You missed explaining how (in a hot surface ignition system) where the flame sensor rod essentially conducts only half of the AC sine wave(average 90v) thru the flame where the ions in the flame then contact the burner nozzle which is grounded making it's way back to the control board as a rectified dc signal(usually 1 to 4 micro amps) The surface area of the grounded burner face is 4 or 5 times larger than the surface area of the rod. It's easier for the positive half of the AC signal to travel via ions from rod to burner face than it is for the negative cycle going the other direction from burner face to flame sense rod essentially turning ac into a small dc signal. There is nothing mysterious about the flame sensor rod. It's just a piece of smooth stainless steel. When you clean them don't use rough sandpaper or you will have to clean it again much sooner. Use steel wool or a scotch brite pad or fine sandpaper
Super! I just test this on a Carrier HK42FZ013 board. Use a diode for microwave, I got 8uA, without adding resistor. The board running without error. 100VAC on sensor connector. Thanks a lot Tim, you are the best!
Tim Muckey Hi I'm from Mexico and I have a stereo Delco for astro van, and want to put an auxiliary input, but I do not understand how it connects, could you explain me or would you do another video to do so as you do connections?, thank you for your attention , and I hope your answer. Sorry if I translated wrong jajajaja
1 kilo ohms resistor and one diode connect series to conductor toward ground. when spark comes on plug same time connect this conductor between flame rod and burner ground. thus help u to flame stimulate in your work shop.

Should have used an actual flame and an actual flame sensor connected to an oscilloscope so to prove the AC is converted into pulsating DC.
what are all the components you used on this board to make this work ?
Some of that is misinformation, could be misleading because you're missing the most important parts of how it really works.
Nice presentation but fells like missing something .. Thanks for sharing

Has there been an answer yet on the specs of the diode needed?
What size diodo? how many volts? and how many watts?
Nice presentation but it feels like it's missing something .. Thanks for sharing ..
AdnaneLondon This was just quick way to test modules. Thank You
talking about flamming, barf
Nice presentation but it feels like it's missing somthing .. Thanks for sharing
