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 ### ⭐⭐⭐⭐ Bueno *by on Reviewed in Mexico 9 June 2026* Bueno sirvió bien ### ⭐⭐⭐⭐⭐ replacement on my 40-Gal Bradford-White water heater with Honeywell controller *by on Reviewed in the United States 20 April 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 ratingUPDATE 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 monthspilot 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 ### ⭐⭐⭐⭐⭐ Good Quality *by on Reviewed in Canada 12 December 2023* Works great ## 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/464344503-earth-star-750-temperature-resistance-millivolt-replacement-thermopile-generators-used](https://www.desertcart.gr/products/464344503-earth-star-750-temperature-resistance-millivolt-replacement-thermopile-generators-used) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-08*
