My Sta Rite SR333 has been unused for some time. When I attempted to heat the pool it work well for a while then started firing the burner and shutting down. Thinking it was the regulator I replaced it with and identical regulator and the problem was not fixed.
I believe based on research that the ignitor could be bad even though the heater is firing.
My question is does the ignitor just light the Lp or does it light and have other jobs to maintain the flame?
