SEN1114 SEN01114 Furnace Flame Sensor fit for Trane American Standard Furnace nikrothal 80 Sen0491 Sen00491 LUXRILIX

I purchase a lot of these to replace customer flame sensors. They work just as well and last just as long as OEM SEN0114 flame sensors. These are an excellent value for any business.

Installed one on my 18 year old furnace to increase the odds I would not return from a winter trip to find frozen/burst pipes flooding my house. Installation went smoothly and it functioned fine.Only complaint was package of 4, minimum. I am sure it is for commercial users, but the typical homeowner will need maybe one replacement in the life of his furnace. 1 is likely too few for anyone to make money.

Replaced original part appears to be same as OEM. Easy to replace fit perfectly. Good price hope it last as long as the original.

Had to replace this on furnace. Just a note it works well for replacing but you may have to bend a little to get it to fit for your particular furnace. This was a good buy.

Direct replacement for my gas furnace. Very easy DIY, worked right away. And as always, Amazon delivery was in a flash.

Good for what I needed

If you believe that products today are designed to fail, then this part would be the single point of failure for Trane furnaces. I have two of them and the flame sensor failed on both in the first 7 years.The good news is - they normally don't need to be replaced. The flame sensor makes use of the fact that the ionized flame in the furnace is a conductor, and when the current loop between the sensor and the burner is closed by the presence of a flame, a very small current (micro Amps) can flow.Over time the surface of the sensor rod will get coated with deposits from the combustion process and will no longer conduct a current. The controller will shut off the flow of gas right away if it does not detect the flame. This can be fixed by removing the sensor and cleaning it with a bit of steel wool. Once clean, it will be good for another 5 years.There are, however, certain furnace models that use fresh combustion air, and the air intake is designed so that it ends right above the flame sensor. When rain or snow or condensation is sucked into the combustion chamber, it speeds up the corrosion process on the sensor, and this does not only affect the metal rod, but also the other end with the connector. These sensors need to be replaced more frequently when they fail. 5 stars for this item because it is the correct part for both of my furnaces, but it would be 1 or 2 stars if I rated how well it functions once installed.

after many cleanings of my old sensor (common issue with Trane furnaces). I found it losing output to the board after cleaning. (less than 1 micro amp) After replacement now back to 6. All working great. And ya can't beat the price
