Thread: Slight pool heater problem.

    Question Slight pool heater problem.

    Hello again. I have a Jandy Lite 2 heater that was set up to be used as a dumb switch because something with the temperature sensor or switch was contently failing.
    This was great last year, but now the heater is not starting up all the time when we switch it on. I think it might be the rocker switch because if we flip it off and on a couple times it kicks on.
    Any other ideas on the possible issue or where to get one that's cheap?

    Thanks in advance.

    New issue starting at post 6.

    To test you can remove the rocker switch and jumper the two ends together. If it lights up, you have your answer, replace rocker switch.

    Guess I'll have to go get some wire and a LED.

    You don't need an LED. Just jump the two ends together and if it fires up, you have your answer.

    It fired up almost instantly. Where can I get a new switch inexpensively?

    Re: Slight pool heater problem.

    Hello, got a new problem with the heater. The pilot light won't stay light.
    Every time I let the knob rise up to set it "on" the pilot goes out before I can turn the knob. If I continue to hold the knob down in pilot mode, it's fine.
    Any advise? I would like to avoid calling someone if possible.

    Pilot generator is bad but to double check, use a volt meter set to milivolt to check the voltage that it is generating. If it not generating at least 450mv, it won't be enough to keep the pilot portion of the gas valve open.

    Ok, I had to get a volt meter, before I go to get a reading, should I do this cold or light the pilot and hold the gas open with the flame for a minute before getting a reading?

    You have to get the reading while holding down the knob on the gas valve. That reading has to be over 450 minimum in order for the pilot portion of the valve to keep the pilot lit.

    Well, that's it. I'm only getting .003mv. So, I'm calling someone to swap it out as I don't want to mes up with the gas line.

    You had the meter set to millivolts right? Not volts.
