally solving my issue. What helped me was that you said that the flame had to be blue hot, but mine was yellow and pointing slightly away from the thermal-pile. There was a little ball of the fake ash in the way. I used a screw driver to push it out of the way, the flame is now blue, and the fireplace started right up.
hello all, thank you for the video and explanation!! Could you please offer me a link to take to pieces and then rebuild a thermoregulator (preferably Eurosit). Heather is 25 years and doing just fine. But, I need to service it once a year, and I AM needing a good video on the regulator. Looking forward I remain.

My fireplace thermocouple wire goes up into the chimney and my pilot light assembly only has a thermopile. Can I replace the whole assembly with a 3 in 1 assembly? Where both the couple and pile are on the pilot light?
I ordered a few things on your website and love these videos. Thank you! I had a brand new fireplace that would just randomly act like the thermocouple was bad. Ended up being loose where it screws in lol
Very good video. Simple and clear straight to the point. Your video just saved me big bucks and time from having to call an HVAC guy. I am going straight to your web site to shop for parts. Thanks again.
Can you do a video of how to test an electronic Sit valve with a multimeter? And also one of a regular Sit valve and Robertshaw valve. If you could explain to me how to do it or make a video and send me the link that would be awesome!
My thermocouple looks like it's broken at the backside end of where it screws in. That's probably leaking gas right. My propane tank lasts only about 3 hours.
Negative voltage reading, reversed polarity?? Anyone with an idea feel free to comment. With the help of this awesome video, I determined that I had a bad thermocouple and decided to replace the entire SIT pilot assembly on my 17-year old direct vent natural gas fireplace. After installing the new pilot housing it still did not operate correctly. It appeared that the new thermocouple was also bad, as the pilot light would not stay lit when releasing the knob to switch from "pilot" to "on". So I tested the voltage of the newly installed thermocouple and it reads as a negative number (No, I do not have the red/black leads in the wrong ports of the multimeter). If I switch the measuring tips hooking the red clip to the copper wire shaft and the black tip to the thermocouple nub (end that connects to gas valve) then I get a positive reading! It is as if the polarity on the thermocouple is reversed. Can this be? If so, did I cause it somehow, like accidentally grounding both ends, for example? Or could this be a manufacturing defect?
Hello, Sounds like it may be the gas control that is the issue. Not a reverse polarity thermocouple. If you contact fire-parts directly they should be able to help
@@fire-parts6588 Yes, it *was* the main gas control valve, thank you! I tested it using the tutorial on your website, and ordered the replacement valve from your website. I installed it and it works great!
Hi, I have a Gas Fireplace and it's like 18 yrs old, it just started not shutting off when I put it on like 1 it keeps running, do you think it's the thermostat???? Thanks
You helped me tremendously in this post and saved me a call to a technician. I tested the voltage and it was a bit low so I cleaned the thermocouple and thermopile and the fireplace lit up like a charm. Thanks for your help.
My pilot light is weak and doesn't stay lit when I let go of the pilot button. What could be the problem and should I still test the thermocouple and maybe also test the thermopile?
The pilot light should be cleaned first to create a strong blue flame, then test the thermocouple, and if found to be faulty replace. If the thermocouple readings are good then you may need to replace the gas control valve.
@@fire-parts6588 thanks for the info. So are you saying that if the pilot light goes out when I let go of the pilot button, then it could just be that the thermocouple needs to be cleaned? That would be great if it's that simple. I will try that tonight before testing it.
I just l it my fireplace for the first time (I've owned the house two winters now) following this video. I love you!! if you are single, i will marry you.
Excellent video, was having trouble with my gas fireplace insert, cleaned the thermacouple with a stronger gas pilot flame, as well as better overall flame for the entire log insert.
If your fireplace system has both a thermocouple and a thermopile the thermopile might be to blame. The thermocouple only holds in the pilot safety valve so if the pilot remains lit after you release the gas cock in the pilot position you know it's good. Once you turn the gas cock to the on position and make a call for flame its the thermopile that produces the milivolts to open the main gas valve. If you do not have flame it could be that your thermopile has failed, connections are poor or loose, thermostat or switch not calling for flame, gas cock left in pilot position, possibly a break somewhere in the wiring to or from the thermostat or switch, or the thermostat or switch has an unusually high resistance i.e not specific to a milivolt system. You might also want to ensure that the pilot burner is unobstructed and directing a strong blue flame towards the thermopile as well as the thermocouple (and towards the logset burners if it has 3 burner ports.)
After watching this video I discovered whoever did my old fireplace didn't screw a proper thermocouple into the gas valve but instead rigged a non-standard thermocouple, attached it to the valve using an extra component with a wire which is welded/glued to a washer.

Nicely done - thanks!
So is it the same for a thermopile?

Literally the best support videos I have seen in 15 years on youtube

If you do not light the pilot when testing it will read nothing....
Thank you so much my pilot light would go out, took a piece of sandpaper cleaned the thermocouple and pilot light now everything is working perfect!!
Thank you for the video!! You just saved me couple hundred dollars for a repair I was able to do myself!
Awesome job on video, clear and concise with lots of relevant, easy to understand information!
Very good video. Simple and clear straight to the point. Your video just saved me big bucks and time from having to call an HVAC guy. I am going straight to your web site to shop for parts. Thanks again.
Anyone can explain to me why some pilot assemblies have thermocouple only, some have thermopile only and some have both of them???? Thanks

Excellent Video. Very informative. Well done.
Thank You.
how does it read if the thermocouple isn't attached to the valve?
You need to hold in the knob on the gas control and use the probes as shown at the 2:08 minute mark
So how does the pilot light when gas comes out where the thermocouple screws in?
Fantastic video quality. I can see hear and understand. Clearly spoken and speach rate rate is great.
My thermocouple looks like it's broken at the backside end of where
it screws in. That's probably leaking gas right. My propane tank lasts only about 3 hours.
gas comes out of where it was screwed in when I press to start the pilot...
Very good easy to understand instructions. Great video
Save me some dough and I didn't have to ask the government for a solution.
Very helpful video. Thanks
Thank you! This helped me light my fireplace pilot light.
Informative video
Thanks
Does the gas solenoid valve work directly off this 8 to 30 millivolt signal or is it using an electronic circuit for threshold detection?

Hi, I have a Gas Fireplace and it's like 18 yrs old, it just started not shutting off when I put it on like 1 it keeps running, do you think it's the thermostat???? Thanks
it used to shut on and off as the room would get cold, now it just stays on and won't shut off unless I manually do it
Great video, very informative.
Thank you so much. I just vacuumed the pilot and it works. I couldn't imagine it was that simple.
You helped me tremendously in this post and saved me a call to a technician. I tested the voltage and it was a bit low so I cleaned the thermocouple and thermopile and the fireplace lit up like a charm. Thanks for your help.
great work , i needed to test a tc on a carver gas fire worked , nice one
If the pilot stays on when your doing this test does it mean I need a new valve assembly. I have a heat and glow fireplace.
And if the thermocouple reads over 30 mv?
👍❤️

@@stevef7331 Yes clean the pilot light so the flame is stronger and possibly the thermocouple
Many thanks for taking the time to inform.
This was amazing and worked! Thank you!
I just l it my fireplace for the first time (I've owned the house two winters now) following this video. I love you!! if you are single, i will marry you.
Geeta Lall that's funny lol
Geeta Lall Geeta I am looking for a wife? Are you still available?
Excellent video, was having trouble with my gas fireplace insert, cleaned the thermacouple with a stronger gas pilot flame, as well as better overall flame for the entire log insert.
it should be set to DVC(lowest voltage) scale
I can not keep pilot on when releasing the button and turning it to the left
@@sandybeaudin9258 /release while trying to turn...slowly!
Thank you, I needed this!
my pilot is on but the system won't light when we turn on the wall switch
Did you find the problem? One thing you can do is to check to make sure the holes where the gas exits into your fireplace are not blocked.
If your fireplace system has both a thermocouple and a thermopile the thermopile might be to blame. The thermocouple only holds in the pilot safety valve so if the pilot remains lit after you release the gas cock in the pilot position you know it's good. Once you turn the gas cock to the on position and make a call for flame its the thermopile that produces the milivolts to open the main gas valve. If you do not have flame it could be that your thermopile has failed, connections are poor or loose, thermostat or switch not calling for flame, gas cock left in pilot position, possibly a break somewhere in the wiring to or from the thermostat or switch, or the thermostat or switch has an unusually high resistance i.e not specific to a milivolt system. You might also want to ensure that the pilot burner is unobstructed and directing a strong blue flame towards the thermopile as well as the thermocouple (and towards the logset burners if it has 3 burner ports.)
very good video.
Sandpaper? No.
