flame detection electrode with a multimeter?
Hello there,
I was wondering if there is any way to check the state (new, old, about to fail) of a flame detection electrode with a multimeter?

The actual rod plays no part in flame sensing. Let me explain.... it's just a piece of metal that sits in the flame and is a conductive part of the circuit. The only thing that can go wrong with a flame sensor rod is that it becomes coated with gas byproducts which cause the rod to be insulated.
To measure the effectiveness of a flame rod.... you disconnect the wire from the rod and you put a meter in line set to DC microamps and you read the scale. The rod conducts thru the flame to ground.
If you suspect a flame rod sensor issue..... usually you just need to clean it good with a scotchbrite pad or very fine emery cloth. You want the rod to be very shiny and clean.
