Customer Question

I have a Hayward H150 natural gas pool heater. It was purchased in 2009. This year the heater has been touchy. It will usually ignite and then shut down in 5 seconds. Then it will try again 2-3 times, igniting for approx. 3 seconds. Then I get the IF code. Recently purchased new Display Board and Bezel assembly. No Change. Now I just tried a new Ignition Board. No Change. What's next ???
