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?

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?

I replaced the ignitor,  control board,  display board and the display keyboard and it still won't turn on.

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.

Thank You
