It's 4yrs old, but is in a weekend house so I turn it off/on each time I'm there. Now it takes a long time primed w/ the pilot lit before it will take off. Often the pilot will go out during priming. A couple times it has given the double blinking light "Thermopile voltage low".how old is the heater, what are the symptoms, the thermocouple would be the least expensive to replace
it should be in the flame
and because of this, they tend to get dirty with carbon build up
pull it out, clean it. reinsert it. making sure it is fully inside the flame
and try it one again time more
Thank you, I will start with this.
If the thermopile needs replacing, is it possible to replace it without buying a complete burner assembly on this AO Smith GCV 40 301 unit?
