My Hayward Pool Heater H400 NG that won’t ignite. It tries 3 times but won’t start. On the Automatic Ignitor Board there is a component that is burnt, R45, I’m wondering if I replace that board if that will fix the problem being that the code it shows relates to ignitor and flame. Also I heard if you replace one board you have to replace the other, is that true?
Hi Pluto5,
Could you give us the exact model # of your Hayward Heater it may be something like H400FDN, H400ED2, H400ED1, etc…
Patrick, in my question from May 14th,under pool heater, from Pluto5.
My Hayward Pool Heater is Model # H400 IDL2
Thanks Pluto! Here is the Ignition Control Board for the H400IDL2 which you will require. This is shown as key #15 on this Hayward H400IDL2 Heater Diagram my understanding is if your heater is manufactured after 09/2004 then the other boards do not need to be replaced.
I replaced the ignitor, control board, display board and the display keyboard and it still won’t turn on.
My issue was ants burned out my board, but it sounds like you tried to replace that already. Have you given Hayward a call? What are they telling you?
