Suburban calls it an electrode. Just like my Attwood it appears to also generate a signal to the card. It's the only way for the card to know that the flame is going and keep sending power to the gas valve.
This is what stinks about the whole thing. If it's DSI we get to stay inside and turn the water heater on and off but when it breaks yer screwed. If we had the pilot model, like others said early on, 95% of the time it's just a matter of sanding clean the thermocouple probe. The old thermocouple probe is more mechanical in it's operation and physically expands and keeps the gas valve open. If it cools because of no flame, it closes the valve. The thermocouples are old school and very durable. I tried to load a page from the instal book but it wont work.
It sends 12 volts from the cabin switch to the high temp safety switch, then the temperature switch then to the card. It may have or seems like it would also have a melting "fuse" or "resistor" looking gizmo in the power line that melts open if the flame backs up into the housing area instead of going through the burner tube. The card sees the 12 v and starts the ignition spark and opens the gas valve, when the flame hits the electrode it sends a signal to the card to say keep the gas on.
That's what I'm seeing but I'm no RV tech and someone else may have more experience on them.
