    Jandy Lite 2 (circa 1990) won't fire up

    Hi All, I was wondering if someone can help me with the troubleshooting of my old heater. Guide for me heater is attached.JandyPoolHeaterTroubleshooting.pdf

    * I've got pilot light lit with blue flame
    * 400 mv when I touch one probe to PP and the other PP-TH. Troubleshooting guide says 500 mv.
    * can't see voltage (0 mv) across fusible link...
    * Ditto for pressure switch

    I probably need some teaching on the multi-meter, but I've got it set to measure voltage on DC, is that correct? And then touch one side of the fusible link?

    Thanks!

    Did you test fuse-able link for continuity? When you turn up the thermostat past your water temp (call for heat) your millivolts should drop by about half.

    Seems like everything in the fusible link and pressure switch was working. Since I've been traveling for work these last couple of weeks, we had to call in someone to fix it. The just under 400 mv being put out by the thermo-whatever (converts temp to a current) was not enough. But, they replaced the pilot light and the heater is working like a charm. Now I just need to make a winter cover for the heater....
