Aupoko Universal Gas Thermocouple, 600 mm Length, M8x1 End Nut and Head Tip Fit for BBQ Grill or Fire Pit Heater or Gas Water Heater

Nice replacement for the Ooni. Much better than $89 for the OEM part. Had to wiggle a tiny bit to get it in, and it was longer so I added a loop to the routing, but super easy and worked right away.

Used for fire pit. Worked great

great replacement part. had the pizza oven for about 4 years.then it started acting up. it would run for about 15-20 minutes ok, and then cut out.restart, last for a few minutes, then cut out. eventually it would not stay lit.The thermo couple appears to be defective in these.it was not made to be consumer replaceable, bottom panel uses triangle bits, to try to prevent opening.the bits are easily found on amazon. https://www.amazon.com/dp/B0B5GSMPV7 for a few bucks.took about 45minutes probably.

The thermocouple was easy to install. Had trouble finding a metric one locally.

Fire pit would light up just fine, but not stay lit. Assumed it was the thermocouple. 20 year old freestanding firepit, how to find parts? Old thermocouple had a name and model # Benan RR3100. That website and company are no longer around. The photo from this seller looked similar to my old one, so I searched the comments for that model # and a prior customer was looking for the same product, bought this one and it worked for him. Even though Amazon tagged this as "frequently returned" I figured that is because buyers are guessing. So I bought this, and it was a perfect match looks wise. Installed it (perfect fit) and voila! the fire pit stayed lit. I appreciate another buyer including the "clue" of the original model number in his comments,

I used this to replace the thermocouple on my Ooni Koda 12. Works well so far. I think they had a bad batch of thermocouples for a spell as this was a common problem. To access the thermocouple you need trangular dirver bits like these. https://www.amazon.com/gp/product/B083HQTCQ5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

To long for my application did not heat properly

My Ooni Koda pizza oven is now five years old and the thermocouple finally gave out. I contacted them and they do not offer replacement thermocouples. And they could not assist under the warranty because even though I had the original purchase receipt they require the serial number and unfortunately that’s on a cheap metallic sticker on the rear leg and it burned away. The original Ooni Koda 12 is not made to be disassembled - the base it attached to the top with many stainless steel rivets. Perhaps the reason that Ooni will not offer the part. I drilled out all of the rivets and replaced them with stainless steel sheet metal screws. Anyway, job done and I now have a working Ooni oven again. This replacement thermocouple is perfect.
