    Jandy Lite 2 LG250 won't ignite/fire

    I have replaced the temperature control assmbly with temperature probe into the heat exchanger and the analog on/off switch and analog temp dial.

    The pilot lite is on and it fired/ignited once but now won't fire no matter what I place the temp dial on.

    Heater is 6 years old.
    20x40 vinyl pool

    84 degrees

    How did you determine that those parts needed to be replaced?

    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.
