Internal resistance (25°C), varies with specifications and length between 1,500 mΩ and 4,500 mΩ.Specifications: Length 24” Rating: 750 mv - b. Normal working temperature 700-750°C. - c. Connecting type: spiral type and two-pole plug-in type. - d. Lengths: 24 inches （609mm）from shop GAS COMPONENTS STORE - Sufficient voltage is crucial: Ensure your pilot burner nozzle is fully open or properly drilled; replace old nozzles to provide enough flame heat to heat the thermopile. If the valve fails to open, clean the pilot nozzle—insufficient flame heat will prevent the thermopile from actuating the valve. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B074KFT8RY | | Best Sellers Rank | #224,194 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #54 in Fireplace Replacement Parts | | Customer Reviews | 4.6 4.6 out of 5 stars (541) | | Date First Available | June 23, 2017 | | Item Weight | 1.13 ounces | | Item model number | SMT-RDO007 | | Manufacturer | Made In China | | Package Dimensions | 5.59 x 2.56 x 1.57 inches | | Part Number | SMT-RDO007 | ## Images ![750℃ temperature Resistance Millivolt Replacement Thermopile Generators Used On Gas FirePlace/Water Heater/Gas Fryer Cluster Thermocouple for 24" Fireplace - Image 1](https://m.media-amazon.com/images/I/51KEcA4Z-GL.jpg) ## Questions & Answers **Q: Can I use this on my wall furnace?** A: Hello, you can use it **Q: Can this thermopile be used on older gravity gas furnaces?** A: Can be compared with the old, generally universal, thank you. **Q: Will this work in my rheem xg38t06n38uo water heater** A: Suitable for more heaters, as long as the shape is the same, it can be replaced, thank you. **Q: Is this a replacement for an empire r1054 thermopile (fits a dv215)?** A: I am not familiar with the R1054 Thermopile you are speaking of. I would think that it would work due to the fact a thermal coupler is a very simple device. I would pull the coupling out of the Thermopile and do a visual comparison. If free returns are just order it and then do a side-by-side comparison. Sorry I could not have been more help, but that is pretty much what I had to do when I was ordering one for my gas stand-alone heater. It worked. ## Customer Reviews ### ⭐⭐⭐⭐⭐ replacement on my 40-Gal Bradford-White water heater with Honeywell controller *by S***I on April 20, 2024* UPDATE 2024 SEP 20 - after more investigation, the REAL problem was that the old pilot was weak; maybe residue was clogging something, I'm not sure; I replaced the pilot line and the pilot flame was much bigger, circling the thermopile; after that, everything worked; when I first replaced the thermopile, I tested the original one with a lighter, and it was definitely broken, so I think this was a case of multiple parts of the assembly reaching the end of their lives at different but similar times; anyway, for that reason, I am reverting to the original rating UPDATE 2024 SEP 17 - this thermopile stopped working yesterday, which means that it worked for approximately 5 months; admittedly, it worked well for those 5 months, and it cost only $14; still, 5 months seems short; when I say it "stopped working", what I mean is that voltage climed very slowly and failed to reach operating voltage even under a hotter flame than the pilot; I remember that I tested it when I first got it, and the voltage rocketed under the same test flame; so, it deteriorated over those 5 months pilot would not hold on my Water Heater (40-Gal Bradford-White water heater with Honeywell controller); I remembered that the pilot was out another time recently, and the LED blinked "weak millivolt" that time; that time, everything restarted normally, but not this time; I tested the sensor with a voltmeter and the voltage supplied when it was under pilot heat grew extremely slowly; together, decided that the sensor was bad; I installed this morning and everything seems to work perfectly; I was not sure until I had it in my hand how it compared to the original, but it seems to be functionally identical, same length, fits perfectly in the bracket; the wires were solid, like the original (so, try not to bend them too much); I didn't like the fork terminals they put on, the original terminals were blade terminals and I wanted to reuse the male blade terminals that were already there, so I needed to cut them off and install my own female blade terminals; still, a great item at a great price; and, for stuff like this, I appreciated the availability of fast shipping ### ⭐⭐⭐⭐⭐ Fix Your Gas Logs Yourself With This Easy Fix *by D***K on January 31, 2026* I don’t use my gas logs very often, and on the day before a big ice storm I couldn’t get them to stay lit, so I ordered this to fix the problem. It arrived the next and was easy to install and now the gas logs work perfectly. I highly recommend this if you are having the same problem. ### ⭐⭐⭐⭐⭐ Great price, works perfectly. *by R***A on November 21, 2025* My gas fireplace kept going out. Pilot stayed on no problem, but when running, after 20-30 minutes it would suddenly shut off. 3 fireplace techs were expensive and useless, none fixing it. I did some research, seemed like the thermopile might be failing. Took about 20 minutes and this very well-priced part and it's up and running normally again. Perfect fit, perfect function. ## Frequently Bought Together - 750℃ temperature Resistance Millivolt Replacement Thermopile Generators Used On Gas FirePlace/Water Heater/Gas Fryer Cluster Thermocouple for 24" Fireplace - Heat N Glo Thermocouple For Heat And Glo And Hearth & Home Fire Places - Lennox 74L57 Gas Fireplace Thermocouple --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/53275737-750-temperature-resistance-millivolt-replacement-thermopile-generators-used-on-gas](https://www.desertcart.gr/products/53275737-750-temperature-resistance-millivolt-replacement-thermopile-generators-used-on-gas) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-11-12*
