    Hayward Heater H400 service code SF

    Hi,
    My heater today has the service code SF which from the manual says replace temperature sensor (Thermistore failure). Is the
    part below correct? Just don't want to waste $70 for wrong part. Has anyone done this before? TIA

    Found part for it http://www.amazon.com/Hayward-IDXLTE...ds=idxlter1930, is this correct?

    OK, thanks. I am going to try to open the heater this weekend to see how hard it is to find the Thermistor.

    I took the Thermistor out & saw one of the wire got disconnected, I stripped both ends and tape them, heater working again, save myself $40, thanks for all the responses.

    Yep that will work also. Sounds like something chewed it.
