Hi All, I’m back again.
My GSW 6G40PSV 40 gal, 34,000 btu, Propane hot water heater
is up to it’s old tricks again.
OK so, The hot surface igniter went bad. I couldn’t get the original Norton igniter so I fit a Robert Shaw to the burner, almost identical.
I hooked up everything. The system cycled, lite, ran for around 90 seconds and went out, restarted, same thing over again.
Now it goes through this process over and over again but will not stay lite. I tried changing the flame sensor, no change, cleaned the vain switch, no change, the vent pipe seems clean, plenty of air coming out the end.
Now I’m lost. It worked fine until the igniter failed now it doesn’t work. I should mention that it failed after sweeping the basement, cat and dog hair is a problem. I don’t think this should be related but in the spirit of full disclosure that’s when it happened.
