    Help with Hayward Heater

    Hi all,
    I need help. Heater was working fine a week ago. Heated pool overnight and it was maintaining 76 degrees, I believe it was not heating/ignited at the time and just maintaining the 76 degrees in morning when I raised the temp from 76 to 78 and suddenly the panel went out. After fussing with the circuit breakers and manual temp limiter switch for hours I was able to get the panel to light again. It ignited but then shut down after 5 seconds and gave me error code SF. I purchased a new thermistor and installed and it did not fix the problem. I was told by Hayward to replace the control panel. I did and when I installed the screen read the correct pool water temp but when I switched from standby to "POOL" the panel blanked out again with no error codes. The control panel screen will now not light up again. Any ideas?

    Re: Help with Hayward Heater

    Your board went off and won't light up at all? Sounds like something was either wired incorrectly and you now have a bad board, or you had a bad board to begin with. Hard to speculate without knowing all the details, though.

    From the troubleshooting guide, if you're experiencing this problem:

    "Verify 22-28 VAC is present between COM and AC terminals on ICB board. If voltage is present and display is blank, replace Display Board. If voltage is not present, replace ICB."
