Split from Hayward h250 gas heater
Did this finally work for you? I had this problem show up last year with the LO code. Was able to get rid of that by replacing the limit swicthes but now i am getting a IF code coming up and it lights fine then goes out.
I have already replaced the entire control board, the limit switches, but not the pressure switch or the ignitor.
Would this fix this issue? i have pulling my hair out on this.
