    Hayward pool heater error

    I`m getting the SF or 5F error on my heater. Just replaced the low temp sensor and still has the problem. If I unplug it for a minute or so and plug it back in,it fires up and shuts itself back off with the same code. I have the new high temp sensor and haven`t replaced it yet. Could really use some input. Thanks!

    Do I need to order IDXLTER1930?

    Yes the SF is the temp sensor that needs to be replaced and yes IDXLTER1930 is it.

    A word of caution: When working with gas and electrical you might want to consider a licensed contractor. Consider the value of your life and others around you.

    Thanks for the help. Wasted $60 on the wrong sensors. Should have just asked!
