Worked great as a rush replacement for my American Standard GN40L-2-3-6 water heater. It was a little challenging to remove the original, but once it was removed this one fit and fixed my issue with the pilot light turning off.

My water heater suddenly stopped working. I checked and there was no pilot light. I tried restarting the pilot light but it would not stay on. Good ole Youtube said that it was most likely the thermocouple. So I took out the pilot assembly and it was a 24 inch thermocouple. There is very little information about what thermocouple fits American so I decided to take a chance that it would fit. Fortunately, it fit perfect and now the water heater is working great again. I almost was going to get a new water heater but this inexpensive part saved the day.

My water heater exhibited symptoms of a defective thermocouple. Ordered this unit, replaced it myself, and now the water heater is working fine. This was the first thermocouple I've ever replaced.

It’s a part that wears out every two years or if your lucky it will last longer I like to have it on hand because it usually goes bad in the wintertime

Installed great and quickly. We used this exact same one 5 years ago and it just burnt out yesterday. Not bad for a $12.00-ish part.(Installed in a Williamson GWA 070 N S Gas Water Boiler, used the silver retainer but not the clip and it fit fine)

These thermal couples are invaluable when you need them. These are good quality thermostats that will last few years. I always keep a spare next to every water heater.

These are the best at a good price. I keep a few spares just in case my pilot light goes out.

My gas fireplace pilot would light but not stay on. $100.00 later, the repair man said I needed a new gas fireplace. It turned out to be the pilot thermocouple. This new 24" 30mV thermocouple was easy to install and fixed the problem.

This is the exact replacement for my Carrier furnace but as seems with so many things now does not last like they used to. My original lasted 30 years and the first replacement lasted just under 1 year. It seems to be the end, gets red hot from the pilot flame and eventually burns through and will fail. As others have reviewed, just keep another on hand for when this fails.
