Hello, looking for some help. We bought a house that has a Hayward H350? Pool heater. I worked great when we first used it. Then I got the SF code. We replaced the Thermister and presto everything was good for about two days. Now I am having a IF code issue. I set the heater to on, it fires up, runs for a few minutes and then shuts off ( seems normal) then won't reignite and gives the IF code after 3 more tries. Again if does fire up and runs for a few minutes then nothing. thank you.
