I have the same furnace as in your video and I have cleaned the sensor and burner heads. I have a voltage of 107 from the sensor to the ground. When I connect the meter in series with the flame rod and the burners fire up, I get zero miro amps. I think it may be the circuit board but not sure. Would there be another reason I do not get a reading? After a few seconds, the burners shut off. I have had it fire up for as long as 60 seconds and then stop.

Great video as always. I was checking the flame sensor signal on a mid efficiency furnace. When furnace fires up the microamp was around 1.7uA. But within a couple minutes the reading started to drop from 1.7uA to 0.6uA and furnace shuts off. I've checked all grounding, changed flame rod, verified gas pressure, cleaned burners, checked all connections and wires, checked rod distance from burner. The board is sending around 110vac to rod. Can it be a bad board? Thank

If you disconnect this green ground wire on the manifold would the flame go out?

Would you get a microamp reading if putting meter in series between the green ground wire and the manifold?

Yes. Also check the flame sensor to ac volts to ground

that looked like a ceramic flame sensor i thought you shoudnt get your oily fingers on the rod itself which it looks like you did. also you should mention what you used to clean the sensor like emory cloth or scrotch brite pad. i heard on boilers for examples you dont want to use steel wool as it will leave residue that will crystalize over the flame rod and insulate it preventing it from working

can u conifirm if it is dc or ac to verify flame sensor? also did u pull flame sensor wire and connect to meter then meter other cable to the sensor?

It's DC as you can see on the meters screen. Yes that's how it's connected
