Honeywell CQ100A1013 24-Inch Replacement Thermocouple for Gas Furnaces, Boilers and Water Heaters

Awesome price. My boiler usually eats one of these per year so I bought a couple as reserves.

Works well and met the need for my 50 year old IGC furnace! Always buy a spare just in case you need it immediately.

This thermocouple was a near-perfect replacement for the original on my 26-year-old GE-branded Rheem 40 gallon water heater. The pilot light mysteriously stopped working and I saw quotes in my area for anywhere from $350-$500 for a professional wrench-turner to come out and replace it. I'm a bit intimidated when it comes to working with natural gas devices, but honestly the biggest challenge of this project was being sure there were no gas leaks during the reassembly, and if you are patient and a bit mechanically inclined then there is no reason why you can't do this yourself. In my state, California, we are phasing out gas heaters in 2027, and having to convert to all-electric means not only investing thousands in a new tank but also upgrading the house electrical system and pulling permits, which will likely require a professional installer if that work is above one's pay grade (as it is mine.) A $500 service call just to replace this little item for a 26-year-old heater? It's not an insignificant consideration and might be enough to push some people to make the switch to electric before they otherwise were prepared or needed to. If nothing else, this 10-buck part has bought me time to prepare for the inevitable switch, and it's got our hot water flowing again which makes the family very happy. The only negative I have to say is that the 24-inch model was a bit too long for my model heater; the 18-inch would have been the exact fit. If you get into the same situation, just roll up the extra copper coil and tuck it out of the way, it will still work fine.

When my furnace thermocouple went out on the coldest day in January, this part was an absolute lifesaver. It arrived the very next day and proved to be a perfect, seamless replacement to get my heat back up and running quickly. The included universal adapter fittings made the installation process straightforward, easily mounting right into the existing setup. It is a heavy-duty, reliable element that feels like it will last a long time. If you find yourself in a heating emergency or just need a solid 30-millivolt replacement for your gas furnace or water heater, this gets the job done perfectly.
