Gas valves are NOT SERVICEABLE
Thermistor???
That is a temp sensor for a fridge
What are you referring?
Thermocouple? (Pilot flame is staying ON so thermocouple IS working---it generates millivolts that HOLD magnet open allowing gas flow. When you push down on knob you are bypassing that to get gas flow....then thermocouple takes over)
And that probe out the backside...
That is the ECO (Energy Cut Off....a high temp probe. BLOWS if water temp gets to 190*F to shut down ALL gas flow--no pilot/no main. Gas Valve has to be replaced if it blows)
